Question

study the diagrams below. note the concentrations of the various solutions. the membrane is permeable to both water and glucose. water water glucose glucose a. type here b. type here c. isotonic solution 1. draw arrows indicating the net movement of each material. you can draw an arrow in google slides by going to insert >>> line >>> arrow. label each arrow by dragging and dropping the provided \glucose\ or \water\ text boxes 2. is the solution in the beaker isotonic, hypertonic or hypotonic to the solution in the bag? label each

Explanation:

Step1: Analyze Solution A

The bag has 80% water - 20% glucose and the beaker has 80% water - 20% glucose. Since the concentrations of water and glucose are the same inside and outside the bag, there is no net movement of water or glucose.

Step2: Analyze Solution B

The bag has 80% water - 20% glucose and the beaker has 100% water. Water will move from an area of high water concentration (beaker) to an area of low water concentration (bag). Glucose will move from an area of high glucose concentration (bag) to an area of low glucose concentration (beaker).

Step3: Analyze Solution C

The bag has 90% water - 10% glucose and the beaker has 90% water - 10% glucose. Since the concentrations of water and glucose are the same inside and outside the bag, there is no net movement of water or glucose.

For part 2:

Step1: Solution A

The solution in the beaker is isotonic to the solution in the bag as the solute - solvent concentrations are equal.

Step2: Solution B

The solution in the beaker is hypotonic to the solution in the bag because the beaker has a lower solute (glucose) concentration and a higher water concentration.

Step3: Solution C

The solution in the beaker is isotonic to the solution in the bag as the solute - solvent concentrations are equal.

Answer:

1.

• Solution A: No net movement arrows for water and glucose.
• Solution B: Arrow for water pointing into the bag and arrow for glucose pointing out of the bag.
• Solution C: No net movement arrows for water and glucose.

2.

• Solution A: Isotonic
• Solution B: Hypotonic
• Solution C: Isotonic
