Answer 2

Answer:

The required answer is an option (2) Dilute solution

Explanation:

• When water moves through a semipermeable membrane in an osmotic process, it does so in accordance with the gradient of water concentration across the membrane, which is inversely proportional to the concentration of solutes. Select molecules or ions can diffuse through semipermeable membranes, also known as selectively permeable membranes or partially permeable membranes.

• Osmosis simply moves water across a membrane, whereas diffusion moves elements both inside and outside of cells. The semipermeable barrier restricts the water's ability to diffuse solutes. In red blood cells and the membranes of kidney tubules, the aquaporin proteins that promote water transport play a significant role in osmosis, which is not surprising.

• A specific instance of diffusion is osmosis. Water flows from a region of high concentration to one of low concentration like other substances do. What causes water to move at all is a question that should be evident. Imagine a beaker with two sides or halves separated by a semipermeable membrane. The water level is the same on both sides of the membrane, but variable concentrations of a dissolved substance, or solute, cannot pass through the membrane (otherwise the concentrations on each side would be balanced by the solute crossing the membrane). There will be different amounts of water, the solvent, on either side of the membrane if the volume of the solution is the same on both sides of the membrane but the solute concentrations are different. If there is more solute in one region, there must be less water there, and vice versa if there is less solute there.
