Answer 1

Polar bears maintain homeostasis in freezing cold weather primarily through two key adaptations: their thick fur and their layer of fat (blubber). Among the options provided, the most accurate response would be:

**Their thick fur retains heat.**

While the metabolism can play a role in thermoregulation, the primary adaptations for cold weather involve insulation provided by thick fur and fat layers, which are essential for retaining body heat.
