Explain how the thick fur of a polar bear is an adaptation to its environment.

The thick fur of a polar bear provides insulation against the cold temperatures of its Arctic habitat. This adaptation helps the bear maintain its body heat, allowing it to survive and thrive in extreme conditions where temperatures can drop significantly.

This answer is strong because it directly links the structural adaptation (thick fur) to the environmental condition (cold temperatures), demonstrating an understanding of how adaptations support survival. The question tests the ability to apply knowledge of adaptations to a specific example.
