Answer: D. They fill new roles in the changed environment.

Explanation:

Mass extinction is the phenomena of rapidly decrease in the abundance of species from their native land. This is typically caused by catastrophic event like nuclear explosion, tsunami, earthquakes and others. This causes a drastic environmental change.

Some members which are left may play an important role in adapting the change in the environment. They fill up their ecological niches to survive and reproduce this helps in restoring the ecosystem in the changed environment.

if a human cell with a chromosome number of 46 undergoes meiosis, what number of chromosomes will be in each daughter cell?
KiRa [710]

Explanation:

It's a piece of cake. Here we are provided with the information that a human cell with a chromosome number of 46, undergoes meiosis, what number of chromosomes will be in each daughter cell.

To solve this question first you must be aware about the word meiosis. Meiosis is a type of cell division. It's end product results in the formation of four daughter cells each having half the number of chromosomes as that of the parent cell.

Did you notice? That formed daughter cell will have half the number of chromosomes as that of the parent cell. Hence, 23 chromosomes will be in each daughter cell.
