Cat- looks like parents when it is born, grows to full size adult cat. Frog- Goes through metamorphosis: born an egg, grows to tadpole, tail shortens and grows legs to adult frog.
Long legs to help frogs jump. Color helps them blend in to their environment. Webbed feet help them swim. Long tongue helps them catch insects to eat.
3 stages- Egg, Nymph, Adult
Mutation
Adaptation
Inherited behaviors that help animals survive.
If a mutation helps a plant or animal survive in its environment, it had a better chance to live and reproduce to pass off the gene to its offspring.
They both are hard and provide support to the body.
Internal skeletons are inside the body, exoskeletons are outside the body.
Behavioral adaptation
Tadpoles breathe through gills when they are tadpoles. When they grow to be adult frogs they use lungs to breathe.
Internal skeleton
Extinct Species
Succession
Structural adaptation
Metamorphosis
They may have less competition for resources
Spiracles
Over many generations
Useful changes in the body parts of an animal.
Giraffe can reach high into trees to eat.
Exoskeleton
Stomata
4 stages-Egg, Larva, Pupa, Adult
