Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.

Yes volcanoes erupt different types of magmas
Marine climate tend to has <span>warm winters and cool summers.
Regions with marine climate mostly located in a region with low elevation. Regions with low elevation tend to have higher temperature, but the existence of water near that region even out the temperature which resulted in moderate level of temperature all year long.</span>
Answer:
they may "loop out" of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions
Explanation:
At the G1 checkpoint, cells decide whether or not to proceed with division based on factors such as: Cell size
