Answer:
The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate.

The answer is <span>B. It can reproduce quickly.
A single-celled organism, as its name explains, consists of only one cell. This cell must be small because, in a large cell, it would be needed a great time for information, nutrients and other molecules to travel from one part of the cell to another (choice A. is eliminated). That small cells are able to reproduce quickly because their dimension allows them to divide to new cells quickly (even 20 minutes). Still, although it is only one cell it must maintain its structure (choice C is eliminated), and cannot tolerate all environmental conditions (choice D is eliminated).</span>
Answer:
The two factors are:
• The kind/type of surface involved.
• The force that the surface are being pushed together.
Explanation:
Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.
When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.
The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
