Answer:

1. The sticky fluid secreted by larva from its salivary glands is called fibroin.

2. The four stages in the life of a silk moth are eggs, caterpillars, cocoons, and adult moths.

3. The thread obtained in the reeling process is called raw silk.

4. Removal of fleece from the body of sheep is called shearing.

5. Sorters working in wool industry may suffer from sorter's disease.

Explanation:

1. When a caterpillar reaches the pupal stage, the larva stops feeding and begins to form a cocoon. A pair of specifically altered salivary glands termed silk glands are present in the larvae. These glands produce a clear, viscous fluid that contains the protein fibroin, which is the most important component in the creation of silk fibre.  

2. A silkworm has four stages in its life cycle. Eggs, caterpillars, cocoons, and adult moths are all included.

3. The procedure of extracting threads from the cocoon is known as reeling the silk, and the thread obtained during the reeling process is known as raw silk. Reeling is done using specific machinery that unwind the silk strands or fibres from the cocoon.

4. The procedure through which a sheep's woolly fleece is removed is called shearing. A shearer is the person who removes the wool from sheep. Each adult sheep is typically shorn once a year.

5. Sorters frequently suffer from sorter's disease, which is caused by the bacteria Anthrax.
