- A Hibernation occurs during the summer months; aestivation occurs during the winter months in routine practice
- B Hibernation is a winter dormancy to escape cold; aestivation is a summer dormancy to escape heat and desiccation
- C Both terms describe the exact same dormancy phenomenon, just observed in different organisms overall in most cases
- D Hibernation applies mainly to insects, while aestivation applies mainly to mammals under typical conditions
Correct answer: B. Hibernation is a winter dormancy to escape cold; aestivation is a summer dormancy to escape heat and desiccation
Explanation: Hibernation is dormancy adopted during winter to escape cold conditions (e.g., bears), while aestivation is dormancy adopted during summer to escape heat and desiccation (e.g., snails, certain fish).
Concept context
