Frog Research

Unlike humans, frogs need to respond to the environment to maintain their body temperature. When it is warm they move into the sun. When it is too cold they burrow into the mud and hibernate. Maintaining these stable internal conditions is described as...

• homeostasis

• reproduction

• transcription

• respiration

Most frogs are native to freshwater habitats. They cannot survive if their environment has a salt concentration higher than 10%. If placed in a tank with 20% salt concentration what would happen to the frog cells?

• The frog cells would shrink as water moved out towards the salt

• The frog cells would swell as water moved out towards the salt

• The frog cells would swell as water moved into the cell away from the salt

• The water would move in and out of the cells, so there would be no change
