Membrane Permeability Objectives: 1. Define solvent‚ solute‚ solution‚ selectively permeable‚ diffusion‚ osmosis‚ concentration gradient‚ equilibrium‚ turgid‚ plasmolyzed‚ plasmolysis‚ turgor pressure‚ tonicity‚ hypertonic‚ isotonic‚ hypotonic; 2. Describe the effects of hypertonic‚ isotonic‚ and hypotonic solutions on Elodea leaf cells and onion scale leafs. Introduction: Membrane permeability is a quality of a cell’s plasma membrane that allows substances to pass in and out of the cell‚ so that

) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than the water potential inside the beetroot cell. I predict that Osmosis

Actual Mechanism of Heat Loss during Exercise High heat and humidity reduce body’s ability to lose heat by radiation or convection and evaporation. While exercising‚ the heat production within muscle and it is transfer from the core to the skin. Under appropriate environmental conditions‚ excess body heat dissipates to the environment which regulates the core temperature within a narrow range. During exercise in the heat‚ the heat loss mechanisms compete with the active muscles for more of the
