When the glucose solution described in part a is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises. based on this information, what can be said about these two solutions? a. the unknown solution had the lower concentration. b. the unknown solution had the higher concentration. c. the two solutions have the same concentration.

This question in incomplete, because I don't have any information about the glucose solution described in part A. But I can guess that the question deals with osmosis process.

The answer is: B. the unkown solution had the higher concetration.

Explanation:

The osmosis process is a movement of a solvent through a semipermeable membrane. If both solutions have the same concetration in both sides of the semipermeable membrane, there is no movement at all, because the solute concentrations are equal. But if one side of the membrane has a higher solute concentration than the other, the solvent moves through the semipermeable membrane to get to equalize the concentrations on both sides. This movement give rises to the osmotic pressure that only depends on the molar concentration of the solute.

In this case, if the unknown solution level rises, it means that there is a solvent movement towards it so, this solution concentration is higher than the other one.
