Answer:
How do tadpoles different form adult frog ?
Explanation:
When the tadpole reaches the froglet stage, it is almost a full adult. At this point, the tadpole's gills have disappeared, and its lungs have enlarged. This means it is ready to leave the water and live on land. Once its tail disappears, it will become an adult frog.
