Hibernation in ectotherm and endotherm > Both snake and weasel hibernate. Which of the following is correct? > > A. They will die when temperature decreases below the critical temperature. > > B. Weasel will die when temperature decreases below the critical temperature. > > C. Snake will die and weasel will wake up when the temperature decreases below the critical temperature. > > D. Weasel keeps low body temperature and slow heart rate during the entire period of hibernation. I don't think any of them should die, they would have some adaptation to prevent that. So,is the answer (D) ? What is the snake's adaptation in this situation ?

Weasels don't hibernate. See <

Both will die when the temperature falls below a certain level. The difference between snakes (ectotherms) and weasels (endotherms) is that the snake's body temperature will fluctuate more, depending on the surrounding temperature.
