When a person is dehydrated, water moves out of cells by:Question 3Select one:a.osmosisb.primary active transportc.secondary active transportd.perfusione.diffusion
Solution
The correct answer is a. osmosis.
Here's a step-by-step explanation:
-
Dehydration means that the body doesn't have as much water as it needs. This can happen when you lose more fluids than you take in.
-
In the human body, water can move across cell membranes because of a process called osmosis.
-
Osmosis is the movement of water from an area of low solute concentration to an area of high solute concentration.
-
When a person is dehydrated, the concentration of solutes in the blood outside the cells is higher than inside the cells.
-
As a result, water moves out of the cells into the blood to try and balance the concentration of solutes. This is osmosis.
-
Therefore, when a person is dehydrated, water moves out of cells by osmosis.
