Answer:
The correct answer is option B.
Explanation:
Homeostasis is the process or mechanism of trying to maintain equilibrium while interaction with the outside world. An example of maintaining homeostasis in the system level would be the endocytosis and exocytosis of a substance.
Endocytosis and exocytosis are the mechanisms in which molecules are brought into the cell and out of the cell depending on their need to the cell.
Thus, the correct answer is option B.
A hypertonic solution has greater solute concentration than the cytosol inside the cell. In such a case, water flows out of the cell by osmosis. This results in a decrease in turgor pressure.

Answer:
Like other cells, prokaryotic cells have a plasma membrane (see Figure below). It controls what enters and leaves the cell. It is also the site of many metabolic reactions. For example, cellular respiration and photosynthesis take place in the plasma membrane.
Most prokaryotes also have a cell wall. It lies just outside the plasma membrane. It gives strength and rigidity to the cell. Bacteria and Archaea differ in the makeup of their cell wall. The cell wall of Bacteria contains peptidoglycan, composed of sugars and amino acids. The cell wall of most Archaea lacks peptidoglycan.
