In multicellular organisms, life begins as a single cell until ___________ occurs, causing growth.

Arturiano [62]

The right option is; D) mitosis

In multicellular organisms, life begins as a single cell until mitosis occurs, causing growth.

Mitosis is a process of cell division, and a part of the cell cycle in which a single cell divides, and produces two identical daughter cells (new nuclei) that contains the same shares of the parent’s cell part. Mitosis occurs in multi cellular organisms, and its primary purpose is for growth, and to replace worn out cells. Mitosis contains four basic stages which are; prophase, metaphase, anaphase, and telophase.
