NEET BIOLOGY

Detailed explanation-1: -All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals. Normal temperatures for mammals range from 97° F to 104° F.

Detailed explanation-2: -Warm-blooded animals are defined as animals that can regulate and maintain constant internal body temperature. They can survive in any temperature range as they can adapt to it easily. Mammals are the best examples of warm-blooded animals.

Detailed explanation-3: -Mammals are warm-blooded animals and most of the animals maintain a nearly constant body temperature and it does not change with the surrounding environment temperature. They have several internal mechanisms that help them warm up in colder areas and cool down in warmer areas.

Detailed explanation-4: -Warm-blooded body systems are also known as endotherms, since they internally regulate temperature. Cold-blooded animals, also be known as ectotherms, rely on the environment around them to regulate their body temperatures.

Detailed explanation-5: -Warm-blooded animals, such as mammals and birds, were able to maintain their body temperature regardless of the surroundings. Cold-blooded animals, such as reptiles, amphibians, insects, arachnids and fish, were not.
