KBC Offline Quiz 2021: What are mammals covered with?
c. Hair or Fur
Answer: c. Hair or Fur
One of the most important characteristics of mammals is that they are warm blooded and need a high body temperature in order to survive. This is why their bodies are covered in hair or fur.
Hair or fur form a layer on the body which helps keep the body's temperature higher than that of the environment by trapping air. The thicker the fur, the warmer the body. This is also the reason behind the fur of some animals being oily.
While keeping the body warm, hair also keeps the sun off the body and helps regulate the temperature which makes survival easier.
