c) they have fur that appears white to blend into the environment
The adaptation of having fur that appears white helps polar bears to survive in their cold and snowy habitat. The white fur allows them to blend in with their surroundings, making it easier for them to hunt for prey and avoid predators. This camouflage is crucial for their survival as it helps them remain undetected while they approach their prey, mainly seals, on the ice. Additionally, the thick layer of fur also provides insulation, keeping polar bears warm in the freezing temperatures of the Arctic region.
I hope this helped!
