Answer :
A hy-potonic solution is one with a lower concentration of dissolved substances compared to the solution it is being compared to. This difference in concentration affects how water moves across a semi-permeable membrane, such as a cell membrane.The correct option is 4.
A solution with a higher concentration of water and a lower concentration of solutes is considered hy-potonic because it has a tendency to move water into cells due to os-motic pressure.
A) Beaker A
- Beaker contains 70% water and the cell has 80% water.
- The cell has a higher water concentration compared to the beaker, so water would tend to move into the cell.
- This suggests that Beaker A contains a hy-potonic solution.
B) Beaker B
- Beaker contains 80% water and the cell has 80% water.
- The concentrations of water are the same in both the beaker and the cell.
- This does not indicate a hy-potonic solution.
C) Beaker C
- Beaker contains 90% water and the cell has 80% water.
- The beaker has a much higher water concentration compared to the cell.
- Water would tend to move into the cell due to the concentration gradient.
- This suggests that Beaker C contains a hy-potonic solution.
It seems that **Both beakers A and C** contain hy-potonic solutions. These solutions have a lower concentration of dissolved substances than the cells they are being compared to.
