Examples

Questiopn 1.
Make notes using the passage given below:

Holidays give students rare, unhurried time. Reading during this break strengthens attention, grows vocabulary, and offers calm, screen-free relaxation. Yet many children drift away from books because of powerful distractions – mobile games, streaming shows, or constant notifications. Access can be another barrier: library fees, the cost of new books, or uncertainty about which titles are age-appropriate. A simple plan overcomes most hurdles. Fix a short daily reading slot of 20-30 minutes, preferably at the same hour. Use the “five-finger rule” to choose the right level – if five words on a page are too hard, try another book. Mix genres so reading stays fresh: stories, biographies, science comics, travel writing, even magazines. Create social nudges – reading buddies, family read-alouds, or a weekly book-share. Schools can support with classroom libraries, book talks, and reading journals; parents help most by modeling the habit themselves, limiting screen time, and letting children choose. With steady practice, holidays turn into a launchpad for deeper comprehension, creativity, and confidence that lasts through the year.

Question 2.
MIND MAPPING is another technique of Making Notes :

Look at the following passage about Rabindranath Tagore and with the help of Mind Mapping, how one can make notes:

Rabindranath Tagore (1861-1941), most eminent modern Bengali poet was also a critic, essayist, composer and author of short fiction and innovative in Bengali literature. He is known outside India principally in English translation. Gitanjali, a song offering (1912), his free verse recreations of his Bengali poems modelled on medieval Indian devotional lyrics, won the Nobel Prize for Literature in 1913, its first award to an Asian. Representative translations followed, of philosophical plays such as Chitra (1913) and The King of the Dark Chambers (1914) and his novels The Home and the World (1919) and Gora (1924). His short fiction often comments powerfully and courageously on Indian and social concerns, in the collections Hungry Stones (1916) Broken Ties (1925) and The House Warming (1965) and in the novella The Broken Nest brought out his powerful depiction of social issues. Tagore had an excellent command of English, but he wrote primarily in Bengali and tirelessly encouraged other writers of the Indian vernaculars. (The Oxford Companion to English Literature)
Answer:

Read the passage and make notes:

The word ‘Literature’ is really hard to define. Many interpretations are made about the word. But all are incomplete. Some opine that literature is the mirror of life, some others say that it is the criticism of life. Whatever may be the controversy about the word, we may say that literature is that which reflects life. The branches of literature are poetry, drama, novel and short stories. Poetry is of two kinds, imaginative and realistic. Drama is either a comedy or a tragedy.

Novels are also of many kinds historical, psychological, realistic, scientific and regional. Short story is one which stands very close to life despite a little scope.

Exercise

Make Notes for the following exercises.

Question 1.
Photosynthesis is the process by which chlorophyll-containing, organisms – green plants and algae – capture energy in the form of light and convert it to chemical energy. Almost all the energy available for life in the earth’s biosphere – the zone in which life can exist – is made available through photosynthesis.

In the first stage of photosynthesis, chlorophyll absorbs sunlight. Chlorophyll is the green substance in leaves, which is able to trap the energy of sunlight and use it in the process of making carbohydrates.

Within the leaf, there is a small amount of water. The energy, which the chlorophyll has trapped of the sun, is used to split the water in the leaf into hydrogen and oxygen. Most of the oxygen is released into the air. In the second stage, the chlorophyll uses the energy absorbed from sunlight to combine the hydrogen (which is obtained by splitting the water) with carbon dioxide (which the leaf obtained from the air). Then, after several complicated changes, the hydrogen and the carbon dioxide are combined in such a way that a carbohydrate is produced. This carbohydrate is called glucose. Later, using glucose as its most important building material, the plant can make substances called amino acids and proteins. These chemicals are needed for the growth of both plants and animals.

Something else happens during photosynthesis that is of the greatest importance to us. A constant supply of oxygen is released into the air by plants. At the same time, carbon dioxide, which would poison us if we breathed too much of it, is nearly all used up.

Photosynthesis is one of the most important chemical processes in the world. This is because it is the primary method of food manufacture, and the primary method of oxygen manufacture.
(Adaptedfrom Funk and Wagnall’s New Encyclopedia)
Answer:
Photosynthesis

• Definition : Process where chlorophyll-containing organisms capture light energy and convert it into chemical energy.
• Importance: Supplies energy for all life on Earth.

• Glucose produced: Used to create amino acids and proteins.

Key Products

• Oxygen: Released into the air (important for respiration).
• Provides energy and building blocks for plant and animal growth.

Significance

• Oxygen supply: Essential for animal life.
• Carbon dioxide removal: Reduces harmful CO₂ levels in the atmosphere.

Question 2.
Intensive reading is aimed at mastering the structures and vocabulary apart from reading for comprehension. The pupils have more opportunities to learn the aspects of the language through intensive reading. If properly carried out, even non-native speakers of English may develop themselves better users of English than the native speakers of English in writing. Intensive reading can also be done in the absence of the teachers. So, by spending more time on intensive reading, one may get language skills in English. And the only practicable means of learning a foreign language as a second language is through intensive reading. The intensive reading has some prerequisites like: the readers should be able to identify the words and sentences spoken orally and acquire sufficient speed in reading.

In intensive reading, the pupils pay attention to almost all aspects of language. And further the effort of learning the language is supplemented by extensive reading. Extensive readers should be interesting stories. Magazines, newspapers and variety of story books will form the material for extensive reader. The two main themes of extensive reading are reading for pleasure and reading for information. Extensive readers facilitate passive vocabulary in the learners. And it also consolidates active vocabulary. So, the teachers should regularly give some assignment and thus forcing the students to library. Sending the students to library can be done as a means of assertive punishment also. As the students read more and more books, their power of phonic analysis improves and makes the learner to pronounce any word that he sees for the first time. Group discussion also can be done on extensive reader.

Question 3.
Language that we use keeps the human being in an exalted position when compared to other living things. Language is needed for all the people irrespective of their status. And, it is used from our birth till death. Language is a means of communication. We use the language as a medium through which thoughts are conveyed from person to person. It is considered a means of social control. No society can function without language. Language is part and parcel of our life. We cannot imagine a society without language. If no language, then the progress of mankind will be blocked. We will be deprived all the niceties of life that we enjoy now. Habit formation is necessary for language learning and using. Learning a language involves establishing the links between the language forms and their meanings.

The process of establishing the link between the forms and meanings are three, namely, (i) the form, (ii) the meaning and (iii) their association. In speaking, the speaker associates the exact form with the meaning that he knows, and in understanding he associates the meaning with the form he’leamed from others. The speaker of the language is conscious of the words he uses and form meaningful sentences that can make the listener understand. All the time the speaker adjusts the sounds to meaningful words and words to meaningful sentences. Language has three functions. The first one is the informative function, where information is communicated. The second function of the language is expressive, where we express our feelings, emotions and our opinions. The third function of the language is directive, where we teach others, give advice etc. So, for meaningful life we require language.

Question 4.
Body shaming is a harmful behaviour where people criticize others based on their physical appearance. This includes making negative comments about someone’s weight, height, skin colour, or other physical traits.

Body shaming can take many forms such as: weight-based shaming: This is one of the most common forms, where people are criticized for being “too fat” or “too thin.” People often comment on someone’s weight without realizing how hurtful it can be. Comments like “Why are you so fat?” or “You look like a stick” are examples of weight-based shaming. Skin Colour Shaming: India has a deep-rooted issue with colorism, where people are judged for having darker skin tones, with people often making comments like “You’ll look better if you lighten your skin.” This type of shaming is not only hurtful but also promotes a harmful preference for fair skin over darker skin. Height Shaming: Tall or short, people can face body shaming based on their height. Comments like “Why are you so short?” or “Do you play basketball because you’re tall?” may seem innocent but can make teenagers feel out of place or self-conscious about their height. Face and Features Shaming: Teenagers often face comments about their facial features, such as nose shape, jawline, or even acne.

Remarks like “Your nose is too big” or “Why do you have so many pimples?” can deeply affect a teenager’s self-Confidence. Social media often promotes unrealistic beauty standards, making young people feel that they must look a certain way to be accepted. Influencers and celebrities post edited pictures that show only their “perfect” sides, leading teenagers to feel pressured to look the same. Unfortunately, this creates a cycle where teenagers compare themselves to these impossible standards and feel inferior when they cannot match them. Moreover, trolls and cyberbullies on social media leave hurtful comments on people’s pictures, furthering body shaming. Movies often show heroes and heroines with fair skin, slim bodies, and certain “ideal” features. Characters who don’t fit these standards are often cast as sidekicks, comedians, or villains, indirectly telling the audience that only certain looks are acceptable for “good” or “successful” people. This sets a high and unrealistic standard for teenagers, who may feel pressured to look like these stars. Some might even resort to extreme diets, over-exercising, or skin- lightening treatments to match these unrealistic standards. (https://en.wikipedia.org/wiki/Bodv shaming!

Question 5.
The healthy eating plate is a guide to eating balanced meals, especially for individuals with diabetes. It emphasizes portion control across three main food groups and advises limiting food intake if overweight. To create a healthy plate, start with a small plate or bowl about the size of your outstretched hand: Vegetables: Fill half your plate with a variety of vegetables, either cooked pr raw. Include vegetables of different colors to ensure a range of nutrients. Avoid counting tubers like potatoes as vegetables, as they are starches that can raise blood sugar levels significantly. Starches: Reserve one-quarter of your plate for whole grains and healthy starches, which contain fiber and have a milder effect on blood sugar than refined starches like white rice, bread, or pasta. If refined starches are preferred, consume them in smaller portions.

Protein: Use the remaining quarter for lean protein sources such as beans, nuts, yogurt, fish, eggs, and poultry. These can be eaten alone or incorporated into dishes like soups, salads, and stews. Red meat should be eaten rarely, if at all. Additionally: Use healthy oils, such as sunflower or safflower oil, while avoiding processed oils like margarine or vegetable shortening. For beverages, plain water is best. Coffee or tea without sugar is acceptable. Avoid sugary drinks entirely, and limit fruit juice, as it can rapidly raise blood sugar. Whole fruits with natural fiber are a better alternative. Eating slowly, appreciating food, and stopping when satisfied rather than full are also essential habits. Some people find that replacing starches with proteins and vegetables aids in weight loss and stabilizes blood sugar levels. Hence, use a small plate and divide it as follows: half for vegetables, a quarter for protein, and a quarter for healthy starches.

Question 6.
Nature is a master storyteller, and nowhere is this more evident than in the changing seasons. Among all seasons, Summer and Winter stand at opposite ends of the spectrum, each bringing its own unique charm, character, and experiences. Together they shape our daily lives, habits, moods, and even our relationships with family and friends.

Summer is a season of warmth, energy, and abundance. Long sunny days fill the world with golden light, and temperatures rise to levels perfect for outdoor activities. Children play freely in parks, families head to beaches and swimming pools, and the air is filled with laughter and excitement. It is the season of barbecues, picnics, and evening gatherings under the open sky. Nature generously offers an abundance of fresh fruits during summer- juicy berries, sweet melons, mangoes, and peaches refresh both body and spirit. People dress lightly in cotton and bright colours, reflecting the cheerful mood of the season. Schools remain closed, making summer the most awaited time for students to relax, travel, and explore new experiences.

Winter, in contrast, wraps the world in a quiet, peaceful stillness. Cold temperatures, shorter daylight hours, and snowfall in many regions transform the landscape into a silver wonderland. Outdoor life slows down considerably as people seek warmth indoors. Families gather around fireplaces, sharing hot drinks like tea, coffee, and soups. Cozy sweaters, blankets, and warm clothing become daily companions. Indoor activities like reading, board games, cooking, and storytelling bring families closer together. Winter festivals and celebrations add colour and warmth to the cold months.

Despite their differences, both seasons share something beautiful and universal—they offer precious time for families to bond, for individuals to relax, and for loved ones to create memories that last a lifetime.

Question 7.
The First Industrial Revolution kicked off in Britain in the late 1700s, powered by the invention of the steam engine and the mechanization of textile production. Imagine a world where everything is done by hand – then, suddenly, machines begin to take over. This era brought the birth of factories, and people from rural areas moved to cities, hoping to find work in these newly constructed industrial hubs. The Industrial Revolution fundamentally altered the way people lived and worked, making products available at unprecedented scales.

Building on steam power, the Second Industrial Revolution was marked by the rise of electricity, steel, and chemical industries. This is the era that saw the birth of modern mass production. Thanks to inventions like the electric light bulb, telegraph and telephone the Second Industrial Revolution sped up urbanization and reshaped entire economies.

The Third Industrial Revolution, often referred to as the Digital Revolution, began in the latter half of the 20th century. This revolution was powered by computers, internet technology, and automation. The world became “smaller,” as the internet connected people, information, and services across the globe in an instant. The Third Industrial Revolution changed how we work, communicate, and live, creating the digital age and laying the foundation for our current tech-driven world.

We are currently in the midst of the Fourth Industrial Revolution, where the fusion of physical, digital, and biological systems is transforming the world even faster. AI, machine learning, 5G networks, biotechnology, and blockchain are at the . heart of this revolution, making technologies smarter and more interconnected. The Fourth Industrial Revolution is marked by rapid changes that promise to reshape industries, redefine jobs’, and even challenge our notions of what it means to be human.

Question 8.
Civic sense refers to the sense of responsibility that every citizen feels towards the society and the public spaces they share with others. It is the awareness that one’s actions affect not just oneself but the entire community. A person with good civic sense respects public property, follows traffic rules, keeps surroundings clean, and behaves in a manner that promotes the well-being of all. Unfortunately, civic sense remains one of the most neglected values in Indian society today, despite rapid economic and technological progress.

The absence of civic sense is visible everywhere around us. People litter roads and public places without hesitation. Garbage is dumped in open spaces and water bodies, causing severe pollution. Traffic rules are violated openly, leading to accidents and chaos on roads. Public property such as benches, walls, and transport facilities are damaged carelessly. Noise pollution is created through unnecessary use of loudspeakers and vehicle horns. All these actions collectively degrade the quality of life for every citizen.

The root cause of poor civic sense lies in inadequate education and upbringing. Children who are not taught the importance of social responsibility from an early age grow into adults who are indifferent to public welfare. Schools, families, and communities all share the responsibility of nurturing civic values in young minds.

Several steps can be taken to improve civic sense among citizens. Civic education must be made a compulsory part of school curriculum. Awareness campaigns through media, street plays, and community programmes can bring about attitudinal change. Strict enforcement of laws related to littering, traffic violations, and public property damage will create accountability. Most importantly, every citizen must realize that a clean, orderly, and ha’rmonious society begins with their own individual behaviour.

A nation truly progresses when its citizens take pride in both their rights and their responsibilities.

Question 9.
Unified Payments Interface (UPI) and other digital payment tools have changed how we pay for groceries, tuition fees, cab rides, and even street-side tea. The biggest advantage is speed: money moves instantly, twenty-four hours a day, with a simple scan of a QR code or a tap on a contact. Because transaction histories are stored in apps, it’s easier to track expenses, split bills with friends, and budget weekly pocket money. Digital payments also reduce the need to carry cash, lower the risk of loss or theft, and help small shops accept money without card machines. Cashback offers, automatic bill reminders, and linking to savings accounts can nudge better money habits.

However, convenience comes with responsibilities. Fraudsters rely on urgency, confusion, and trust. No legitimate service asks you to enter a PIN to receive money; payment PINs are only for sending. Never share OTPs, screen-share with strangers, or click shortened links that ask for banking details. Keep SIM cards locked with a PIN; a SIM-swap can hijack accounts. Always verify the merchant name that appears before you confirm a transfer, and prefer your saved “trusted” payees for large amounts. On borrowed or public phones, avoid logging into payment apps. Turn on app-level biometrics and enable instant transaction alerts through SMS and email.

For everyday discipline, set a monthly digital spending cap and review the passbook view every Sunday. Reconcile small autopay subscriptions that you no longer use. Update KYC only inside the official app or website, not via links from messages. When a payment fails, wait for the reversal instead of trying repeatedly. Finally, remember that digital trails matter: they help resolve disputes but also reflect your habits. Treat your financial data like your front-door key – guard it, label it, and use it carefully.

Question 10.
Social media helps us learn, connect, and express opinions, but it also spreads rumours faster than facts. Misinformation thrives on four ingredients: speed, emotion, novelty, and gaps in our knowledge. Posts that provoke outrage or fear are shared quickly, while corrections arrive late. To protect yourself, slow down at the moment of emotion. Ask: Who benefits if I believe this? Does the claim have a date, location, and source I can verify? Screenshots without links, cropped images, and voice notes with anonymous “insiders” deserve extra scepticism.

Simple verification steps go a long way. Search a key sentence in quotes to see if credible news outlets have reported it. Check the account’s history: is it new, posting only extreme content, or using stolen profile pictures? Look for hallmarks of manipulation – mismatched shadows in images, unusual blinking or teeth in videos, or audio that does not match lip movement. When a claim involves health, law, or finance, prioritise official sources and expert bodies over influencer opinions.

Being a responsible user means not amplifying doubtful material. If a forward feels urgent, it’s a red flag. Add friction: wait ten minutes; often the urge passes. When you do share, include the source and date so others can judge reliability. In groups, set norms: “No forwards without links,” or a weekly slot for fact-checks. Schools and families can run short workshops on , confirmation bias – how we favour information that supports what we already believe.

Finally, remember that silence can be strength. You don’t have to comment on every issue to be informed. Curate your feed: follow a few quality sources instead of dozens of noisy ones, and use platform tools to report harmful content. Digital citizenship is not just about freedom to post; it is about discipline to verify, contextualise, and, when needed, refrain.

Question 11.
Disasters turn hazards into human loss when exposure and vulnerability are high. India faces cyclones, floods, earthquakes, droughts, heatwaves, and landslides. The Disaster Management Cycle emphasises continuous action across four phases: mitigation, preparedness, response, and recovery. Mitigation reduces risk before events: land-use zoning, coastal embankments, retrofitting schools and hospitals, enforcing building codes in seismic zphes,’ restoring wetlands and mangroves, and risk-informed infrastructure. Preparedness builds capacity: hazard mapping, early-warning systems (IMD, INCOIS), stockpiling relief, drills in schools, mock exercises with NDRF/SDRF, community task forces, and public awareness on evacuation routes and first aid.

Response activates when alerts escalate: Incident Command Systems coordinate search, rescue, and relief; evacuation shelters provide water, sanitation, and health services; special attention goes to elderly, children, and persons with disabilities; and rapid needs assessments guide resource deployment. Recovery begins as waters recede or tremors stop: debris clearance, damage assessments, cash and livelihood assistance, rebuilding homes with “build back better” standards, restoring services (power,. roads, telecom), and psychosocial support. Post-disaster reviews capture lessons for policy and budgets. Linking the phases creates resilience: mitigation lowers impact, preparedness speeds response, effective response shortens recovery, and recovery invests in better mitigation. Communities are strongest when local knowledge, science, and governance align.
Answer:
Title of Text : Disaster Management Cycle

Main Idea

• Disaster Management = A continuous cycle to reduce risks, prepare, respond, and recover from disasters.

Views about Disasters (very brief points)

• Disasters occur when hazards (cyclones, floods, earthquakes) lead to high human loss due to exposure and vulnerability.
• India faces various types of disasters: cyclones, floods, earthquakes, droughts, heatwaves, and landslides.

Disaster Management Cycle Phases

Mitigation → Reduces risk before events:

• Land-use zoning, coastal embankments.
• Retrofitting schools/hospitals.
• Enforcing building codes in seismic zones.
• Restoring wetlands and mangroves.
• Risk-informed infrastructure.

Preparedness → Builds capacity :

• Hazard mapping and early-warning systems (IMD, INCOIS).
• Stockpiling relief and community task forces.
• Drills in schools and mock exercises with NDRF/SDRF.
• Public awareness on evacuation routes and first aid.

Response → Activated during alerts:

• Incident Command Systems for search, rescue, and relief.
• Evacuation shelters with essential services (water, sanitation, health).
• Special attention to vulnerable groups (elderly, children^ disabilities).
• Rapid needs assessments guide resource deployment.

Recovery → Begins after the event:

• Debris clearance and damage assessments.
• Cash and livelihood assistance.
• Rebuilding homes with “build back better” standards.
• Restoring services (power, roads, telecom).
• Psychosocial support and post-disaster reviews.

Linking the Phases

• Mitigation lowers impact, preparedness speeds response.
• Effective response shortens recovery, recovery invests in better mitigation.
• Communities are strongest when local knowledge, science, and governance align.

Question 12.
All living organisms are composed of cells, the fundamental units of life. However, not all cells are structured the same way. Based on their internal complexity, all cells fall into one of two major categories: prokaryotic or eukaryotic.

Despite their differences, both cell types share some essential components that are necessary for life. Every cell is enclosed by a plasma membrane, which acts as a selective barrier between the cell’s interior and the outside world. Inside the membrane is the cytoplasm, a jelly-like substance that fills the cell. Both prokaryotes and eukaryotes use DNA (deoxyribonucleic acid) as their genetic blueprint to store information. They also both contain ribosomes, which are tiny structures responsible for building proteins according to the instructions from the DNA.

The primary distinction between the two lies in their internal organization. Prokaryotic cells, found in organisms like bacteria and archaea, are structurally simpler and typically smaller. Their most defining feature is the absence of a nucleus. Instead, their genetic material, a single circular chromosome, is located in a region of the cytoplasm called the nucleoid. Prokaryotic cells also lack other membrane-bound organelles, meaning their internal components are not separated into compartments.

In contrast, eukaryotic cells are generally larger and more complex. These cells, which make up all other forms of life including plants, animals, fungi, and protists, have a true nucleus. This membrane-enclosed organelle houses the cell’s DNA, keeping it separate from the rest of the cytoplasm. Furthermore, eukaryotic cells contain a variety of other specialized, membrane- bound organelles, such as the mitochondria for energy production, the endoplasmic reticulum for processing proteins and lipids, and the Golgi apparatus for packaging and transport.

Answer:

V. Short Answer Questions

Question 1.
Explain the disease Amoebiasis with regards to its pathogen, symptoms, carrier, and mode of infection.
Answer:
Amoebiasis (Amoebic dysentery) is an intestinal disease caused by a protozoan parasite that affects the digestive system.

• Pathogen: The disease is caused by Entamoeba histolytica, which lives in the large intestine of humans.
• Symptoms: Common symptoms include constipation, abdominal pain, stomach cramps, and in severe cases, stools containing mucus and blood.
• Carrier: Houseflies act as mechanical carriers, transferring the parasite from contaminated material to food.
• Mode of Infection: The infection spreads by consuming food or water contaminated with faecal matter containing the parasite. Houseflies help transmit the cysts from infected faeces to food.

Question 2.
How does the transmission of each of the following diseases take place?
(a) Amoebiasis
(b) Malaria
(c) Ascariasis
(d) Pneumonia
Answer:
(a) Amoebiasis: Transmitted by consuming food or water contaminated with cysts of Entamoeba histolytica. Houseflies act as mechanical carriers by transferring cysts from infected faeces to food.

(b) Malaria: Spread through the bite of an infected female Anopheles mosquito, which injects the Plasmodium parasite into the human bloodstream.

(c) Ascariasis: Occurs by swallowing eggs of Ascaris lumbricoides present in contaminated food, drinking water, or soil.

(d) Pneumonia: Transmitted through respiratory droplets or aerosols released by an infected person during coughing or sneezing. It may also spread through contaminated eating utensils.

Question 3.

(a) MALT
(b) CMI
(c) AIDS
(d) NACO
Answer:
(a) MALT: Mucosa-Associated Lymphoid Tissue – a lymphoid tissue associated with mucosal surfaces, constituting nearly 50% of the body’s lymphoid tissue.
(b) CMI: Cell-Mediated Immunity – an acquired immune response mediated mainly by T-lymphocytes.
(c) AIDS: Acquired Immunodeficiency Syndrome – a disease caused by the Human Immunodeficiency Virus (HIV) that weakens the immune system.
(d) NACO: National AIDS Control Organisation – the Indian organization that works with government and non-government agencies to create awareness, prevent HIV/AIDS, and implement control programmes.

Question 4.
What is innate immunity? What are its barriers?
Answer:
Innate immunity is the body’s natural, non-specific defence mechanism that is present from birth. It provides the first line of protection against invading pathogens by preventing their entry and destroying them through various defence barriers.

Types of Barriers:
i) Physical Barriers:

1. The skin serves as the first protective barrier against microorganisms.
2. Mucous membranes lining the respiratory, gastrointestinal, and urogenital tracts trap and prevent microbes from entering the body.

ii) Physiological Barriers: These include hydrochloric acid (HCl) in the stomach, saliva, and tears, which destroy microbes or inhibit their growth.

iii) Cellular Barriers: Certain white blood cells (leucocytes) such as neutrophils, monocytes, macrophages, and natural killer (NK) cells eliminate pathogens through phagocytosis and other defence mechanisms.

iv) Cytokine Barriers: Virus-infected cells release interferons, which protect neighbouring healthy cells from viral infection.

Question 5.
Explain the term “Addiction” in respect of drugs and alcohol abuse.
Answer:
Addiction is a psychological dependence on drugs or alcohol in which a person repeatedly seeks these substances to experience pleasure, euphoria, or a temporary sense of well-being.

• Compulsive Use: The affected person continues to consume drugs or alcohol repeatedly, even when it is harmful or unnecessary.
• Increased Tolerance: With repeated use, the body becomes tolerant, requiring progressively higher doses to produce the same effect.
• Vicious Cycle: Continued use creates a cycle of dependence, making it increasingly difficult for the individual to stop without assistance.
• Dependence: Long-term addiction results in physical and psychological dependence. Stopping the substance may produce withdrawal symptoms such as anxiety, nausea, sweating, restlessness, and discomfort.

Question 6.
Differentiate between Innate and Acquired Immunity.
Answer:

VI. Long Answer Questions

Question 1.
Describe the life cycle of Plasmodium with a labelled diagram.
Answer:

1. The life cycle of Plasmodium is completed in two hosts: humans and the female Anopheles mosquito.
2. The cycle starts when an infected female Anopheles mosquito bites a person and injects sporozoites into the bloodstream.
3. These sporozoites travel to the liver, enter liver cells, and multiply repeatedly to produce merozoites.
4. The merozoites leave the liver and invade red blood cells (RBCs), where they multiply again and finally rupture the RBCs.
5. The bursting of RBCs releases a toxic pigment called haemozoin, which is responsible for the periodic chills and high fever seen in malaria.
6. Some merozoites differentiate into gametocytes inside RBCs. When another female Anopheles mosquito feeds on the infected person, it ingests these gametocytes.
7. Inside the mosquito, gametocytes develop into male and female gametes. Fertilization forms a zygote, which develops into an ookinete and later into an oocyst. The oocyst produces numerous sporozoites.
8. The newly formed sporozoites migrate to the salivary glands of the mosquito. During its next bite, they are injected into another human host, thereby repeating the life cycle.
9. Among all malaria parasites, Plasmodium falciparum causes the most severe form of malaria. Mosquito bite → Sporozoites → Liver → Merozoites → RBC cycle → Gametocytes → Mosquito →Gametes → Zygote → Oocyst → Sporozoites

Question 2.
What is Immunity? Describe the various types of immunity.
Answer:
Immunity is the body’s natural ability to protect itself from disease-causing microorganisms. It is provided by the immune system, which identifies and destroys harmful pathogens.
1. Innate Immunity: Innate immunity is a non-specific defense mechanism that is present from birth. It protects the body by preventing the entry and spread of foreign organisms.

Types of Barriers:

Physical barriers:
1. Skin acts as the first protective barrier against pathogens.
2. Mucous membranes lining the respiratory, digestive, and urogenital tracts trap microorganisms and prevent their entry.

• Physiological barriers: Stomach acid, saliva, and tears destroy microbes or inhibit their growth.
• Cellular barriers: White blood cells such as neutrophils, monocytes, macrophages, and natural killer (NK) cells eliminate invading pathogens through phagocytosis.
• Cytokine barriers: Virus-infected cells produce interferons, which protect neighbouring cells from viral infection.

2. Acquired Immunity Acquired immunity is a pathogen-specific defense system that develops after exposure to antigens and possesses immunological memory.

• During the first exposure, the body produces a primary immune response, which is relatively slow and less intense.
• During subsequent exposures, a secondary (anamnestic) immune response is produced, which is much faster and stronger due to immunological memory.

Acquired immunity mainly involves two types of lymphocytes:

B-Lymphocytes:
1. Produce antibodies that circulate in the blood and destroy pathogens.
2. This is known as humoral immunity.

T-Lymphocytes:

1. They do not produce antibodies directly but help B cells and destroy infected cells.
2. They are responsible for cell-mediated immunity (CMI) and also play a major role in organ transplant rejection.

3. Active and Passive Immunity: Acquired immunity is further classified into Active Immunity and Passive Immunity.

Active Immunity:

1. Develops when the body is exposed to antigens such as living or dead microbes or their products.
2. The body produces its own antibodies.
3. It develops gradually but provides long-lasting protection.

Passive Immunity:

1. Occurs when preformed antibodies are transferred directly from another individual.
2. It provides immediate protection, but the protection is temporary.
3. Examples include IgA antibodies present in colostrum passed from mother to infant and maternal antibodies transferred through the placenta to the developing foetus.

Question 3.
Explain the transmission of Human Immunodeficiency Virus (HIV) and its replication in man with the help of diagram.
Answer:
Human Immunodeficiency Virus (HIV) is a retrovirus containing an RNA genome enclosed within an envelope. It causes Acquired Immunodeficiency Syndrome (AIDS) by weakening the body’s immune system.
1. Transmission of HIV: HIV spreads only through infected body fluids and not by casual contact.
The major modes of transmission are:

• Unprotected sexual contact with an infected individual.
• Transfusion of infected blood or blood products.
• Sharing contaminated needles or syringes, especially among intravenous drug users.
• Mother-to-child transmission during pregnancy, childbirth, or breastfeeding.

2. Replication of HIV in Humans :

• Entry into Macrophages: HIV first enters macrophages, where it begins its multiplication.
• Reverse Transcription: Inside the host cell, the viral RNA is converted into DNA with the help of the enzyme reverse transcriptase.
• Integration: The newly formed viral DNA integrates into the host cell DNA and becomes a provirus.
• Formation of New Viruses: Using the host cell machinery, the provirus directs the synthesis of viral RNA and proteins, which assemble into new HIV particles.
• Infection ofT-Lymphocytes: The newly formed viruses infect helper T-lymphocytes (CD4 cells) and continue multiplying within them.
• Progressive Destruction: Large numbers of viruses are released, infecting additional CD4 cells and causing a steady decline in their number.

3. Effect on the Immune System :

• As the CD4 (helper T-cell) count decreases, the immune system becomes weak and less effective.
• The infected individual becomes highly susceptible to opportunistic infections caused by bacteria, viruses, fungi, and parasites.
• Continuous destruction of helper T-cells eventually results in immunodeficiency, making the body unable to defend itself against common infections.

Question 4.
Explain cancer with reference to its causes, diagnosis and treatment.
Answer:
Cancer is a disorder in which body cells divide abnormally and uncontrollably, resulting in the formation of tumours. Malignant tumours invade nearby tissues and spread to other parts of the body through metastasis.
1. Causes of Cancer :

• Carcinogens: Cancer develops due to cancer-causing agents called carcinogens, which transform normal cells into cancer cells.
• Physical Agents: Exposure to ionizing radiation (X-rays and gamma rays) and non¬ionizing radiations (UV rays) can damage DNA and initiate cancer.
• Chemical Agents: Chemicals, especially those present in tobacco smoke, are major contributors to cancers such as lung cancer.
• Biological Agents: Certain oncogenic viruses and the activation of proto-oncogenes (cellular oncogenes) may also trigger cancer development.

2. Diagnosis of Cancer :

• Early Detection: Early diagnosis greatly improves the chances of successful treatment.
• Biopsy and Histopathology: A small tissue sample is collected and examined microscopically to confirm the presence of cancer.
• Blood and Bone Marrow Tests: These investigations, particularly useful in leukaemia, help detect abnormal blood cell counts.
• Imaging Techniques: Methods such as X-rays, CT scans, and MRI are used to locate and identify tumours inside the body.
• Molecular Diagnosis: Advanced molecular techniques help detect genetic susceptibility and identify cancer at an early stage.

3. Treatment of Cancer: Cancer treatment usually involves one or more of the following methods:

• Surgery: Removal of the tumour by surgical operation.
• Radiotherapy: High-energy radiation is used to destroy cancer cells.
• Chemotherapy: Anti-cancer drugs are administered to kill rapidly dividing cancer cells. Hair loss and other side effects may occur.
• Immunotherapy: Biological agents such as interferons are used to stimulate the immune system to recognize and destroy cancer cells.

Question 5.
Describe the commonly abusing drugs by drawing their chemical structures.
Answer:
Commonly abused drugs are broadly classified into opioids, cannabinoids, and coca alkaloids. Most of these substances are obtained from flowering plants and mainly affect the central nervous system (CNS), leading to addiction.
1. Opioids: Opioids bind to specific opioid receptors present in the brain and gastrointestinal tract, thereby reducing pain and producing sedation.

Morphine:

1. Obtained from the latex of the plant Papaver somniferum.
2. It is a powerful pain-relieving (analgesic) drug and sedative used in medicine.
3. Chemically, it possesses a complex multi-ring structure.

Heroin (Smack):

1. Chemically known as Diacetylmorphine.
2. It is produced by acetylation of morphine.
3. It acts as a strong CNS depressant, slowing body functions and causing severe addiction.

2. Cannabinoids: Cannabinoids act on receptors mainly present in the brain, affecting memory, mood, coordination, and behaviour.

Source:

1.  Obtained from the plant Cannabis sativa.
2. Common products include marijuana, hashish, ganja, and charas.

Active Compound: The principal active chemical is Tetrahydrocannabinol (THC).

Effects :

1. They influence the cardiovascular system.
2. Produces euphoria, hallucinations, and altered perception.

Structure: Cannabinoids possess a phenolic ring attached to a long hydrocarbon chain.

3. Coca Alkaloids (Cocaine):

• Source: Cocaine is extracted from the South American plant Erythroxylum coca.
• Action: It blocks the reuptake of dopamine, increasing its concentration in the brain.

Effects:

1. Produces alertness, excitement, increased energy, and euphoria.
2. Excessive use may result in hallucinations and nervous disorders.

4. Other Commonly Abused Substances:

• Hallucinogens: Plants such as Atropa belladonna and Datura contain hallucinogenic compounds that alter perception and produce hallucinations.
• Misused Medicinal Drugs: Certain prescribed medicines like barbiturates, amphetamines, and benzodiazepines are often abused despite their therapeutic use.
• Tobacco: Tobacco contains nicotine, which increases heart rate and blood pressure. Long-term consumption is associated with cancer and several respiratory diseases.

Question 6.
Describe the harmful effects caused by alcohol and drug abuse. Discuss its prevention and control measures.
Answer:
Alcohol and drug abuse, especially among adolescents, can lead to serious physical, mental, emotional, and social problems.
1. Harmful Effects:

• Immediate and serious effects: Abuse of drugs or alcohol may cause reckless behaviour, violence, coma, heart failure, respiratory failure, brain damage, or even death. 1
• Warning signs in young people: Common signs include poor academic performance, frequent absenteeism, poor personal hygiene, social isolation, depression, and aggressive behaviour.
• Spread of infectious diseases: Sharing contaminated needles can transmit infections such as HIV/AIDS and Hepatitis B.
• Long-term health effects: Continuous use damages the liver (cirrhosis), brain, nervous system, and during pregnancy it may also harm the developing foetus.

Effects of steroid abuse in sports :

1. Females: Masculinisation and irregular menstrual cycles.
2. Males: Reduced sperm count and enlargement of breasts (gynecomastia).
3. Adolescents: Stunted growth and severe acne.

Social and financial consequences: Addiction may result in theft, family conflicts, emotional stress, poor relationships, and financial difficulties.

2. Prevention and Control Measures :

• Avoid peer pressure: Adolescents should resist negative influences and develop confidence to make healthy choices.
• Education and counselling: Awareness programmes and counselling help young people manage stress, accept failures positively, and adopt healthy habits such as sports, reading, and yoga.
• Seek support: Individuals should approach parents, teachers, friends, or counsellors for guidance and emotional support.
• Recognise warning signs early: Parents and teachers should identify behavioural changes at an early stage and take timely corrective action.
• Professional treatment: People affected by addiction should receive help from doctors, psychologists, rehabilitation centres, and de-addiction programmes. With proper treatment, counselling, and determination, recovery is possible.

For systematic learning, students can include AP Inter 2nd Year English Grammar with Answers and Form Filling a Life Skill in English Inter 1st Year in their daily study routine.

AP Inter 2nd Year English Form Filling a Life Skill with Answers

A form is a document with spaces in which answers to questions can be written or information can be recorded in an organized way. (Acc. to Cambridge English Dictionary)

Forms are a fundamental and essential part of modern life. It is a lifelong skill-from birth registrations to end-of-life paperwork-needed for school/college admissions, scholarship applications, and employment as well. They are used to collect standardized information for a wide range of purposes.

Whatever the type of form it may be, all forms can, in general, be divided into two types

I. Physical forms
II. Digital or Online Forms

1. Academic Forms: Admission forms, scholarship applications, exam registration forms, etc.
2. Job-Related Forms : Job application forms, internship forms.
3. Official Forms : Aadhar enrollment form, Passport application, voter ID registration, driver’s license application, etc.
4. Bank Forms: Account opening form, cheques, deposit slip, loan application, etc.
5. Common Forms: Railway reservation form, APSRTC bus pass form, yoga registration form, etc.

Bank Forms :

People can make bank transactions such as depositing or withdrawing money, transferring funds, paying bills, or applying for loans. To perform these activities, customers fill in different bank forms – for example, deposit slips, withdrawal slips, Demand Draft (DD) forms.

Common Bank Forms and Their Purpose :

Deposit Form :

A deposit form is used to deposit money into the customer’s bank account. It helps the bank record the transaction correctly and ensures that the money is credited to the right account. Every deposit slip requires the customer to write essential details such as name of the account holder, account number, date, amount, and type of deposit (cash or cheque).

Look at the following filled in form for your understanding.

Practice:

Dr. D. Parvathi Devi went to the State Bank of India and deposited an amount of Rs. 10000 (in 500/- denomination) in her SB (savings bank) account today. Her account number is 23013023011, and her mobile number is 940000940.

6. Ten Thousand Rupees
7. 10000
8. 10000

Withdrawl Form :

A withdrawal form is used to withdraw small/medium amounts in cash at the branch. It is a small slip given by your bank branch to take cash from your own account at the counter-without using a cheque or ATM card or when you don’t have your ATM card, or ATM limit is not enough- It’s valid only in the same branch.

Note : It is a must to take our Passbook along with us at the time of visiting bank to withdraw money.

Have a look at the below filled withdrawal form :

Practice:

2. 15-06-2026
3. Twelve Thousand Rupees
4. 12,000/-
5. S. Ravi Kumar

Withdrawing Money Through Cheques :

A cheque is one of the most common and important tools of withdrawing money used in the banking system. It is a written order issued by an account holder (called the drawer) to their bank, instructing the bank to pay a specific amount of money to a person or organization (called the payee) from their account. With this facility, customers can draw large amounts of money.

Types of Cheques

1. Bearer Cheque – Payable to the person holding the cheque.
2. Order Cheque – Payable only to the person whose name is written on the cheque.
3. Crossed Cheque – Can only be deposited into a bank account, not taken directly.

Let’s see the Activity :

Practice:

Mr. K. Kalyan is an employee in a company. His employer Y. Sunanda issued a cheque for an amount of Rs. 25000/- to K. Kalyan today towards his salary. Fill the following cheque leaf using the above details.

Answers:

1. K. Kalyan
2. 07-06-2026 (Exam Date)
3. Twenty-five Thousand Rupees
4. 25000/-
5. Y. Sunanda

Demand Draft :

A Demand Draft is a prepaid bank instrument used to pay money to someone (the payee) in another place or the same city. Since the bank collects money first and then issues the DD, it’s considered safer than cash and more reliable than cheques (cheques can bounce; DDs don’t). While issuing DDs, banks levy charges (usually a minimum amount) which is called Exchange / Commission.

DD is generally used for – College/Exam fees, application forms, government payments, when the receiver demands a guaranteed mode of payment.

Example :

Practice:

Mr. N. George has taken admission for B.Tech at JNTU Anantapuram. He applied for a DD for Rs. 30000/- (in Rs. 500/- denomination) to be paid towards admission fee to The Registrar, JNTU, Anantapuram payable at SBI, Anantapuram by visiting SBI, Main Branch, Kurnool.

Customer : That sounds good. Does it have a decent display for watching movies? .
Shopkeeper : Yes, the display is Full HD with anti-glare, so it’s perfect for streaming movies or working in bright environments.
Customer : Great! Is it good for light gaming as well?
Shopkeeper : It has integrated Intel UHD Graphics, which is fine for light gaming and casual use, but for more intense gaming, you’d need something with a dedicated GPU.
Customer : That’s perfect for me. How’s the battery life?
Shopkeeper : The battery lasts around 8-10 hours with regular use, which is great for long working hours or travel.
Customer : I’ll take it! Can I pay by card?
Shopkeeper : Absolutely! I’ll process your payment now. Thank you for your purchase!

Answer:
You : Mom, I’ve got a seat in that college I applied to, but it’s really far from home. I’ll be staying in a hostel.
Mother : That’s such great news, my dear! But I’m a bit worried about you staying away from home. How will you manage everything, especially your health?
You : Don’t worry, Mom. I’ll do my best to stay healthy. I’ll try cooking for myself whenever I can.
Mother : Cooking for yourself is a great idea! That way, you can control what you eat. Make sure to eat balanced meals – plenty of vegetables, fruits, and proteins. Hostel food can sometimes be unhealthy. .
You : I know, I’ll try to avoid unhealthy snacks and eat more home-cooked food. I’ll also try to stay active by doing some exercise every day.
Mother : Exercise is very important. Even if it’s just a little bit of walking or yoga in the mornings, it’ll help keep you fit and keep stress at bay.
You : Definitely. I’ll also make sure I drink enough water, especially with all the studying and activities I’ll have.
Mother : Water is key! Staying hydrated helps with focus and energy. Also, try to keep a routine, and don’t skip meals. It’s easy to get caught up with college work and forget to eat.
You : I’ll make sure I eat three proper meals a day. I’ll also try to get good sleep, even though the schedule might be busy.
Mother : Sleep is crucial. You need enough rest to concentrate on your studies and stay healthy. Make sure you don’t stay up too late studying or using your phone.
You : I’ll stick to a sleep routine. I’ll keep my phone away an hour before bed and try to unwind with a book instead.
Mother : I’m so proud of you. Remember, your health should always come first. If you ever feel stressed or unwell, don’t hesitate to reach out. I’m always here for you.
You : Thanks, Mom! I’ll take care of myself. I’ll keep you updated and come to you if I need anything.

Student : I’m in the science stream, studying physics, chemistry, and mathematics.
Lecturer : Great! For engineering, you can appear for JEE Main and JEE Advanced. These are the most popular exams. Have you considered them?
Student : Yes, I have heard of JEE. Are there any other exams for engineering?
Lecturer : Apart from JEE, there are state-level exams like BITSAT, VITEEE, and private university exams. They also offer great opportunities for engineering admissions.
Student : What if I want to go into medicine? Are there exams for that?
Lecturer : Yes, for medical fields, the NEET exam is the key. It’s required for MBBS, BDS, and other medical courses in India. There are also exams for pharmacy like GPAT.
Student : Are there exams for law and management as well?
Lecturer : For law, the CLAT is the most common, and there’s also AILET for Delhi University. For management, the CAT exam is widely recognized, but you can also consider MAT and XAT.
Student : That’s really helpful! Are there any other exams related to government jobs?
Lecturer : Yes, after intermediate, you can take exams like NDA for defence, and SSC for various government jobs. UPSC is for civil services, but that’s after graduation.

That sounds interesting! Which topic are you referring to, and how do you think a field trip would enhance your learning experience?
Student : We’ve been studying environmental science, and there’s a nature reserve nearby that would offer hands-on experience. Visiting it would help us understand the concepts of biodiversity and conservation better.
Principal : I see. It’s always great to see students eager to learn outside the classroom. Have you discussed this with your teacher? What are their thoughts on the trip?
Student : Yes, we’ve spoken to our teacher about it, and they’re fully supportive. They think it’s a fantastic idea and would even help in organizing the trip.
Principal : That’s good to hear. Organizing a field trip involves quite a bit of planning. Do you have a proposed date, and have you considered the logistics like transportation and safety measures?
Student : We’re thinking of going next month. As for transportation, we could hire a bus, and our teacher has volunteered to stay with us throughout the trip to ensure safety.
Principal : It sounds like you’ve thought this through. I’ll need to consult with the administration to ensure we have the budget and necessary approvals. I’ll also need to see how many students will be attending.
Student : Thank you! We’re hoping for a group of about 30 students, and we’re willing to contribute a small fee to cover the expenses.

Question 5.
Create a conversation between two brothers discussing the etiquette to be followed in social media.
Answer:
Brother 1 : Hey, have you seen how some people post on social media? It’s getting out of hand sometimes.
Brother 2 : I know, right? It’s like some people forget there’s a called privacy. They share everything – personal fights, drama. It’s like they want everyone to their business.
Brother 1 : Exactly! And then they wonder why people comment negatively. It’s important to think before posting. It’s about maintaining respect and not oversharing.
Brother 2 : Yeah, it’s all about boundaries. It’s okay to share the good stuff, like family events or achievements, but you don’t need to air dirty laundry or make everything a public spectacle.
Brother 1 : Definitely Also, I think people should be careful about how they comment on others’ posts. It’s so easy to misinterpret something online, and one wrong comment can lead to a lot of drama.
Brother 2 : For sure. Always think before typing. It’s better to avoid arguments, especially if it’s just over something trivial. Plus, there’s no “tone of voice” online, so things can come off harsher than intended.
Brother 1 : True. And don’t get me started on tagging people in pictures without asking first. That’s a major no-no.
Brother 2 : I agree. Not everyone wants to be tagged in everything. It’s always best to ask before posting a photo of someone else, especially if it’s a more private moment.
Brother 1 : Also, what about those posts where people constantly promote products or brands? I mean, it’s fine, but it’s just too much sometimes. Social media is for connecting, not for constant advertising.
Brother 2 : Yeah, it’s like, if someone is constantly selling stuff, it feels less personal and more like a business page. You have to balance it out, keep it friendly and authentic:
Brother 1 : Exactly. Social media should be fun and respectful. It’s about sharing experiences and ideas, not just putting on a show or trying to make money off your followers.
Brother 2 : Totally. If everyone followed these basic rules, social media could be a much better place. It’s all about being mindful of others and staying true to yourself.
Brother 1 : Couldn’t agree more. Let’s keep it positive, keep it respectful!

Question 6.
Create a conversation between you and your lecturer about the pros and cons of AI.
Answer:
Student : Good afternoon, Professor. I’ve been reading a lot about AI recently and wanted to ask your opinion on it. What do you. think are the main benefits?
Lecturer : Good afternoon! AI certainly has many advantages. For one, it can help improve efficiency. Tasks that once took a lot of time can be automated, allowing us to focus on more complex issues. It’s also being used in fields like healthcare to assist in diagnosis and treatment plans.
Student : That’s true. AI has really revolutionized healthcare. But do you think there are any risks associated with it?
Lecturer : Definitely. One of the biggest concerns is job displacement. As more tasks get automated, some workers could lose their jobs. There’s also the issue of privacy; with AI systems collecting vast amounts of data, there’s potential for misuse.
Student : I can see how privacy could be a major concern. With all the data being collected, it feels like personal boundaries are being blurred. Do you think AI could become too advanced for us to control?
Lecturer : It’s a possibility. If AI systems become more autonomous, they could act in ways we don’t anticipate. It’s important to set strict regulations to ensure that AI development stays within ethical and safe boundaries. Without oversight, we risk losing control.
Student : That’s definitely something to consider. But do you think AI can improve our lives in other ways, like in education or daily tasks?
Lecturer : Absolutely. In education, AI can personalize learning- experiences. It can help create customized learning paths for students, identify where they’re struggling, and provide real-time feedback. It’s also used in smart home devices to automate tasks like managing energy or controlling the environment.
Student : That sounds pretty helpful. On the flip side, though, there’s also the concern of over-reliance on AI. Could people become too dependent on it?
Lecturer : Yes, that’s another valid concern. Over-dependence could lead to a loss of critical thinking or problem-solving skills. It’s crucial that we strike a balance between using AI for efficiency and maintaining our own abilities to think and act independently.
Student : I think you’re right. It’s about balance. On a positive note, could AI help us solve global problems, like climate change or poverty?
Lecturer : Yes, AI has the potential to be a powerful tool in addressing global challenges. It can analyze vast amounts of data to predict climate patterns, optimize energy usage, or even improve agricultural methods, However, like with any tool, it depends on how we use it.
Student : So, it really comes down to how we manage and direct AI, doesn’t it? The pros and cons are both significant, but with the right control, we could harness its power for good.
Lecturer : Exactly. If we approach AI responsibly, it can offer incredible benefits. It’s up to us, as a society, to ensure that it’s used ethically and that its development is aligned with the greater good.

Letter to the Editor about the problem of plastic pollution.
Answer:
H.No. 12/334
Lake View Colony, Chennai – 600 042

The Editor
The Hindu, Chennai

Dear Sir / Madam,

Subject : Increasing problem of plastic pollution

I am a concerned citizen of this city. Through the columns of your respected newspaper, I would like to draw the attention of the public and the authorities concerned to the growing problem of plastic pollution in our city.

Plastic waste is seen everywhere. It blocks drains and makes our surroundings dirty. Rivers and lakes are getting polluted. Many stray animals eat plastic and fall sick or die. Though the government has banned single-use plastic, the rules are not properly followed. Many people still use plastic carelessly.

If this problem continues, it will cause serious damage to our environment. Therefore, the authorities should strictly enforce the ban on plastic. They should also conduct awareness programmes to educate people. Citizens must cooperate by using cloth bags and other eco-friendly materials.

I hope the authorities concerned will take immediate action to control this problem.

Yours sincerely

Answer:
[Your City/Town]
[Date]

Dear [Friend’s Name],

I hope this letter finds you in good health and high spirits. I’m writing to tell you all about the incredible educational tour I just returned from. Last week, our college organized a trip to Hyderabad for our class, and it was truly an unforgettable experience.

We traveled together with our teachers, and the atmosphere was full of excitement from the moment we boarded the bus. Our first stop was the Salar Jung Museum. I was amazed by the massive collection of artifacts; seeing the famous veiled Rebecca statue and the musical clock in person was a highlight. It felt like walking through centuries of global history in just a few hours.

We also visited the iconic Charminar. Climbing up to see the view of the bustling Laad Bazar below gave me a real sense of the city’s vibrant heritage and architectural brilliance. To balance the historical side of the trip, we spent time at the Birla Science Museum. The interactive exhibits and the Dinosaurium were fascinating – it made complex scientific concepts much easier to understand.

This trip was more than just a sightseeing tour. I learned so much about the Nizams’ culture, the importance of preserving our national heritage, and even some new scientific facts. Beyond the learning, the time spent bonding with classmates and teachers away from the classroom made the journey even more special.

I really wish you could have been there with us. I’ve taken plenty of photos and can’t wait to show them to you when we meet!

Warm regards,

[Your Address]
[City, State, Zip Code]
[Date]

Dearest [Brother/Sister’s Name],

I hope this letter finds you in great health and spirits. Everything is going well here, though my schedule has become quite busy as I navigate my final year of Intermediate studies. Since you have always been my guide and confidant, I wanted to share my thoughts with you regarding my future career plans.

After much reflection and research, I have decided that I want to pursue a career in Digital Design and Educational Technology.

The reason I chose this path is my growing fascination with how visual information can simplify complex learning. I’ve realized that while textbooks are essential, many students struggle to grasp difficult concepts through text alone. I want to build a career where I can create high-quality visual aids, like 3D mind maps and structured diagrams, to make education more engaging and accessible for everyone. Seeing a difficult topic become clear through a well-designed visual gives me a great sense of accomplishment.

I am fully aware that reaching this goal requires significant effort. To achieve this, I have started focusing on improving my technical skills alongside my academic subjects. I am dedicating time to learning advanced graphic design software and studying the principles of visual communication. I plan to maintain a strict study schedule to ensure I score well in my board exams while also building a portfolio of my creative work.
Your journey has always inspired me to aim high, and I hope to make you proud by turning this passion into a successful profession. I would love to hear your thoughts and any advice you might have for me as I take these next steps.

Please convey my regards to everyone at home. I look forward to hearing from you soon.

With lots of love,

Reviewing AP Inter 2nd Year Zoology Study Material Chapter 5 Evolution Questions and Answers can help students prepare confidently for exams.

AP Inter 2nd Year Zoology 5th Lesson Evolution Questions and Answers

IV. Very Short Answer Questions

Question 1.
What is Convergent evolution?
Answer:
Convergent evolution is the evolutionary process in which unrelated organisms independently develop similar structures or adaptations because they live under similar environmental conditions, even though they do not share a recent common ancestor. Example: Wings of birds and insects.

Question 2.
What are Mutations?
Answer:
Mutations are alterations in the DNA sequence that result in changes in an organism’s genotype and may also affect its phenotype.

Question 3.
What is the significance of Coelacanth fish?
Answer:
The significance of Coelacanth lies in the following:

1. It is regarded as a “living fossil” because it was believed to be extinct but was discovered alive in 1938.
2. It provides valuable evidence for evolution, particularly the transition from fishes to amphibians due to its lobe-finned structure.

Question 4.
What is founder effect?
Answer:

1. Founder effect is a form of genetic drift in which a new population is established by a small group of individuals.
2. As a result, the new population shows reduced genetic diversity and different allele frequencies compared to the original population.

Question 5.
What are the two key concepts of Darwin’s theory of Evolution?
Answer:
The two fundamental ideas of Darwin’s theory are:

1. Branching Descent: All organisms originate from common ancestors and gradually diversify over time, producing new species and evolutionary branches.
2. Natural Selection: Organisms possessing advantageous variations are better adapted to their environment. They survive and reproduce successfully, passing these favourable traits to future generations.

V. Short Answer Questions

Question 1.
Explain the Hardy-Weinberg principle.
Answer:
The Hardy-Weinberg principle states that allele frequencies within a population remain constant from one generation to the next when no evolutionary forces act upon it. This stable condition is known as genetic equilibrium.

1. Mathematical Expression: For a gene with two alleles, A and a:

• If p represents the frequency of allele A and q represents the frequency of allele a, then p + q = 1
• Frequency of homozygous dominant individuals (AA) = p²
• Frequency of homozygous recessive individuals (aa) = q²
• Frequency of heterozygous individuals (Aa) = 2pq
• Therefore, p² + 2pq + q² = 1

2. Evolutionary Significance: Any deviation from the expected Hardy-Weinberg frequencies indicates that evolutionary changes are occurring within the population.

3. Factors Disturbing Genetic Equilibrium :

• Gene migration (Gene flow): Movement of alleles into or out of a population.
• Genetic drift: Random fluctuations in allele frequencies.
• Mutation: Sudden changes in genetic material.
• Genetic recombination: Formation of new gene combinations during gamete production
• Natural selection: Differential survival and reproduction of individuals with favourable traits.

Question 2.
Give an account of the evolution of Man.
Answer:

1. Human evolution is a gradual process that traces the development of modern humans from primitive primate ancestors over millions of years.
2. Early primates such as Dryopithecus and Ramapithecus (about 15 million years ago) were hairy, ape-like forms. Dryopithecus was more ape-like, whereas Ramapithecus showed more human-like characteristics.
3. Later, Australopithecus (around 3-4 million years ago) appeared in East Africa. They walked upright, used simple tools, and mainly fed on fruits.
4. Homo habilis was the first human-like species. It possessed a brain capacity of approximately 650 – 800 cc and is called the “handyman” because of its tool-making ability.
5. Homo erectus (about 1.5 million years ago) had a larger brain of nearly 900 cc, walked completely upright, used fire, and probably consumed meat.
6. Neanderthal man (100,000 – 10,000 years ago) had a brain size of about 1400 cc. They used animal skins for clothing and practiced burial of the dead, indicating social organization.
7. Finally, Homo sapiens evolved in Africa during the last Ice Age (about 75,000 – 10,000 years ago) and later spread across the globe, developing advanced language, culture, and intelligence.

Question 3.
Explain Miller’s experiment of chemical evolution.
Answer:

1. Miller designed a closed experimental setup containing methane (CH₄), ammonia (NH₃), hydrogen (H₂), and water (H₂O) to simulate primitive Earth conditions.
2. Water was heated to generate water vapour, while electric sparks were passed through the gaseous mixture to imitate lightning.
3. The steam mixed continuously with methane, ammonia, and hydrogen gases inside the apparatus.
4. The electrical discharges supplied energy, and the vapours were cooled and condensed repeatedly, creating a continuous cycle.
5. After several days, a dark brown coloured solution accumulated in the system.
6. Analysis revealed the presence of organic molecules, including amino acids such as glycine and alanine, which are basic building blocks of proteins.
7. The experiment demonstrated that essential organic compounds can be synthesized from non-living substances under primitive Earth conditions, supporting the theory of chemical evolution.

Question 4.
Explain adaptive radiation with suitable examples.
Answer:

1. Adaptive radiation is an evolutionary phenomenon in which multiple species evolve from a common ancestor within a specific geographical region and adapt to different ecological niches.
2. These species arise from a shared ancestral stock and gradually diversify to exploit different habitats and resources.
3. A classic example is Darwin’s finches, where various finch species evolved from a common seed-eating ancestor and developed distinct beak types suited to different food habits.
4. Another example is the Australian marsupials, which evolved from a common ancestral form and adapted to a wide range of habitats in Australia.
5. Under similar environmental pressures, some organisms may evolve comparable adaptations, as seen in placental mammals and marsupials such as the placental wolf and Tasmanian wolf.

Question 5.
Explain the homologous and analogous organs with suitable examples.
Answer:
I) Homologous Organs: Homologous organs are structures that share a common origin and basic structural plan but perform different functions. They are evidence of divergent evolution, where related organisms evolve in different directions to meet different environmental demands.

Examples:

• Forelimbs of whale, bat, cheetah, and human-same structural pattern but different functions such as swimming, flying, running, and grasping.
• Hearts or brains of vertebrates,
• Thorns of Bougainvillea and tendrils of Cucurbita.

II) Analogous Organs: Analogous organs are structures that differ in origin and anatomy but perform similar functions.
They arise through convergent evolution, where unrelated organisms independently develop similar adaptations.

Examples:

• Wings of birds and butterflies → same function (flight) but different structure.
• Eyes of octopuses and mammals → same function (vision) but different evolutionary origin.
• Flippers of penguins and dolphins.
• Sweet potato (root) and potato (stem) → both functioning as food storage organs.

Question 2.
Describe the steps involved in DNA fingerprinting technology.
Answer:
DNA Fingerprinting-Procedure:

1. Collection of DNA: DNA is isolated from sources such as blood, saliva, semen, hair roots, or tissues. If needed, DNA is amplified using cloning techniques or PCR.
2. Fragmentation of DNA: DNA is cut into smaller fragments at specific locations using restriction endonucleases.
3. Separation of DNA Fragments: The DNA fragments are separated by agarose gel electrophoresis. Smaller fragments move faster and travel farther through the gel.
4. Denaturation: The double-stranded DNA is converted into single strands using heat or alkaline chemicals.
5. Blotting: DNA fragments are transferred from the gel onto a nylon membrane. This transfer process is known as Southern blotting.
6. Hybridization with DNA Probes: Radioactively labelled DNA probes complementary to the target sequences are added. These probes bind to matching DNA fragments.
7. Probe Hybridization: After binding occurs, excess probes are removed, leaving only DNA- probe hybrids on the membrane.
8. Autoradiography and DNA Fingerprint Formation: The membrane exposed to photographic film. Radioactive signals produce characteristic bands that form the individual’s DNA fingerprint.

VI. Long Answer Questions

Question 1.
Why is the Human Genome Project called a mega project?
Answer:
The Human Genome Project (HGP) is regarded as a mega project because of its enormous scope, high expenditure, long duration, and the vast amount of genetic information it generated. It demanded worldwide cooperation, significant financial support, and sophisticated computational technologies.

The following points explain why it is considered a mega project:
1. Huge Number of Base Pairs: The human genome consists of nearly 3 × 10⁹ base pairs, making it extremely large and complex. Identifying and sequencing every base pair across all chromosomes was an enormous scientific challenge unlike any previous genetic research.

2. Enormous Financial Investment: The project required substantial funding. If sequencing a single base pair cost about $3, the estimated expenditure for the entire project would have been approximately $9 billion. Such an extraordinary financial commitment makes it a true mega project.

3. Extended Time Period: Completing a project of this scale required careful planning and many years of work. Initiated in 1990, the Human Genome Project was successfully completed in 2003, taking nearly 13 years.

4. Massive Data Generation and Bioinformatics: The project produced an enormous volume of genetic data. If this information were printed, assuming each book contained 1,000 pages with 1,000 letters per page, nearly 3,300 books would be needed to store the genetic information from a single human cell. Managing, storing, and analyzing such data required advanced computer systems, leading to the development of the field of Bioinformatics.

5. Global and Multidisciplinary Collaboration: A project of this magnitude could not be accomplished by a single nation or institution. It involved international cooperation under the coordination of the U.S. Department of Energy and the National Institutes of Health (NIH), with major contributions from the United Kingdom, Japan, France, Germany, and China. Scientists from diverse fields, including biology, computer science, engineering, and mathematics, worked together to achieve its objectives.

6. Significant Scientific and Medical Impact: The Human Genome Project revolutionized biological and medical research. It enabled scientists to identify the genetic basis of numerous diseases, improved preventive healthcare, and supported the development of personalized medicine and pharmacogenomics, greatly benefiting human health and scientific advancement.

Question 2.
Write an essay on DNA Fingerprinting.
Answer:
1. DNA Fingerprinting: DNA fingerprinting is a technique used to identify individuals based on the unique pattern of their DNA. Since every person (except identical twins) possesses a distinct DNA profile, this method is highly reliable for identification.

• DNA fingerprinting is also referred to as DNA typing or genetic fingerprinting.
• It is extensively used in forensic investigations, paternity and maternity testing, and individual identification.
• DNA samples can be collected from blood, saliva, semen, hair roots, tissues, bones, or other biological materials.
• Although more than 99% of the nearly 3 billion base pairs in human DNA are identical, the remaining variations make each individual unique.
• Except for identical twins, no two individuals possess the same DNA sequence.
• These variable DNA regions are known as Restriction Fragment Length Polymorphisms (RFLPs) or Variable Number Tandem Repeats (VNTRs).
• The pattern of VNTRs differs from one individual to another, making them useful for identification.
• The DNA fingerprinting technique was developed by Sir Alec Jeffreys while studying the myoglobin gene.

2. Procedure of DNA Fingerprinting. DNA fingerprinting involves the following steps:

Isolation of DNA: DNA is extracted from biological samples such as blood, saliva, semen, hair roots, or tissues. If required, the extracted DNA is amplified using cloning or DNA amplification techniques.

Digestion of DNA: The isolated DNA is cut into smaller fragments at specific recognition sites using restriction endonuclease enzymes.

Separation of DNA Fragments by Gel Electrophoresis: The DNA fragments are loaded onto an agarose gel and subjected to an electric field. Smaller DNA fragments migrate faster and travel farther through the gel than larger fragments.

Denaturation of DNA: The double-stranded DNA is separated into single strands using alkaline chemicals or by heating.

Southern Blotting: The separated DNA fragments are transferred from the gel onto a nylon membrane by placing the membrane over the gel and allowing absorbent paper to draw the DNA onto it. This transfer process is known as Southern blotting.

Identification Using DNA Probes: Radioactively labelled DNA probes, which are complementary to specific DNA sequences, are added. These probes bind to the matching DNA fragments through hydrogen bonding.

3. Hybridisation with DNA Probe: After hybridisation, the excess probes are washed away. The nylon membrane containing the DNA-probe hybrids is then covered with photographic (X-ray) film.

4. Development of the DNA Fingerprint: The radioactive probes expose the photographic film, producing dark bands that correspond to specific DNA fragments. The unique arrangement of these bands forms the DNA fingerprint of an individual.

5. Applications of DNA Fingerprinting :

• Forensic Science: Used to identify criminals and establish the identity of suspects.
• Medico-Legal Cases: Helps determine biological relationships such as paternity and maternity.
• Anthropological Research: Assists in studying human evolution, ancestry, and migration patterns.
• Pedigree Analysis: Used to trace inheritance patterns across generations.
• Taxonomy: Helps in studying phylogenetic relationships among organisms.
• Wildlife Conservation: Assists in maintaining genetic records and conserving endangered species.

V. Short Answer Questions 

Question 1.
Explain sex determination in human beings.
Answer:
Sex determination in humans:

1. Humans exhibit the XX-XY type of sex determination.
2. Out of the 23 chromosome pairs, 22 pairs are autosomes and 1 pair is made up of sex chromosomes.
3. Females possess the karyotype 44XX, while males possess 44XY.
4. Females produce only one type of gamete carrying the X chromosome, whereas males produce two types of sperms carrying X or Y chromosomes.
5. Female gametes contain 22A+X; male gametes contain either 22A+X or 22A+Y.
6. Fertilization of the ovum by an X-bearing sperm results in a female child (44XX).
7. Fertilization by a Y-bearing sperm produces a male child (44XY).
8. Therefore, the type of sperm that fertilizes the ovum determines the sex of the child.
9. Each pregnancy has an equal 50% chance of producing either a male or female offspring.

Question 2.
Mention any two autosomal Mendelian disorders and write their symptoms.
Answer:
1. Haemophilia:

• Haemophilia is a sex-linked recessive genetic disorder that affects the blood’s ability to clot properly.
• Individuals suffering from this condition experience prolonged and excessive bleeding even from minor cuts or injuries.
• The deficiency of specific clotting factors leads to difficulty in stopping bleeding.
• This disorder is more commonly observed in males, as they have only one X chromosome.

2. Colour Blindness:

• Colour blindness is a sex-linked genetic disorder in which an individual has difficulty distinguishing between certain colours, especially red and green.
• It occurs due to defects in the cone cells of the retina responsible for colour vision.
• This condition does not affect overall vision but impairs the ability to identify colours correctly.
• It is also more frequently found in males than in females.

Question 3.
Describe male heterogamety and female heterogamety method of sex deter¬mination with suitable examples.
Answer:
A. Male Heterogamety: In this system, males produce two types of gametes while females produce only one type. It occurs in two forms:
1. XX-XO Type :

• Found in bugs, grasshoppers, and cockroaches.
• Female genotype: AAXX and produces only AX gametes.
• Male genotype: AAXO and produces AX and AO gametes in equal proportions.
• The sperm determines the sex of the offspring.

2. XX-XY type:

• Found in humans and Drosophila.
• Female genotype: AAXX and produces only AX gametes.
• Male genotype: AAXY and produces AX and AY gametes.
• The sperm carrying X or Y chromosome determines the sex of the offspring.

B. Female Heterogamety: In this type, females produce two kinds of gametes, while males produce only one type. It occurs in two forms:
1. ZO-ZZTvpe:

• Seen in moths and some butterflies.
• Males produce only AZ gametes.
• Female produces AZ and AO ova.
• The ovum determines the sex of the offspring.

2. ZW-ZZ Type:

• Found in certain fishes, reptiles, and birds.
• Female produces AZ and AW ova.
• Male produces only AZ sperms.
• The ovum carrying Z or W chromosome decides the sex of the progeny.

Question 4.
Explain the haplodiploid System of Sex determination in honey bees.
Answer:
The haplodiploid mechanism of sex determination in honey bees depends on the number of chromosome sets present.
1. Females (Queen and Workers):

• Females develop from fertilized eggs formed by the fusion of sperm and ovum.
• They are diploid (2n = 32 chromosomes).

2. Males (Drones) ;

• Males arise from unfertilized eggs through parthenogenesis.
• They are haploid (n = 16 chromosomes).

3. Sperm Formation: Drones produce sperms through mitotic divisions.
4. Family Relationship:

• Drones have no father because they originate from unfertilized eggs.
• However, they possess a grandfather and can have grandsons.

Thus, in honeybees, sex is determined by chromosome number (haploid or diploid) rather than by sex chromosomes.

Question 5.
What is Thalassemia? Explain the two types of Thalassemia in detail.
Answer:

1. Thalassemia is an autosomal recessive blood disorder inherited when both parents carry the defective gene.
2. It results from mutation or deletion of genes responsible for globin chain synthesis.
3. Reduced globin production leads to abnormal haemoglobin formation and causes anaemia.

Types of Thalassemia :
a) Alpha (α) Thalassemia:

• Characterized by reduced synthesis of α-globin chains.
• Controlled by HBA1 and HBA2 genes located on chromosome 16.
• Since four α-globin genes are present (two from each parent), severity depends on the number of affected genes.
• Greater gene deletions result in a more severe condition.

b) Beta (β) Thalassemia :

• Characterized by reduced synthesis of β – globin chains.
• Controlled by the HBB gene located on chromosome 11.
• The disorder develops when one or both β – globin genes are mutated.

VI. Long Answer Questions

Question 1.
Write an essay on common genetic disorders in humans.
Answer:
Common Genetic Disorders: Many human diseases arise due to abnormalities in genes or chromosomes. These disorders are broadly classified into:
I. Mendelian Disorders II. Chromosomal Disorders.
1. Mendelian Disorders: These disorders follow Mendelian inheritance patterns and are usually caused by mutations in a single gene (monogenic disorders). They may be autosomal or sex-linked. Examples: Haemophilia, Sickle-cell anaemia, Phenylketonuria, Colourblindness, Thalassemia, Cystic fibrosis, Albinism, etc.

1. Haemophilia:

• Haemophilia is commonly known as a bleeding disorder because blood fails to clot normally after injury.
• Haemophilia A results from deficiency of clotting factor VIII.
• Haemophilia B results from deficiency of clotting factor IX.
• Both A and B are X-linked recessive disorders.
• Haemophilia C is an autosomal recessive disorder caused by deficiency of clotting factor XI.
• Haemophilia A and B may skip generations.
• The disorder is rare in females because two recessive genes are required.
• It is more frequently observed in males.

2. Sickle-cell Anaemia:

• Sickle-cell anaemia is an autosomal recessive disorder caused by a defective gene located on chromosome 11.
• It is expressed in the homozygous condition.
• Symptoms include weakness, pain, organ damage due to internal bleeding, and sometimes paralysis.
• The disorder results from the substitution of glutamic acid by valine at the sixth position of the beta-globin chain.
• Red blood cells become sickle-shaped and rigid.
• These cells may block capillaries while passing through them.
• Heterozygous individuals may occasionally show mild symptoms but possess increased resistance to malaria.

3. Phenylketonuria (PKU):

• Phenylketonuria was first described by A. Foiling.
• It is an autosomal recessive metabolic disorder.
• The responsible gene is located on chromosome 12.
• Patients lack the enzyme phenylalanine hydroxylase, which converts phenylalanine into tyrosine.
• As a result, phenylalanine is converted into phenylpyruvic acid.
• Accumulation of phenyl ketones may lead to mental retardation.

4. Colour Blindness:

• Colour blindness is an X-linked recessive disorder.
• Protanopia refers to red colour blindness.
• Deuteranopia refers to green colour blindness.
• Affected individuals cannot distinguish red from green colours.
• The Ishihara colour test is commonly used for diagnosis.
• Tritanopia is associated with blue colour blindness and is autosomal in nature.

5. Thalassemia:

• Thalassemia is an autosomal recessive disorder affecting haemoglobin synthesis.
• α-globin genes are located on chromosome 16.
• β – globin genes are located on chromosome 11.
• Defective globin synthesis damages red blood cells.
• RBC count decreases, leading to anaemia.

6. Cystic Fibrosis:

Question 2.
Write an essay on sex determination;
Answer:
Chromosomal Theory of Sex Determination: In most animals, sex is determined by a pair of chromosomes known as sex chromosomes or allosomes.
The two major sex chromosomes are the X chromosome and Y chromosome.
There are two major systems of chromosomal sex determination:
I. Male Heterogametic Method
II. Female Heterogametic Method
Male Heterogametic Method: In this system, males produce two kinds of gametes, while females produce only one type.

1. XX-XO Type:

• Found in grasshoppers, bugs, and cockroaches.
• Females possess two X chromosomes, whereas males have only one X chromo¬some.’
• The unpaired X chromosome determines maleness.
• Female karyotype is AAXX and male karyotype is AAXO.
• All ova contain the AX complement.
• Sperms are of two types:

1. 50% contain AX
2. 50% contain AO

• The sex of the offspring depends on the sperm that fertilizes the ovum.

2. XX-XY Type:

• Found in humans and Drosophila.
• Females are homogametic with genotype AAXX and produce only AX ova.
• Males are heterogametic with genotype AAXY. homo sapiens
• Half the sperms carry AX, and the other half carry AY.
• The fertilizing sperm determines the sex of the offspring.
• Fertilization by AX sperm produces a female child (AAXX).
• Fertilization by AY sperm produces a male child (AAXY).

II. Female Heterogametic Method: In this type, females produce two kinds of ova, while males produce only one type of sperm. Two forms are recognized:
1. ZO – ZZ Type:

• Found in moths (Fumea) and certain butterflies.
• Females are heterogametic with one Z chromosome.
• Males are homogametic with ZZ chromosomes
• Female karyotype is AAZO and male karyotype is AAZZ.
• The ovum determines the sex of the of Spring.
• Fertilization of an AO ovum produces a female.
• Fertilization of an AZ ovum produces a male.

2. ZW-ZZ Type:

• Found in birds, reptiles, and some fishes.
• Females are heterogametic with ZW chromosomes.
• Males are homogametic with ZZ chromosomes.
• Female karyotype is AAZW and male karyotype is AAZZ.
• The ovum that gets fertilized determines the sex of the offspring.
