Answer:
The white hair of a polar bear is an example of adaptation.
Explanation:
Adaptation allows organisms to adjust to their surroundings so that they can survive. Polar bears live in the Arctic region, which is one of the coldest places in our planet. They have sharp teeth and their ears are small to reduce the heat loss. They have a thick coat of insulated fur, which insulates their thick layer of body fat and keeps them warm. They have large paws, that are covered by fur which protects them from sinking in the snow and also provides a good grip on ice. Their coat of white fur helps them to hide from their prey by providing a camouflage in Arctic environments.
