Question : During hibernation state, the frog respires through which of the following?
Option 1: Only heart
Option 2: Only lungs
Option 3: Only skin
Option 4: Both lungs and skin
Correct Answer: Only skin
Solution : The correct option is Only skin
Frogs and other amphibians exchange gases through their skins during hibernation, including carbon dioxide and oxygen . Because of their porous skin, which enables them to collect and release gases directly from their surroundings, they can maintain minimum respiration even when their metabolic activity is substantially reduced. Amphibians, including toads, can live because of this adaptation, which causes their other physiological processes to slow down during hibernation.
