Answer: This brightly colored trait in this scenario is an example of natural selection
Explanation:
The aim of natural selection is to ensure the traits that make species better fitted to environmental pressures remain while other are eliminated.
Thus, the brightly colored trait in this scenario is an example of natural selection because:
- it appears in all population of the flower-producing plants making it well adapted to the environment.
- its emitting of no odor or rotting odor is simply a chemical defence mechanism in order to avoid from eaten by animals.
Answer:
The answer might be D
Explanation:
The answer could be D because birds with larger beaks should be capable of eating soft shell seeds, as well as hard shell seeds. So natural selection would not occur because the finches with large beaks would not die as a result of not eating soft shell seeds. The finches with large beaks should be able to reproduce offspring with the same trait. And so should the finches with small beaks.
