Answer: The worm makes a cocoon around itself to protect the young one developing inside and to camouflage/protect itself from predators.

(b) Why swimming costumes are usually made up of nylon or spandex and not of cotton?

Question 10: Why are cocoons boiled in water to obtain silk?

Answer: Silk thread is obtained from the saliva of silk worms. The larva of a silk worm feeds on mulberry leaves and secretes fine threads of silk. This silk is wrapped around the worm in a cocoon. Hence the cocoons are collected and boiled in water.
