Their thick fur retains heat.

Answer 1

Polar bears maintain homeostasis in freezing cold weather primarily through their thick fur, which retains heat. Additionally, they have a layer of blubber under their skin that provides insulation and helps to keep their internal body temperature warm. Both adaptations are crucial for surviving in extremely cold environments.
