Step 1
- The goal is to find a salt concentration in which the cell can maintain homeostasis, meaning that the cell neither loses nor gains water. - The internal salt concentration of the cell is 1.01 g/ml. - The table shows the salt concentrations for beakers A, B, and Show more…

Part I: Dialysis bags ("cells") are placed in three different beakers. The cells, as well as the beakers, contain different aqueous solutions of NaCl. For each of the beakers, answer the questions below. Beaker #1 Beaker #2 Beaker #3 Cell # 1 Cell # 2 Cell # 3 Cell # 1 contains 15% NaCl Beaker contains 35% NaCl Cell # 1 contains 30% NaCl Beaker contains 30% NaCl Cell # 1 contains 50% NaCl Beaker contains 25% NaCl Beaker #1: a) The solution inside the cell contains 15% NaCl and % water. b) The beaker contains 35% NaCl and % water. c) The solution inside cell #1 is tonic to the solution outside cell #1. d) The solution outside cell #1 is tonic to the solution inside cell #1. e) In which direction will water move? (circle one below) Into the cell Out of the cell No net movement of water f) Draw an arrow or arrows on Beaker #1 above to show the movement of water. g) Explain how you determined the movement of water. h) Over time, what will happen to cell #1? (circle one below) Shrinks Swells Remains the same size

Title: Understanding Osmosis: A Guide to Water Concentration and Membrane Permeability In the process of diffusion (osmosis), water molecules move across selectively permeable membranes from regions of lower solute concentration to regions of higher solute concentration. This diffusion technique is essential for maintaining equilibrium in living organisms. The difference in solute concentration on each side of the membrane is determined by the concentration gradient. The solution with a higher solute concentration is referred to as hypertonic, while the solution with a lower solute concentration is referred to as hypotonic. When the solute concentrations are equal, the solutions are said to be isotonic. To demonstrate osmosis, an experiment can be conducted using cellophane dialysis tubing, also known as "bags." Some bags are filled with water, while others are filled with a sugar solution. The bags are then placed in beakers containing either water or a sugar solution. The setup for the osmosis demonstration is as follows: Figure: Osmosis demonstration setup Beaker A: Water Beaker B: Water Beaker C: Sugar solution Beaker D: Sugar solution Bag 1: Filled with water, placed in Beaker A Bag 2: Filled with water, placed in Beaker B Bag 3: Filled with a sugar solution, placed in Beaker C Bag 4: Filled with a sugar solution, placed in Beaker D The initial weight of each bag is recorded, and after a certain period of time, the final weight of each bag is measured. By comparing the initial and final weights, the rate of osmosis can be determined.
