Â· Temperature affects osmosis, because the greater the temperature, the greater the energy (which must be heat), the faster the molecules under the influence of the heat will move, and the faster they will diffuse across the membrane. This isn't the only worry, because heat can have a physically detrimental affect on this experiment as well.
The hypothalamus of the brain works as the thermostat for temperature control inside the body. Throughout your body are temperature receptors that send feedback to the hypothalamus.If the hypothalamus receives indication that the body is either too hot or too cold, the brain will signal the body to react.For example, if you are outside on a hot day, temperature receptors on your skin will signal the heat to your hypothalamus which responds accordingly.hermoregulation. The body regulates its temperature by means of convection, conduction and evaporation. Convection is the change in temperature due to the movement of air or water over the skin, for example, a breeze while you are running.
