Explanation:

Question 46: What is the percentage of solute in the cell?

Step1: Recall that the total percentage of water and solute in a cell (or solution) is 100%.

Step2: The cell has 90% water, so the solute percentage is \( 100\% - 90\% = 10\% \).

To determine the tonicity, compare solute concentrations. The cell has 10% solute, the solution has 5% solute. A hypotonic solution has a lower solute concentration than the cell. Since 5% (solution) < 10% (cell), the solution is hypotonic.

In a hypotonic solution (solution has less solute, more water), water moves into the cell (osmosis, water moves to higher solute concentration inside cell). This causes the cell to swell as water enters.

Answer:

10%
