Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many chromosomes does each daughter cell contain compared to the mother cell immediately after cell division?
A
the same number
B
half as many
C
twice as many
D
four times as many
Explanation: 

Detailed explanation-1: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.

Detailed explanation-2: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.

Detailed explanation-3: -Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Detailed explanation-4: -When the cell divides, the copies are pulled apart, and each new cell gets one identical copy of each chromosome. This type of cell division is called mitosis, and it produces cells with a total of 46 chromosomes.
