So here we have an example problem that's asking what is the tenacity of the outside solution in comparison to the inside of the cell, and we've got these 4 potential answer options down below. Now for sure we know we can eliminate answer option d since "electrotonic" is not one of the terms that we introduced in our previous lesson video, and so this is simply not going to be correct. However, hypotonic, isotonic, and hypertonic are all terms that we did discuss in our previous lesson video.
And so when we take a look at this image right here, notice that we've got this beaker of water, and what we have in the middle is a cell, a red blood cell. Notice that this image shows that the outside of the cell has a 10% solute concentration whereas the inside of the red blood cell has a 0.1% solute concentration.
Thus, we need to denote that this 10%soluteconcentrationontheoutsideofthecell is going to be a higher solute concentration. And of course, the inside of the cell is going to have a lower solute concentration. This problem is specifically asking us about the outside solution. So, we're going to focus in on the outside solution, and we want the term that corresponds with higher solute concentration.
You might recall that the term that corresponds with higher solute concentration is going to be hypertonic. Thus, hypertonic is going to correspond with answer option c. And so we can go ahead and indicate that c here is the correct answer for this example problem.
Now of course, the inside of the cell, which has a lower solute concentration, low rhymes with hypo, so this is going to be a hypotonic solution on the inside of the cell. The inside is hypotonic and the outside is hypertonic. This concludes this example, so I'll see you all in our next video.
