Question
Pigeon, platypus and panda are ___.
- Homeothermic
- Poikilothermic
- Hyperthermic
- None of the above
Hint:
Homeotherms are the ones that can survive only when the internal body temperature is within a narrow range.
The correct answer is: Homeothermic
Homeotherms are the ones that can survive only when the internal body temperature is within a narrow range. Example mammals and birds.
Hence, homeotherms is the correct answer.
