Question

use the information and model to answer the following question. students are studying the effects of different tonicities 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. what results should students expect after placing the red blood cell in each of the solutions? drag & drop the answer: in beaker x, in beaker y, in beaker z, the cell will remain unchanged, water will move into the cell causing it to swell, water will move out of the cell causing it to shrink

Explanation:

Step1: Understand tonicity concepts

Osmosis occurs based on solute - concentration differences. A typical red - blood cell has 0.9% NaCl concentration.

Step2: Analyze Beaker X

Beaker X has 0.5% NaCl. It is hypotonic compared to the cell. Water moves into the cell by osmosis, causing it to swell.

Step3: Analyze Beaker Y

Beaker Y has 0.9% NaCl. It is isotonic to the cell. There is no net movement of water, and the cell remains unchanged.

Step4: Analyze Beaker Z

Beaker Z has 1.5% NaCl. It is hypertonic compared to the cell. Water moves out of the cell by osmosis, causing it to shrink.

Answer:

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
