Giraffes and mice have the same number of vertebrae despite size and function this is an example of a blank

1. homologous structure

2. analogous structure

3. natural selection

4. This is known as an analogous structure.

5. To make this determination, you need to think about if the features are the same in function or also in structure. Features that have a closely related structure and function are likely to be related.

6. To learn more about why your friend is in the hospital, you should research vestigial structures.

7. These two beetles aren't closely related, but they look and behave similarly. This is because they live in the same environmental conditions and likely share a common ancestor that lived in Gondwana (the supercontinent that included the southern continents before they split apart through plate tectonics).

8. Australia has so many genetically distinct organisms because it has been separated from other bodies of land by water for a very long time. This has created an opportunity for long-term independence of other geographic areas.

1. a host loses nutrients to a parasite

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
