Answer:
She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)
Explanation:
This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.
The hypothetical cell will approximately contain 94 percent (94%) of water.
- If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.
- If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.
- Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.
- In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).
