Answer:
The reason why the ball rolling across carpet will come to a stop faster than the one rolling across concrete is the friction (option B).
Explanation:
The contact surface on which the balls move is different. Irregularities in the carpet cause the ball in it to stop faster. The concrete surface is less irregular, and allows the ball to move a little more and then stop. This is due to friction.
In physics,<u> friction is a force that is capable of opposing movement</u>, since the contact of two surfaces limits its movement. A smooth surface produces less friction than a rough or irregular surface.
Since the friction that stops both balls occurs when they are in motion, it is called dynamic friction, that is, the force that causes a moving body to stop.

This will create cells that are not fully capable of the job they are meant to do
Answer:
The bacterial fission occurs by the following method:
The DNA replicates. The replicated DNA is copied and it moves to the opposite sides of the cell. The length of the parent cell increases. The cell divides from the center with distribution of equal amount of DNA. After this, the cell wall is formed.
In protist fission: In protist fission, the nucleus of the parent cell divides many times. After this cytoplasm separates and forms around the daughter nuclei.
