An animal cell has four chromosomes in its nucleus. When the cell goes through mitosis, how many chromosomes will each daughter cell have? a. 0 b. 4 c. 8 d. 16

When an animal cell with four chromosomes undergoes mitosis, it duplicates its chromosomes before dividing. This duplication results in two identical sets of four chromosomes. Therefore, each daughter cell will end up with 4 chromosomes, which means the correct answer is b. 4. In essence, mitosis ensures that each daughter cell obtains the same chromosome number as the original cell, maintaining genetic consistency across cell generation. This process is vital for growth, development, and tissue repair in multicellular organisms!
