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. Therefore, the correct response would be:

Their thick fur retains heat.

Additionally, polar bears have a layer of fat beneath their skin that also provides insulation against the cold. While their metabolism does play a role in heat production, the primary method of maintaining warmth in extreme cold is through their fur and fat insulation.
