The process through which the water moves inside these cell is called osmosis.

Explanation:The one-celled organisms have some structures called contractile vacuoles which help them to remove excess of water from their body.The water enters in the body through osmomis.Osmosis is the movement or transfer of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration, by which equal concentration is achived on the both sides. Osmosis is passive transport which means it does not require any energy.There is high solute(cell organels in this case) concentration inside the cell and low solute concentration in surrounding water and hence water enters inside the cell.It is necessary to expel excess of water from the cell as if the water is not expled from the body then water will continuously enter inside the cell as a result of which the cell will burst(same as raisins burst in water when they are kept for too long).The concentration of salt water is similar to the concentration of the cell hence contractile  vacuoles has a little value in the ocean (salt water).

Result: the process of movement of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration is known as osmosis.

C: structures found in single- celled organism can act in a manner similar to tissue and organs in multi-cellular organisms

Explanation:

The question above shows a certain similarity in the function of structures of unicellular and multicellular organisms. As we can see, vacuoles are indispensable in balancing water within single-celled organisms. This function is similar to the function of the kidneys, in multicellular organisms, which is also responsible for the balance of water.

In addition, the function of the kidneys is, among others, to filter the blood to eliminate substances harmful to the body, such as ammonia, urea and uric acid. They also work to secrete substances important to our health. The kidneys receive blood from the renal arteries, branches of the aorta that come directly from the heart.

This is because their cells are usually hypertonic to the freshwater they swim in. Their cells will always have dissolved osmotically-active molecules that are critical for cell function.  Therefore, osmotically, water will move from the freshwater to the inside of the cells. If not regulated, the cells would swell and lyse. Therefore excess water has to be actively pumped out to maintain cell homeostasis.

Homeostasis is how the organism maintains constant internal conditions. If paramecia were unable to expel the water they take in from their environment they would start to expand and eventually lyse. The paramecia maintains a constant volume by pumping this water back outside of the cell. Thus, this is a homeostatic function.

The correct answer is homeostasis.

Explanation:

A self-regulating procedure taking place within an organism, which permits them to sustain a stable internal condition level is termed as homeostasis. In case, if an organism fails to sustain homeostatic balance, the eventual result would be death. Water balance, temperature, salt concentration, and pH are some of the several internal conditions, which are required to maintain comparatively stability.

Some of the single-celled pond organisms like paramecium comprise contractile vacuoles, which remove additional water out of the cell. As water balance is a part of sustaining homeostatic balance for an organism, thus one can study homeostasis by witnessing the modifications within the contractile vacuole when the species is placed in distinct solutions.

have gained water and burst.

Explanation:

Vacuoles are large vesicles originating from the endoplasmic reticulum and the Golgiense complex. They are membrane cell structures and are therefore typical of eukaryotic cells. They have selective membrane, like all cell membranes. Thus, the content inside the vacuole is different from the cytoplasmic content.

There are different types of vacuoles, but in protists it is common to have contractile type vacuoles, whose main function is to pump the excess water inside the cell out of it. This pumping of water ensures that the body maintains its ion and molecule concentrations in the desired amount and does not rupture. In addition, this vacuole is also responsible for excretion.

However, a manufacturing company has dumped its waste into a nearby lake, and this waste has the ability to paralyze the contractile vacuoles of certain protists. After an analysis, a biologist would see that the vacuoles gained excess water and burst.
