Proteins, carbohydrates, and lipids (including cholesterol and phospholipids) make up the majority of the plasma membrane. Intracellular components are shielded from the extracellular environment by the plasma membrane. The materials that enter and leave the cell are controlled by the plasma membrane, which mediates cellular functions. All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane. Lipids (phospholipids and cholesterol), proteins, and carbohydrates make up the majority of the plasma membrane. The extracellular environment is shielded from intracellular components by the plasma membrane. By controlling the substances that enter and leave the cell, the plasma membrane facilitates biological processes. All cells contain a membrane that divides the interior from the external environment. This membrane is known as the cell membrane or the plasma membrane. A lipid bilayer that is semipermeable makes up the cell membrane. The cell membrane controls the movement of materials into and out of the cell.

What are the careers you have learned though? I would love to help but there’s not enough information :)
the answer for the first one is B
and the second is B
Nitrifying<span> bacteria in the soil convert ammonia into </span>nitrite<span> (NO</span>2-) and then into nitrate<span> (NO</span>3-<span>). This process is called nitrification. </span>
