How do polar bears maintain homeostasis in freezing cold weather? (1 point)

Question

Responses

Their metabolism slows down to preserve heat.

They hibernate in warm areas in order to heat their bodies.

Their thick fur retains heat.

Their metabolism speeds up to produce heat.

Answer 1

Polar bears maintain homeostasis in freezing cold weather primarily through their thick fur, which retains heat. While their metabolism can adjust to produce heat as needed, the most significant adaptation is their insulation from the cold. Therefore, the best response would be:

Their thick fur retains heat.
