Question

Which description identifies a factor that influences the flow of water through the plasma membrane of a human cell?
A. The size of the phospholipids and proteins composing the plasma membrane
B.the concentration of solutes on either side of the plasma membrane
C.the presence or absence of a cell wall outside the plasma membrane
D.the number of contractile vacuoles on the surface of the plasma membrane

Answer 1

Answer:

A

Explanation:

Answer 2

Osmosis refers to the movement of water molecules across a selectively permeable membrane. During this process, water molecules move from an area of high concentration to an area of lower concentration.

• A factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).

• Osmosis is a type of passive transport mechanism that does not require energy to occur.

• During osmosis, water diffuses through a selectively permeable membrane from an area of high water concentration to an area of lower water concentration.

• In an isotonic cell, the concentration of solutes and water molecules is equal on both sides of the plasma membrane.

In conclusion, a factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).
