Answer #1

The statement is completely FALSE that the vertebrate animals cannot regulate their internal environment through homeostasis they have evolved hair to stay warm.

The vertebrates are of two types those who can regulate theiir body temperature; ECTOTHERMS and those who cannot control their body temperature; ENDOTHERMS.

It is true that the hairs are evolved only to keep the body warm in copd weather. They stand erect when it is cold (PILOERECTION)..

Only the endothermic vertebrates cannot regulate their internal body temperature through homoeostsis and they do not have body hairs that could keep them warm.
