Which of the following do tadpoles use to breathe?
That's Correct!
It's Wrong!
When a frog first hatches, it is called a tadpole. It lives in the water and breathes through temporary gills. After 4 weeks, the gills begin to disappear, and lungs begin to form.
On the other hand, a tadpole begins to develop lungs after the gills start to disappear. After 11 weeks, the lungs are completely developed. It is preparing for its life on land.
