How does a fish breathe in water?
A fish breathes by drawing water into its mouth and passing that water through the gills. In the gills, dissolved oxygen from the water is absorbed. Then water exits the fish's body through slits in the gills.
Briefly describe the amphibian life cycle.

Explain how the three groups of mammals (placental, marsupial, and Monotreme) differ in the way that they reproduce?
In placental mammals, , the female's placenta provides all the nutrients for the growing baby. They give birth to fully formed young.
Marsupial mammals give birth to poorly developed young, which find their way into a pouch for the remainder of the development.
Monotreme lay eggs, unlike any other mammals.
