Answer:
The correct answer is A. control the movement of substances in and out of the cell.
Explanation:
All cell membranes are made up of lipids and proteins. Lipids are organized in two closely adjoining sheets that form a lipid bilayer. This bilayer provides the basic structure of the membrane and acts as a permeability barrier (impermeable) for most water-soluble molecules. Cells live and grow by exchanging molecules with the surrounding environment and the plasma membrane acts as a barrier that controls the transit of molecules into and out of the cell. As the interior of the membrane (the lipid bilayer) is hydrophobic, the membrane tends to block the passage of almost all water-soluble molecules (which dissolve in water). Protein molecules, which are normally “dissolved” in the lipid bilayer, act as mediators or facilitators of almost all membrane functions, either by transporting specific molecules through it or by catalyzing membrane-associated reactions, such as synthesis of ATP.

This question is missing the options. I've found the complete question online. It is as follows:
After receiving several tickets for speeding, Joseph lost his driver’s license for several months. When he got his driver’s license back, Joseph stopped speeding. The reason he stopped speeding is due to the consequence known as:
a) negative reinforcement
b) positive punishment
c) negative punishment
d) response chaining
Answer:
The reason he stopped speeding is due to the consequence known as:
c) negative punishment.
Explanation:
Reinforcement and punishment are means used to teach a person or animal to behave or to not behave a certain way. While reinforcements seek to motivate a certain behavior, punishments seek to discourage an undesirable behavior.
<u>We can have positive and negative punishments. Positive punishments consist of adding something that is unpleasant - for instance, the speeding tickets. On the other hand, negative punishments consist of removing something pleasant, taking away something desirable. When Joseph lost his license for several months, he lost something he needed and enjoyed. He was no longer allowed to drive. That is a negative punishment. With this punishment, he finally learned to stop speeding. </u>
