| What is cartilage? | It is a material that is softer than bone. |
| What are the backbones of sharks and rays made of? | The backbones are made of cartilage. |
| How do fins and a long, narrow body help a fish swim? | Fins keep the fish upright and help it steer, and a long, narrow body makes it easy to move through water. |
| How does the way a bird breathes differ from the way a fish breathes? | One animal uses lungs to breathe, while the other uses gills to get oxygen from water. |
| How does an amphibian change as it grows? | The animal hatches from eggs in the water with tails and breathes with gills. Then they develop legs and lungs and lose their gills. As Adults they live on land. |
| How does the skin of frogs and toads differ? | Frogs have wet, smooth skin, and toads have rough, dry, bumpy skin. |
| An animal lives in water, has fur, and breathes with lungs. Would you classify it as a mammal, a bird, a fish, or an amphibian? Why? | Fish live in water, but fish have scales, not fur. Amphibians and birds can live in water, but neither has fur. i would classify the animal as a mammal. Mammals have fur or hair, breathe with lungs, and can live in water. |
