Answer:

The correct answer is osmosis.

Explanation:

Osmosis is the process in which solvent is transported down the concentration gradient across the cell membrane. Osmosis is the passive transport which do not require any use of energy to transport the molecules across the cell membrane.

Water molecule is transported by facilitated diffusion in which specialized water channels are used to facilitate the transport of water across the cell membrane through osmosis.

These specialized channels are called aquaporins which are present in both plant and animal cell membrane to pass water across the membrane.

So, water crosses the plasma membrane primarily by means of osmosis.

Which term describes the difference in the concentrations of a substance across a cell's membrane?
SpyIntel [72]

Correct answer: C) Concentration gradient

The process of movement of a particle in a solution from the region of higher concentration to the region of lower concentration across a membrane is called as concentration gradient.

For example: If we drop a few drop of dye in a glass of water, it will diffuse along a concentration gradient, i.e, the region where dye is found in highest concentration to the region where it is in lower concentration.

It will occur until the concentration of dye become uniform in all the direction in the glass of water.

Artist 52 [7]

Answer:

Inhibitors of cyclin-dependent kinases might play a role in regulating the concentration of cyclin in the cell cycle.

Explanation:

The presence of inhibitors of cyclin-dependent kinases has a great importance because it controls the concentration of cyclin that is necessary for the cell cycle. If inhibitors of cyclin-dependent kinases is absent , the amount of cyclin increases in the cell formation and cause  a great damage to the cell cycle and the cell which is produced is abnormal or other irregularities.
