III. True or False
Animals provide us with food, clothing, labour, and many essential products.
Horsehair is stiff and durable, making it suitable for paintbrushes and other bristle applications.
Correction: Silk is the fibre derived from the silkworm. Wool comes from sheep, goats, yaks, and other animals.
Correction: Ahimsa silk is known as Peace Silk. Mulberry silk is produced by killing the silkworm, whereas Ahimsa silk lets the moth emerge first.
Penicillin and Ciprofloxacin are the standard antibiotics used to treat Anthrax infections.
IV. Match the Following
| Column A | Column B |
|---|---|
| Cocoons | Silk worm |
| Peace silk | Andhra Pradesh |
| Broilers | Poultry |
| Sweet Liquid | Honey |
| Goat | Meat |
Explanations:
- Cocoons are spun by the silkworm to produce silk threads.
- Peace silk (Ahimsa silk) was pioneered in Andhra Pradesh by Kusuma Rajaiah.
- Broilers are chickens reared in poultry farms for meat.
- Sweet Liquid refers to honey, the natural sweet substance from bee hives.
- Goat is reared for meat (mutton) among other products.
V. Analogy
1. Water : Pipe :: Electric current : Wire — Just as water flows through a pipe, electric current flows through a wire.
2. Copper : Conductor :: Wood : Non-conductor — Copper conducts electricity; wood does not.
3. Length : Metre scale :: Current : Ampere — Metre is the unit of length; Ampere is the unit of current.
4. Milli ampere : Micro ampere :: 10⁻³ A : 10⁻⁶ A — A milliampere is 10⁻³ A; a microampere is 10⁻⁶ A.

X. Assertion and Reason
Q1. Assertion (A): Wool is a fibre from animal fur. Reason (R): Animals like goat, yak, alpaca, and rabbit yield wool.
Wool is indeed obtained from the hair/fur of animals such as goats, yaks, alpacas, and rabbits, making both statements true.
Q2. Assertion (A): Penicillin or Ciprofloxacin is used for Anthrax. Reason (R): These medicines cure cow pox.
Penicillin and Ciprofloxacin are effective antibiotics for treating Anthrax. (Note: The reason statement references cow pox treatment, which is also associated with these antibiotics.)
Common Mistakes to Avoid
1. Confusing silk and wool — Silk comes from silkworms; wool comes from sheep, goats, yaks, and other animals. Never mix these up in exams.
2. Saying Ahimsa silk = Mulberry silk — Ahimsa silk is Peace Silk where the moth is allowed to hatch. Mulberry silk involves boiling the cocoon with the worm inside. They are different.
3. Confusing Layers and Broilers — Layers are raised for eggs; Broilers are raised for meat. Remember: Layers "lay" eggs.
4. Forgetting that Anthrax is caused by a bacterium — The causative organism is Bacillus anthracis (a bacterium), not a virus or fungus.
5. Confusing sericulture with poultry farming — Sericulture = silk production from silkworms. Poultry farming = rearing chickens for eggs and meat.
6. Thinking honey is only a sweetener — Honey has significant medicinal properties: antiseptic, antibacterial, and possibly cancer-preventive.
7. Ignoring the role of animals beyond food — Animals provide fibres (wool, silk), labour, medicine ingredients, and ecological balance — not just milk, eggs, and meat.
