Answer:
The correct option is A) ATP
Explanation:
Some ions or molecules tend to move in the cell along a concentration gradient. Such types of movement is known as passive transport. In passive transport, molecules move from a higher concentration to a lower concentration. Such kind of movement doesn't require energy.
Other kinds of molecules or ions move against the concentration gradient i.e from a lower concentration to a higher concentration. Energy is required for these process to occur.The energy used is in the form of ATP.
A mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage. Regions of the genome (called genes) provide instructions for creation of protein molecules, which perform most of the important jobs in cells. Certain types of mutations are silent and have no effect, but others affect protein production in a variety of ways.
