Which of the following features help polar bears adapt in extreme cold conditions?

Polar bears have several adaptations for extreme cold polar regions. Their white fur provides camouflage against snow and ice, helping them hunt. Long curved sharp claws help them grip slippery ice and catch prey like seals. A thick layer of fat (blubber) under the skin provides insulation against freezing temperatures. Polar bears also have a strong sense of smell to detect prey from far distances. Flat feet are not their adaptation; rather they have large paws that act like snowshoes.
