Question

What adaptation does a young baby frog have for breathing air?

Answer 1

Tadpoles have tiny external gill flaps that extract oxygen from water as it passes over them .Tadpole open their mouths as they swim and take in water. As the mouth closes ,muscles transfer the water to the gills. These gills consist of thin membrane called LAMELLAE, which take oxygen from the water where it enters the blood stream through the process of diffusion .Tadpoles can also rise to the surface ang gulp oxygen from the air.As tadpoles mature ,the gills are absorbed by the body as other respiratory systems developed
