Biology · STRUCTURAL ORGANISATION IN ANIMALS

During unfavorable thermal extremes, frogs avoid harsh environmental conditions by entering dormant phases. Identify the correct physiological pairing of these dormant states:

1. A
   Hibernation during peak summer and aestivation during peak winter, both occurring inside water.
2. B
   Aestivation during peak summer and hibernation during peak winter, both taking place in deep burrows.
3. C
   Camouflage during winter and mimicry during summer, both mediated entirely by hepatic glycogen.
4. D
   Continuous cutaneous respiration coupled with pulmonary ventilation exclusively during winter sleep.
