It senses when your body’s temperature is too hot or cold. When your body is too hot‚ the hypothalamus senses that a change needs to be made so to reverse the heating process‚ thus reducing the amount of blood that is being sent to that area. This same action will cool the body and return it to a normal temperature. The ways in which

Surface Area to Volume Ratio and the Relation to the Rate of Diffusion Aim and Background This is an experiment to examine how the Surface Area / Volume Ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen
