Explanation:

(a)They trap a lot of air which is a

poor conductor of heat.

Animals have thick coat of hairs. These hairs help certain animals in keeping their bodies warm such as yak, sheep etc. Hairs of these animals trap a lot of air in them. Air is a poor conductor of heat i.e. it prevents the loss of heat from their bodies to cold surroundings. In this way hair of certain animals help in keeping their bodies warm.
