Answer:

The correct option is A. The cell is sitting in a hypertonic solution.

Explanation:

A hypertonic solution is a solution in which there are more number of solutes present in the solution than inside the cell. The solutes then tend to pass into the cell through diffusion from the solution.

As it can be seen in the diagram, the concentration of salt is more in the solution i.e 40%. Hence, the salt from the solution enters into the cell by diffusion and has a concentration of 10% inside the cell which shows the cell to be placed in a hypertonic environment.

to correctly measure the amount of water diffusion occurring when water moved over a selectively permeable membrane, you needed

larisa [96]

There are specific methods to be used when measuring the rate of diffusion over a membrane.

In order to accurately measure the rate of diffusion for water through this permeable membrane you need to account for:

The difference in pressure
The surface area of the membrane
The diffusion barrier

It would be correct to state that the speed at which any movement of water occurs is dependent on the pressure being exerted onto the water. This means that when attempting to calculate the rate of diffusion we need to account for the pressure difference. This pressure will be caused by the osmotic gradient.

You will also need to account for the surface area of the membrane and the diffusion barrier. The surface area of the membrane allows us to understand how much space the water has to be able to move from one side to the other. Meanwhile, the diffusion barrier tells us how much resistance the water will have to overcome when diffusing.

By taking all of these parameters into account, we can then use Fick's law to accurately calculate the rate of diffusion for the water and therefore the amount of water that is diffusing through the membrane.
