If there are 8 centromeres in metaphase, how many centromeres will be present in anaphase? a. 4b. 8c. 16d. 32

B.8

Explanation:

In a dividing cell, each chromosome consists of two chromatids. Both the chromatids remain attached at the centromeres. If in a dividing cell there are 8 centromeres, indicates that dividing cell has 8 chromosomes. Chromosomes separate during anaphase. The cell is still dividing and not separated into two daughter cells. Therefore, if the cell has 8 centromeres during metaphase, the same number of centromeres will be present during anaphase. Thus, 8 is the correct answer.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
