Question

mitosis is necessary for our bodies to heal and grow. which of these steps describes how mitosis maintains the chromosome number of an organism?
duplicated chromosomes are split into two identical cells.
genetic information is exchanged between chromosomes during cell division.
chromosomes are independently assorted into four genetically different cells.

Explanation:

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. The key characteristic is that it produces two identical cells. The first option "Duplicated chromosomes are split into two identical cells" correctly describes this process. The second option about genetic information exchange is related to meiosis (crossing - over). The third option about four genetically different cells is also a feature of meiosis (producing gametes).

Answer:

Duplicated chromosomes are split into two identical cells.
