Their thick skin insulates the internal organs against the cold.

Answer 1

Polar bears maintain homeostasis in freezing cold weather primarily through the response: Their thick fur retains heat.

They also have a layer of fat beneath their skin, known as blubber, which provides insulation and helps to retain body heat. Additionally, their metabolism does not slow down significantly; instead, it is efficient enough to help them generate and conserve heat in cold environments. Thus, the thick fur and blubber are key adaptations for maintaining warmth in extreme cold.
