Question

which best describes the importance of mitosis to living organisms?
genetic variation and growth
growth and development
development and sexual reproduction
sexual reproduction and genetic variation

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. It is essential for growth (increasing the number of cells in an organism) and development (as cells divide and differentiate to form tissues and organs). Genetic variation mainly comes from meiosis (in sexual reproduction) not mitosis. Sexual reproduction involves processes like gamete formation (meiosis) rather than mitosis.

Answer:

growth and development
