Mrrafil [7]

Answer:

When the cell has 0% sucrose I expect the cell to stay the same.

Explanation:

First of all, this question should not be confused for the statement "When the "cell" has 0% sucrose, did you expect the cell to have gained water, lost water, or stay the same. In this case, the correct answer would have been; gained water.

But, in this question, we are asked what happens to the cells at 0% sucrose concentration. At 0% (no solute) concentration, there is no net movement of water or solute into or out of the cell, because the cell is isotonic to the external environment (distilled water). Osmosis, a special kind of diffusion, is the movement of water, from areas of lower solute concentration to area of higher solute concentration, or from areas of higher water concentration to areas of lower water concentration through a semi-permeable membrane. If the water moves into the cells (hypertonic cells), then the cell gains water and increases in size, but if the cell loses water (hypotonic cell), then it reduces in size

The INDEPENDENT VARIABLE:
klemol [59]

Answer:

B. Is what the scientists manipulate in the experiment.

Explanation:

The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.
