Question

What adaptations permit the frog to live on land and in water?

Answer 1

Water has dissolved oxygen which is utilised by the frog in cutaneous respiration. They have lungs to breathe air, like us but when in water they can absorb all the oxygen they need through their skins. Some frogs spend the whole winter hibernating at the bottom of ponds without breathing at all.

Answer 2

$\huge\mathbb\pink{Answer}$

The frog has strong hindlegs for jumping and swimming, its skin allows it to breathe through underwater (it also has lungs to breathe with on land), and it has webbed toes on its hind feet to use for swimming.
