The response earned a final point for the discussion of the ability of water to moderate temperature: water creates an environment for stabilizing temperature in relationship to its specific heat sample: 3c. Water serves as a reactant and a product in the carbon cycle discuss the role of water in the carbon cycle c discuss the impact of one human activity on the water cycle.
To test how water potential, in a solution, affects the movement of water in and out of a cell by osmosis prediction i predict that by increasing the water potential around the outside of the potato cell, (ie so that the water potential is greater outside the cell compared to the inside of the cell eg 0m sucrose) that the net movement of water into the cell will increase. Using artificial flowers to investigate potential negative effects of increasing caffeine concentrations in nectar on the number of floral visits by bees identify.

Because of a cell's aqueous environment, it allows water to pass by osmosis or aquaporins with osmosis, water can move throughout the membranes of a cell, down its concentration gradient water moves from areas of high potential and low solute concentration to areas of low potential and high solute concentrations. Ap biology lab 1 ross lordo introduction questions 1 the solute potential would be -248 if the concentration inside the cell is 15 m, then would diffusion out of the cell and into the solution of 1 m this is due to water potential and the tendency for water to move from areas of high water potential to low water potential 2.
