When protein channels allow for this process to occur, its "facilitated" form results, which is type of passive transport.
One form of this process is characterized by a non-linear dependence of particle MSD on time and is the subject of CTRW models. In plasmas, electrons move perpendicularly to magnetic field lines in a form of this property named for Bohm. The rate of this process in a gas is proportional to the square root of the density of the gas. The flux due to this process is related to the negative (*) chemical potential. When protein channels allow for this process to occur, its "facilitated" form results, which is type of passive transport. Fick's laws describe this process, and when water is subjected to this process, it is called osmosis. For 10 points, name this process by which molecules flow from areas of higher concentration to areas of lower concentration.
