Maintaining acidity- <span>In case the pH in the environment drops a lot (becomes very acidic), there is a flux of H ions from the cell's cytoplasm into the cell's vacuole thereby increasing acidity to required level and thus maintaining the </span><span>specific pH </span><span>in the cells internal environment as well.
Turgidity- </span><span>Vacuoles regulate the turgidity by regulating the amount of water inside the cell. </span>
cell has excessive water:<span> vacuole absorbs the water and then diffuses it out of the cell.</span>
cell lacks water<span>: water from the vacuole gets passed back into the cell thereby maintaining turgidity.

your answer is B. because An animal must do three things to control body temperature. First, the animal must find a source of heat. Second, it must find a way to conserve heat when temperatures in the environment are too cold. Third, it must find a way to get rid of extra heat when temperatures in the environment are too hot.
We can say that the amount of time it takes a car to reach a certain velocity means that some have less air resistance than others.
