Diffusion of Cell Size 2012 Kayla Szabo Loxton High School 2/20/2012 Rate of Diffusion Practical report Introduction: Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Cells need to utilise diffusion to exchange materials from outside of the cell to the inside of the cell for them to survive. Diffusion is a passive process‚ which means it doesn’t involve the need of energy. For a cell to survive it relies greatly on its size

9.5.2.4 Use available evidence to suggest reasons for the differences in the range of electromagnetic radiation detected by humans and other animals: Reasons for differences in detection between humans and other animals: The differences between human detection range and other animals detection range relates to their environment in which they live in and their way of life. The detection out of the visible spectrum is usually an adaptation for survival of the organism. Humans detection
