Answer 1

Polar bears maintain homeostasis in freezing cold weather primarily through the adaptation of their thick fur, which retains heat. Additionally, their layer of blubber under the skin provides insulation. While their metabolism can adjust to help regulate body temperature, the most direct response to maintaining warmth in cold environments would be related to their fur and fat.

So, the most correct response would be:

Their thick fur retains heat.
