Osmosis Aim: To determine the concentration of cell sap in a potato cell. Osmosis is the movement of water through a semi-permeable membrane. It starts from a weak solution and becomes a more stronger solution until the concentrations on both sides are equal. To investigate the range of solutions needed to find the point at which the surrounding solution is the same as the cell sap in the vacuole.

How does the kidney function: The kidney has two important functions for the body because it is connected to the body’s blood flow‚ it can help monitor blood pressure and secrete hormones‚ which can raise blood pressure in the event when it does not receive enough blood flow. However the most important job is filtration of blood. The kidney works to filter out toxins‚ especially chemicals that are formed as a result of cells using energy. The kidneys also work to maintain the balance of electrolytes

Diffusion and Osmosis in an egg Low concentration 1.1 Diffusion is the process of molecules spreading from areas of high concentration to areas of low concentration. High concentration 1.1 Osmosis is the diffusion of water molecules through a semi-permeable membrane from the area of low concentration of solute to the area of high concentration of solute. 1.2 Diffusion is important to living cells because it’s the way they take in materials from the environment‚ and they also prevent themselves
