To solve the osmosis word problem, let's break it down step by step based on the information provided. ### Known Conditions: 1. The problem involves facilitated diffusion and osmosis. 2. The context suggests a comparison between the concentration of water inside a cell and in a surrounding solution. 3. The solution is described as "icotonic," which seems to be a typo for "isotonic." ### Step-by-Step Solution: **a. What is the concentration of water in the solution:** - In an isotonic solution, the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell. Therefore, the concentration of water in the solution is relatively high, but we need to express it in terms of solute concentration. - If we assume the solution is isotonic, the concentration of water can be approximated as being similar to that inside the cell. **b. What is the concentration of the water inside the cell:** - Similar to the solution, in an isotonic environment, the concentration of water inside the cell is also high and equal to that of the surrounding solution. **c. Which way will water move:** - In an isotonic solution, there is no net movement of water. Water molecules will move in and out of the cell at equal rates, so the answer is that water will not move in a specific direction (it remains balanced). **d. Will the cell shrink, swell, or stay the same:** - Since the solution is isotonic, the cell will stay the same. There will be no net gain or loss of water. **e. What type of solution is this:** - The type of solution described is **isotonic**. ### Summary of Answers: a. Concentration of water in the solution: High (equal to inside the cell) b. Concentration of water inside the cell: High (equal to outside the solution) c. Direction of water movement: No net movement d. Cell behavior: It will stay the same e. Type of solution: Isotonic If you have any further questions or need additional clarification, feel free to ask!
