Flagellum is primarily a motility organelle that enables
movement and chemotaxis. Bacteria can have one
flagellum or several, and they can be either polar (one or
several flagella at one spot) or peritrichous (several
flagella all over the bacterium).
The end result of mitosis is a cell that is exactly the same as the original cell. So, if you have Cell A and cell A goes through mitosis and produces cell B... Cell B is an exact clone/replica of cell A with NO VARIATIONS. It's literally like cloning (Asexual reproduction).
Cytokinesis is part of the cell cycle, it is the last stage where a plate forms between both the cells to separate them from each other and to form two individual cells.
Mitosis is important because it is a fast way of producing replicas of cells. Cytokinesis is important to differentiate or create boundaries between the cells.
This answer is C. Disruptive selection
This is because the normal distribution curve is shifting in one direction or another
