Answer the following question given this paragraph: Amphibians are vertebrates that live part of the time in fresh water and part of the time on land. They were the first vertebrates to evolve four legs and colonize the land. They most likely evolved from lobe-finned fish. Modern amphibians include frogs, toads, salamanders, newts, and caecilians. They are ectotherms, so they have little control over their body temperature. This allows them to be active in warm weather, but they become sluggish when the temperature cools. Q: Frogs are amphibians that live part of the time in fresh water and rest of the time where? Choices: - underground - in stagnant water - in salt water - on land A:
on land
