Which of the following is not true about polar bears? a. they all hibernate. b. they have black skin that them absorb heat. c. their fur is transparent and hollow and trap heat. d. they have oversized paws with rough pads that them walk on snow and ice.

The answer is A

They don't actually need to hibernate

Correct A). They all hibernate

The polar bear does not hibernate. Brown and black bears hibernate during the winter season in order to conserve energy and stay warm. But the polar bears do not do that except the females that are pregnant. Actually, the polar bear does need to hibernate because they are able to live on the fat that is stored in their body.

Hence, the correct answer would be option A.
