Hi, everyone. Let's take a look at the next problem. When a drop of blood is placed in a hypertonic solution, the water inside the red blood cells will a the water inside the rbcs will not be affected. B hypertonic blood will cause more water to move into the RB CS C. The water will follow the increased tonicity of the blood and move out of the RB CS or D none of the above. So let's think about our solution here. We have these red blood cells and they're in a hypertonic solution. We recall that hyper prefix means more like hyperactive a child having too much energy. So the hypertonic solution has a higher solute concentration. So we know that water will move to dilute a higher concentration. That means water is going to move from inside the cells out to the solution, trying to dilute that outer solution and bring it to an equal concentration of what's inside the cells. So our answer choice then will be choice. C the water will follow the increased tenacity of the blood and move out of the rbcs. So when we look at our other answer choices, none of the above, we can cross out since we do have a correct answer, choice A will not be affected. That's not correct. Since there is a concentration difference and a semi permeable membrane between those differences, the water will move to the area of higher concentration. And then of course choice, B hypertonic blood will cause more water to move into the RB CS is the opposite of the situation, more water would move into the RB CS if it were a hypotonic solution. So again, our answer of if a drop of blood placed in a hypertonic solution, water inside the red blood cells will choice C the water will follow the increased tonicity of the blood and move out of the RB CS. See you in the next video.
