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:

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

Correct answer · Option 2

Aestivation during peak summer and hibernation during peak winter, both taking place in deep burrows.

Frogs take shelter in deep burrows to escape extreme heat (summer sleep or aestivation) and extreme cold (winter sleep or hibernation).
