Purely genetics... Not only the hair is long, it is thicker and in realy cold klimats are holow with air traped inside.
Most aquatic animals living in cold climates can survive quite nicely thanks to their adaptations. Some animals have hair and others like whales have a tremendous amount of blubber that helps to insulate them from cold temperatures.
When the temperature is cold, the hair and fur on animals fluffs up, creating air pockets between hairs that insulate the body from the cold.
They survive in different habitats. Animals with hair can survive in cold and warm places, and animals without hair survive in warm places.
keeps the cold out during sub zero winter temperatures. the wool can be sheared and woven into clothing
Dogs, like many animals, have hair to keep them warm in the cold weather, and to keep from getting sunburned when it is hot. The hair insulates and protects their skin.
Keratin is the structural protein for hair and nails (also horns in animals).
Animals do have hair inside their nostrils, which helps filter out dust, dirt, and other particles from entering their respiratory system. However, animals don't have as much nose hair as humans do because their sense of smell is not as dependent on detecting odors in the air.
The acid commonly found in cold wave solutions is thioglycolic acid. It is used to break the disulfide bonds in the hair, allowing for restructuring of the hair's natural shape during the perming process.
I found out that when your born you're hair is your natural color or you don't have hair. After you start growing you hair gets older as you body starts growing and getting older. As you see many seniors have white hair unless the dye or color it. In the cold a childs hair can get white because of the cold.
So they don't freeze to death. c:To insulate themselves from chilling cold
the cold air is making the water in your hair cold which makes your hair cold. if your hair is dry then there is no water in i for the hair to be as cold as it is when its wet.
