AP 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: -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: -Birds are warm-blooded vertebrates. They have three characteristics that distinguish them from other animals: feathers; hard-shelled eggs; and hollow bones. Like mammals, birds are warm-blooded, meaning that their body temperature stays the same no matter how hot or cold it is outside.

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: -It’s one of the most basic biology facts we’re taught in school growing up: Birds and mammals are warm-blooded, while reptiles, amphibians and fish are cold-blooded.
