Question

which statements best describe natural selection? check all that apply. populations must have genetic variation. genetic mutations do not produce advantageous traits. natural selection occurs when the environment changes. evolution works independently of natural selection. organisms best suited for the environment survive and reproduce.

Explanation:

• Genetic variation is required for natural selection, as it provides traits that can be selected for or against.
• Genetic mutations can produce advantageous traits that help organisms survive.
• Environmental changes drive natural selection by favoring traits suited to new conditions.
• Natural selection is a primary mechanism of evolution, so they are not independent.
• The core of natural selection is that well-suited organisms survive and reproduce.

Answer:

• Populations must have genetic variation.
• Natural selection occurs when the environment changes.
• Organisms best suited for the environment survive and reproduce.
