Answers
Explanation:
1. Silkworms weave themselves a covering called a cocoon, to protect them while they transform into moths. The caterpillar produces a sticky liquid from special glands next to its mouth. The liquid sets into a single long thread that winds around and around the caterpillar.
2. Beekeepers harvest it by collecting the honeycomb frames and scraping off the wax cap that bees make to seal off honey in each cell. Once the caps are removed, the frames are placed in an extractor, a centrifuge that spins the frames, forcing honey out of the comb.
3. It was used for both the lac insect (because of their enormous number) and the scarlet resinous secretion it produces. This resin has been used for making traditional and tribal bangles, and still used as sealing wax by the India Post.
4. The common housefly can transmit the pathogens that cause shigellosis, typhoid fever, E. coli, and cholera. The disease-causing agents can either be transmitted by the body hairs or by the tarsi which are transmitted to food or surfaces when the fly lands.
