. DRAW IT An artificial “cell” consisting of an aqueous solutionenclosed in a selectively permeable membrane is immersed ina beaker containing a different solution, the “environment,”as shown in the accompanying diagram. The membrane ispermeable to water and to the simple sugars glucose and fructosebut impermeable to the disaccharide sucrose.(a) Draw solid arrows to indicate the net movement of solutesinto and/or out of the cell.(b) Is the solution outside the cell isotonic, hypotonic, orhypertonic?(c) Draw a dashed arrow to show the net osmosis, if any. (d) Will the artificial cell becomemore flaccid,more turgid,or stay the same?(e) Eventually, willthe two solutionshave the same ordifferent soluteconcentrations?
Diffusion and osmosis classification Classify the following characteristics based on whether they are describing diffusion, osmosis, or both. Diffusion Results in an Can occur with equal distribution of solute molecules or without a membrane Always involves the movement of water Requires a semi-permeable membrane Osmosis Involves the movement of gases, ions, and small water soluble molecules Passive form of movement that requires no energy Moves from areas of high concentration to low Both Diffusion and Osmosis Responsible for gas exchange in the lungs concentration A 3 of 15 Next > Cation to open the document "Epicinstaller-13.0.0-fortnite-a8e4f12cada646caa706d8be407be69f (3).msi". tv 22

DO NOT COPY THE ANSWER FROM THE SAME QUESTION. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions:a. No solute will exhibit a net diffusion out of the cell.b. Glucose will exhibit a net diffusion into the cell.c. NaCl will exhibit a zero net d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.
