13. The diagrams show steps of a cell process.

What is the name of the process shown in the diagram? (The letters are for identification but do not
indicate the order of the process.)

Answers

Answer:

It's mitosis. Notice how the daughter cells have the same number of chromosomes as the parent cell. This does not happen in meiosis where the daughter cells after the first division will have half of the starting chromosomal set

The name of the process that is shown in the diagram is known as Mitosis. This is because the daughter cell holds the exact amount of genetic content as compared to the parental cell.

What is Cell division?

Cell division may be defined as a type of biological process through which a parent cell divides into two or more daughter cells. It takes place as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.

There are two types of cell division that may normally exist. They are mitosis and meiosis. Mitosis involves the formation of two daughter cells from a parental cell that contains the same amount of genetic content.

While meiosis involves the formation of four daughter cells from a parental cell that contains half the amount of genetic content as compared to the parental cell.

Therefore, mitosis is the name of the process that is shown in the diagram.
