Is the frog completely adapted to life on land

No

Explanation:

There are numerous different species of frogs around the world, coming in different sizes, colors, and behaviors. All frogs though are still amphibians, practically meaning that they are animals that live both in water and land, or rather they need both in order to survive. At first look, the frogs maybe seem as well completely adapted to terrestrial life, but that is not the case, as the frogs still need water in order to be able to survive because their skin is not made to function without water for prolonged periods of time, they still have a body and limbs that are made for swimming, and they need water for hatching their eggs, as well as for the development of newly hatched frogs, as they do not have any limbs when they are born and can only swim until they develop them.
