Question

use the information and model to answer the following question. students are studying the effects of different solutions on red blood cells. they place red blood cells in different beakers with varying concentrations of nacl. the typical red blood cell has a 0.9% nacl concentration. beaker x: 0.5% nacl solution, beaker y: 0.9% nacl solution, beaker z: 1.5% nacl solution. ... it results should student expect after placing the red blood cell in each of the solutions? drag & drop the answer: the cell will remain unchanged, water will move out of the cell causing it to shrink, water will move into the cell causing it to swell. in beaker x, in beaker y, in beaker z

Explanation:

To solve this, we analyze the osmotic effects based on NaCl concentration relative to the red blood cell's internal (0.9% NaCl) environment:

Beaker X (0.5% NaCl Solution)

• The solution is hypotonic (lower solute concentration than the cell).
• By osmosis, water moves from the solution (low solute) into the cell (high solute), causing the cell to swell.

Beaker Y (0.9% NaCl Solution)

• The solution is isotonic (same solute concentration as the cell).
• There is no net water movement, so the cell remains unchanged.

Beaker Z (1.5% NaCl Solution)

• The solution is hypertonic (higher solute concentration than the cell).
• By osmosis, water moves from the cell (low solute) into the solution (high solute), causing the cell to shrink.

Final Drag-and-Drop Answers:

• In Beaker X: water will move into the cell causing it to swell
• In Beaker Y: the cell will remain unchanged
• In Beaker Z: water will move out of the cell causing it to shrink
