Mutation
- B.
Succession
- C.
Natural selection
- D.
Genetic engineering
- 5.An area where a population of wolves lives is getting colder. Even though the wolves do not have predators, they often die as a result of the cold temperatures. In this climate, natural selection should favor individuals that possess which of the following?

- 6.Cleaner fish feed off of the algae, fungi, and other microorganisms that are found on the teeth of larger fish. Another species of fish, called mimics, look like cleaner fish.

- A.
Eating patterns of the larger fish would change or it would die.
- B.
Eating patterns of the cleaner fish would change or it would die.
- C.
