PLEASE HELP QIUCK, I'M A LITTLE CONFUSED. THANKS!

What is mitosis in a living cell?

A. the separation of the genetic material of a cell into two completely identical sets, one for each of the daughter cells created during cell division

B. the creation of two daughter cells with half the number of chromosomes that the parent cell has by the process of cell division

C. the creation of a larger amount of cytoplasmic material that can then be split among the daughter cells of a parent cell

D. the separation of existing genetic material by splitting chromatids at the centromere to create two similar nuclei in another cell

Option A. the separation of the genetic material of a cell into two completely identical sets, one for each of the daughter cells created during cell division.

Explanation:

Mitosis is a type of cell division in which a single parent cell is divided into two identical daughter cells. In mitosis, the parent cell is diploid i. e. double number of chromosomes. When replication of chromosome occurs, two identical copies of chromosome are made which is distributed to each daughter cell so the daughter cells are also diploid.

This type of cell division occurs in somatic cells or body cells.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
