Question

what goes in must come out quick check a cell is dropped into a saltwater solution and shrivels up. you infer that, compared to the cell, the type of saltwater solution is (1 point)
○ hypotonic.
○ isotonic.
○ tonic.
○ hypertonic.

Explanation:

To solve this, we recall the concepts of tonicity in solutions:

• A hypotonic solution has a lower solute concentration than the cell, so water enters the cell (cell swells).
• An isotonic solution has the same solute concentration as the cell, so no net water movement (cell remains same).
• A hypertonic solution has a higher solute concentration than the cell, so water leaves the cell (cell shrivels).
• "Tonic" is a general term, not specific for this scenario.

Since the cell shrivels, water is leaving it, meaning the saltwater solution has a higher solute concentration than the cell, so it's hypertonic.

Answer:

D. hypertonic
