The correct answer is C. New experiments can affect previous scientific explanations.

Explanation: An experiment is a way of checking a phenomenon under specific conditions to analyze its effects or to verify a hypothesis. An example of this is the statement because before the seventies it was believed that new neurons could not be generated in an adult brain, however, after conducting an experiment on songbirds it was found that it was possible. Therefore, it confirms that new experiments can affect previous scientific explanations because new experiments can test hypotheses that modify previous explanations. So the correct answer is C. New experiments can affect previous scientific explanations.

Answer:

The answer is C, New experiments can affect previous scientific explanations. Please mark BRAINLIEST.

Explanation:

Since the scientist did the experiment before and decided that they could not make new neurons yet later tested that that was wrong and that female songbirds can produce new neurons, that fact therefore, disproved  his theory previously. It affected the theory he had before, not after, not before.
