Answer 1

Answer:

8) Factory wastes contain acids which if untreated and discharged into water bodies will cause harm to fish and other aquatic organisms living in water bodies. Therefore, they should first be treated with basic substances to neutralise them and then discharged into water bodies.

9) We cannot survive only on raw, leafy vegetables/grass, because we cannot get all required nutrients, such as carbohydrates, proteins, lipids, vitamins and minerals, from them. Moreover raw vegetables may not be digested easily as compared to cooked vegetables.
