D) Incubator ii) Moulting fi) Cocoon iv) Raw silk v) thrown silk vi) Weighting vu) Exotic breeds​

Answer 1

Answer:

1. An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them.

2. shed old feathers, hair, or skin to make way for a new growth.

"the adult birds were already moulting"

3. While pupa can refer to this naked stage in either a butterfly or moth, chrysalis is strictly used for the butterfly pupa. A cocoon is the silk casing that a moth caterpillar spins around it before it turns into a pupa. ... Many butterfly pupae are cryptic and blend into their surroundings

4.The primary difference is that raw silk is silk containing a gummy substance called sericin. ... Raw silk has a nubby and rougher surface than traditional silk. The fiber used to make raw silk is shorter than traditional silk and this also contributes to its unique texture.

5. Silk throwing is the industrial process wherein silk that has been reeled into skeins, is cleaned, receives a twist and is wound onto bobbins. The yarn is now twisted together with threads, in a process known as doubling.

6. allowance or adjustment made in order to take account of special circumstances or compensate for a distorting factor.
