106.What are the characteristics of mammals
Blood vessels in the skin contracts to decrease the amount of blood that flows through them. This allows heat to stay inside the body. Sweat glands in the skin reduce perspiration to none . Hairs on the skin stands up because the Arrector pili muscle has contracted which produces goose bumps on the skin reducing skin surface are
