Answer:
The correct answer is A.
Explanation:
Diffusion is the net movement of a substance from a region of higher concentration to a region of lower concentration. The difference in concentration between two environments creates a concentration gradient which is what drives diffusion. Therefore, this movement does not require aid such as extra energy molecules for active transport or integral membrane proteins for directed movement, hence the answer is not B nor C. If the cell is in equilibrium with its environment, it means that the concentration of substances inside the cell is equal to the concentration outside the cell, and any movement that takes place will be random movement of substances across the plasma memberane. Movement in the cell will not cease as the cell is still active. Therefore, the answer cannot be D either.

The Earth will perform 366.25 rotations per revolution about the Sun.
<h3>What is Revolution?</h3>
This is defined as the motion around the Sun along its orbit which is common with planets such as the Earth.
The Earth rotates 366.25 times around the Sun and which is equivalent to a calendar year which is used for time keeping.

Answer:
Cellular respiration is the process by which glucose is transformed into ATP. -- It uses oxygen and gives off carbon dioxide and takes place in the mitochondria of the cells. -- It helps maintain homeostasis by transforming energy that can be used to do cellularwork.
