Answer:
homologous structure
analogous structure
natural selection
This is known as an analogous structure.
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.
To learn more about why your friend is in the hospital, you should research vestigial structures.
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).
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.

When you combined hydrogen and oxygen they produce water rather than hydrogen peroxide. When molecular hydrogen and oxygen are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.
At specific heights of the tree i guess, like the canopy and below.
Explanation:
there are different zones due to there being different heights
They have
- different masses
- mass numbers are different
- different amount of neutrons
