Question

How do polar bears maintain homeostasis in freezing cold weather?

A. Their metabolism slows down to preserve heat.
B. Their thick fur retains heat
C. Their metabolism speeds up to produce heat.
D. Their thick skin insulates the internal organs against the cold.

Answer 1

Polar bears maintain homeostasis in freezing cold weather through thick fur, fat insulation, and an increased metabolic rate.

Step-by-step explanation:

Polar bears maintain homeostasis in freezing cold weather through a combination of factors. Their thick fur retains heat by creating an insulating layer of air between their skin and internal organs. They also have a dense layer of fat under their skin, which acts as insulation. Additionally, when the temperature drops, their metabolism speeds up to produce heat.
