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

Which direction are the sodium and potassium bing pumped? How many sodiums are being pumped? How many potassiums are being pumped?
What we know about diffusion states that the concentration of ions inside and outside a cell should be thesame, but in a neuron, the concentrations of sodium and potassium ions are quite different. How does the cell go against the forces of diffusion?
The cytoplasm of a certain cell is composed of a solution that is 98% water, 2% solutes. Consider the solution shown in the beaker in this picture: FOOE OOS Foor solution. [Select] Cytoplasm is 98% water, 2% solutes. The solution in the beaker would be considered when compared to [Select] The plasma membrane is impermeable to solutes. Beaker solution is 98% water, 2% solutes the cell. We would expect that the cell would [Select] if it was placed in the would account for whatever changes might occur to the volume of the cytoplasm of the cell when it is placed in the solution.
