Question

A)Based on Slides 9-10, how do special blood vessels in frog skin facilitate their unique respiratory process, and what might happen if their skin dries out?(1 point)
Responses

The blood vessels in frog skin allow them to yawn more effectively; if their skin dries out, they would yawn less.
