Which term describes animals that maintain a constant body temperature?

• A. Cold-blooded
• B. Warm-blooded
• C. Ectothermic
• D. Endothermic

Answer: (B)

Maintaining a constant body temperature is about thermoregulation through internal heat management. Warm-blooded describes animals that keep their internal temperature steady by producing and retaining heat, a trait typical of mammals and birds. This label conveys the idea of a stable body temperature in everyday biology, which is exactly what the question is asking about. In contrast, cold-blooded refers to animals whose body temperature varies with the environment, and ectothermic is the technical term for those organisms whose heat comes primarily from outside. Endothermic is the precise scientific term for animals that regulate their temperature metabolically. So, the term that best communicates the described trait in common biological language is warm-blooded.
