Isn't it the cell membrane? The cell membrane controls what goes in and out of the cell using active and passive transport. Osmosis being a part of passive transport.
Answer: D. economic incentives
Explanation:
Economic incentive refers to the kind of motivation strategy in which the person is provided with financial assistance and fulfill other kind of preferences according to needs, desire and wants of the person in return receiving the required task to be done or for achieving a social goal.
The given situation is an example of economic incentive this is because of the fact that mothers are provided with the paid family leave from work this is helpful in increasing the birth rate of woman. This is in effort for preventing a declining population.
Because earth has natural cycles it goes through with ecosystems, and when we get involved with trying to help one spectrum of the natural world (rabbits for example) we hurt another (wolves, by over feeding, increasing the population, then exhausting the population of rabbits over a time.)

after the geological even the farthest layer down is the oldest
ah I remember learning this... So in the cell membrane their are entrances called pumps that force ions (positively charged molecules) to move from low concentration to high concentration. During active transport, which is the process i just described, the sodium potassium pumps job is to move sodium ions ( Na+ ) ions out of the cell and move potassium ions (K+) into the cell.
1. three sodium ions are positioned in the carrier protein.
2. Atp molecule is split that create energy that bonds to the carrier.
3. the pump changes shape and opens up to the outside of the membrane, giving the potassium ions (K+) a chance to come inside. So two potassium ions fit inside and they enter the cell.
4. When the potassium goes inside, the phosphate molecule is released ( What split from the ATP molecule earlier)
