Q.17 Write any three characteristics of an ideal fuel.3
Answer: Three characteristics of an ideal fuel are:
1. It should have a high calorific value.
2. It should be cheap and easily available.
3. It should not leave behind any undesirable or harmful residues/gases after burning.
1. It should have a high calorific value.
2. It should be cheap and easily available.
3. It should not leave behind any undesirable or harmful residues/gases after burning.
Q.18 What is Red Data Book?3
Answer: Red Data Book is the sourcebook which keeps a record of all the endangered animals and plants (species that are facing a high risk of extinction). It is maintained internationally to help in their conservation.
Q.19 What is reproduction? What are the methods of reproduction in animals?3
Answer: Reproduction is the biological process by which living organisms produce new individuals of the same kind. It is essential for the continuation of a species. In animals, there are two modes of reproduction: 1. Sexual reproduction (involves two parents), 2. Asexual reproduction (involves a single parent).
Q.20 What is menstruation? Explain.3
Answer: In females, the ovaries release one egg every month. The uterus prepares itself to receive a fertilized egg by thickening its inner lining. If fertilization does not occur, the thickened lining of the uterus, along with its blood vessels, sheds off through the vagina. This bleeding in women is called menstruation. It occurs once in about 28 to 30 days.
Q.21 A blacksmith hammers a hot piece of iron while making a tool. How does the force due to hammering affect the piece of iron?3
Answer: The blacksmith applies muscular force while hammering the hot piece of iron. This force changes the shape of the iron piece, flattening it into a sheet or giving it the desired shape of the tool without breaking it.
Q.22 Can you store lemon pickle in an aluminium utensil? Explain.3
Answer: No, we cannot store lemon pickle in an aluminium utensil. Lemon pickle contains citric acid. This acid reacts with the aluminium metal to produce toxic salts and hydrogen gas, which spoils the pickle and makes it unfit and harmful for human consumption.
Long Answer Type Questions (Q.23 to 26)
Instructions – Answer the following questions in 70-80 words. Each question carries 5 marks.
Q.23 What are antibiotics? What precautions must be taken while taking antibiotics?5
Answer: Medicines produced by certain microorganisms (like bacteria and fungi) that kill or stop the growth of disease-causing microorganisms are called antibiotics (e.g., Penicillin, Streptomycin).
Precautions:
1. Antibiotics should be taken only on the advice of a qualified doctor.
2. One must finish the entire course prescribed by the doctor, even if they feel better.
3. Antibiotics should not be taken unnecessarily, as they may kill the beneficial bacteria in the body.

Q.24 Explain why sliding friction is less than static friction.5
Answer: Friction is caused by the interlocking of irregularities in the two surfaces in contact. When an object is at rest, the irregularities on its surface have enough time to strongly lock into the irregularities on the floor, resulting in high static friction.
However, when the object is already sliding over the surface, the contact points on its surface do not get enough time to lock firmly into the contact points of the floor. Because the interlocking is weaker during motion, it requires less force to keep the object moving than to start the movement. Hence, sliding friction is less than static friction.

Q.25 Describe how noise pollution is harmful to humans.5
Answer: Noise pollution is harmful to human health in several ways:
1. Lack of Sleep (Insomnia): Excessive noise disturbs sleep, leading to constant fatigue and exhaustion.
2. Health Issues: Prolonged exposure to loud noise can cause anxiety, stress, and high blood pressure (hypertension).
3. Hearing Impairment: Continuous exposure to loud sounds can cause temporary or even permanent loss of hearing (deafness).
4. Loss of Concentration: It causes distraction, making it difficult for students to focus on studies and for adults to concentrate on their work, reducing overall efficiency.
