When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?

The new solution has a higher concentration than the isotonic saline solution

Explanation:

Here, we want to deduce what has happened in the question.

We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.

Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.

What has occurred is the process of Osmosis

Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.

So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
