Answer 1

Silk is made up of a thin thread-like substance formed by the hardening of the worm's secretion.

Explanation:

• Silk is a shimmering textile comprised of the strongest natural protein fibre composed mainly of Fibroin.
• Sericulture is the process of rearing silkworms for the production of raw silk.
• The major activities of sericulture comprise food-plant cultivation  (moriculture) to feed the silkworms since they feed on mulberry leaves.
• The silkworms spin silk cocoons and we further reel the cocoons (extraction of silk filaments) for unwinding the silk filament for value-added benefits such as processing and weaving.
• One thread of silk is made of 48 silk filaments.
