Question

how does mitosis contribute to the survival of an organism? by producing cells that can fuse with other cells.. by allowing cells to divide without copying dna. by creating cells with new genetic traits. by maintaining chromosome number across cell generations.

Explanation:

Mitosis is a process of cell division where a parent cell divides into two identical daughter - cells. It replicates DNA and distributes it evenly, maintaining the chromosome number in somatic cells. This is crucial for growth, repair, and asexual reproduction in organisms. Cells produced by mitosis do not fuse with other cells (that's meiosis - related for gametes), DNA is copied during mitosis, and it doesn't create new genetic traits (mutation or meiosis with recombination do that).

Answer:

By maintaining chromosome number across cell generations.
