Question
Which feature of the polar bear is cited on the slides as a structural adaptation for Arctic survival?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Polar bears have thick fur and a thick layer of subcutaneous fat (blubber) as structural adaptations for Arctic survival. These features provide insulation against extreme cold, reduce heat loss, and store energy reserves.
Hint
This combination of external and internal insulation helps retain body heat in freezing conditions.
