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.

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.

Penn Foster
The three muscles that are usually used for intramuscular injection are deltoid muscle, vastus lateralis muscle and gluteus medius muscle. The one most often used for babies I think is the deltoid muscle. Please ask if you need more explaining or if you need anything else. I hope this helps. :D
The correct answer is - hierarchical
Each entry in a(n) hierarchical database has one parent node, with the parent node having several child nodes.
A hierarchical database model is a data model where the data is organized into a tree like structure. The data is stored as records and these are connected to one another through links.
