Answer 1

Polar bears maintain homeostasis in freezing cold weather primarily through their thick fur, which retains heat. While their metabolism can adjust to help them maintain body temperature, the insulation provided by their fur and the layer of blubber underneath are key adaptations that help them survive in extremely cold environments. Therefore, the best response would be:

**Their thick fur retains heat.**
