What statement best explains why this occurred?

• The cell was submerged in a pure water solution

• The cell was submerged in a solution with a higher water concentration than the inside of the cell.

• The cell was submerged in a solution with an equal water concentration to the inside of the cell.

• The cell was submerged in a solution with a lower water concentration than the inside of the cell.

Multiple Choice

Shira is analyzing samples of red blood cells using a microscope. Her observations are shown.

Shira observes that the shape of cell A appears normal, while Cell B appears swollen and Cell C is shrunken. The shrinking of Cell C indicates that the cell is reacting to what?

• lower solute concentration outside the cell than inside

• an anaerobic environment outside the cell

• higher solute concentration outside the cell than inside

• more oxygen inside the cell than what can be used
