Answer:
<em>The number of chromosomes is maintained through the process of mitosis during asexual reproduction. </em>
Mitosis can be described as a process in which a cell divides and produces two daughter cells which are exactly similar to the parent cell. The chromosome number of the daughter cells will be the same as the parent cells. No crossing over or recombination occurs during this type of cell division. Hence, mitosis is an effective way to maintain the chromosome number of organisms which reproduce asexually.
The question is incomplete. However, if we consider this cell as human cell - the cell contain 23 pairs of chromosomes.
Answer:
Chromosomes consists of the constricted DNA associated with the proteins. Different species has different chromosome number. Two main types of chromosomes are heterochromatin and euchromatin.
The human cells contain the 23 pairs of chromosomes or 46 chromosome. If the cell divides by the process of mitosis than the chromosome number will be same in parent as well as the daughter cell. The daughter cell 23 pairs of chromosomes. If the cell divides by the process of mitosis the cell has 23 chromosome number as the meiosis reduces the chromosome number upto half.
In science, the mantle is a layer of the earth between the core (inner layer) and the crust (outer layer).
