Comparative study: foreign direct investment (fdi) and the while the relationship between economic growth and fdi is considered as a well studied subject, within . Because diffusion relies on movement and movement relies on the size of the molecule, there is a direct relationship between molecular size and diffusion rate larger molecules necessitate larger amounts of energy to engage in the same level of activity as smaller molecules. A naive interpretation of the relationship between these two kinds of crime rates might suggest highly correlated empirical realities however, this does not appear to be the case the social dynamics that drive changes in crime rate levels appear, in many cases, to be only tangentially related to the dynamics that drive shifts in fear and .

There is a close relationship between the opening of stomata and presence of light light affects the rate of transpiration in two ways firstly, light causes stomata to open. The lowered diffusion rate and the accompanying decrease in the speed of waste elimination would also cause the cell to be poisoned by a build-up of toxic substances because of the need to maintain the proper ratio between interior volume and external surface area, cells will reproduce rather than grow past a certain point. Charges (+-) usually slow diffusion through a biological membrane biological membranes have an hydrophic (no charge) interior thus preventing and molcules with a charge from passing through thus .
