BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The second group, the homoiotherms, maintain a constant body temperature regardless of the ambient temperature; these warm-blooded animals include birds and mammals.

Detailed explanation-2: -Birds and mammals are two classes of vertebrates that are said to be warm blooded. They possess various mechanisms to ensure that their body temperature is fairly constant, (unaffected by, and usually warmer than, their surroundings), so that they can function more efficiently and reliably.

Detailed explanation-3: -Normal temperatures for mammals range from 97° F to 104° F. Most birds have a normal temperature between 106° F and 109° F. Larger animals, such as these prairie dogs, do not use as much energy to produce the heat required to keep their larger bodies warm.

Detailed explanation-4: -Warm-blooded animals, which are mostly birds and mammals, need to maintain a relatively constant body temperature or they would suffer dire consequences. It doesn’t matter what the outside temperature is-they must maintain the same internal temperature.
