This graph represents the results of an osmosis experiment using dialysis tubing models (DTM) to simulate cell membranes. The DTMs contained a sucrose solution and were placed in beakers with different concentrations of glucose Each line (A-D) indicates a different DTM. Use the graph to answer the questions that follow.   Diagram of an experimental setup of a dialysis tubing cell model to observe osmosisAssume that the change in weight in time is due to the movement of water into or out of the bag. Which DTM bag initially had the greatest concentration gradient with the solution in the beaker? Type the letter for correct bag in the space provided: [BLANK-1]   In the following spaces, indicate the correct environment each of the bags (A-D) was placed in based on the results in the graph? (One space will have two answers. In that case, separate the letters with the word “and”)   DTM bag(s) in an isotonic environment: [BLANK-2] DTM bag(s) in a hypertonic environment: [BLANK-3] DTM bag(s) in a hypotonic environment: [BLANK-4]
