HUMAN NUTRITION

Detailed explanation-1: -To insulate the marine mammal, blood vessels in blubber constrict, or get smaller, in cold water. Constricted blood vessels reduce the flow of blood, thus reducing the energy required to heat the body. This conserves heat. BuoyancyFinally, blubber helps marine mammals stay buoyant, or float.

Detailed explanation-2: -Solution : In the polar seas, aquatic mammals like seals have a thick layer of fat called blubber below their skin that acts as an insulator and reduces loss of body heat.

Detailed explanation-3: -Blubber is a thick layer of fat (adipose) tissue. Animals store extra digested food in the form of adipose tissue, which contains molecules called lipids. Adipose tissue has a relatively low thermal conductivity, which means that it does not transfer heat as well as other tissues and materials-such as muscle or skin.
