How are amphibians and reptiles alike and different?

However, reptile eggs tend to have a harder shell while amphibians have soft, permeable eggs, more like fish eggs. A big difference in their development is that amphibians have an aquatic larval form after hatching.

How are frog organs and organ systems different and similar from human organs and organ systems?
