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.
Answer:
Gap Junctions.
Explanation:
Gap junctions are intercellular channels that allows the cell transfer of molecules, ions and electric impulses.
They are connected through the protein channel and are found in many parts of vertebrate and invertebrate nervous systems.
Its most important function is to control the activities of adjacent cells.
A hypothesis becomes a scientific theory when it has been thoroughly tested, and when whoever made the hypothesis now has proof of why their hypothesis was correct/incorrect.
