Blood cells do not shrink in blood because blood is :

Options

A. hypotonic
B. isotonic
C. equimolar
D. hypertonic

Explanation

To solve the question "Blood cells do not shrink in blood because blood is:", we need to analyze the properties of different types of solutions in relation to blood cells. Here’s a step-by-step breakdown:

### Step 1: Understand the Types of Solutions
1. **Hypotonic Solution**: This solution has a lower concentration of solutes compared to another solution. If blood cells were placed in a hypotonic solution, they would swell and potentially burst due to water influx.
2. **Isotonic Solution**: This solution has the same concentration of solutes as the cells. In an isotonic environment, there is no net movement of water into or out of the cells, which means the cells maintain their shape and size.
3. **Equimolar Solution**: This term refers to a solution that contains the same number of moles of solute per volume of solvent. While it can be related to isotonic solutions, it is not a standard term used in this context.
4. **Hypertonic Solution**: This solution has a higher concentration of solutes than another solution. If blood cells were placed in a hypertonic solution, they would lose water and shrink.
