Which example is one specific form of simple diffusion? if water moves into a cell by osmosis, it is moving into an area of higher water concentration. if water moves into a cell by diffusion, it is moving into an area of higher solute concentration. if water moves into a cell by osmosis, it is moving into an area of higher solute concentration. if water moves into a cell by diffusion, it is moving from an area of higher concentration to an area of lower concentration.

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.

Na+ loss through sweet plus the dilution has lowered na+ concentration outside of neurons, altering the na+ equilibrium potential. sodium exists more outside the cells than inside. when na+ is lost by sweat plus the dilution( because they drink a lot of water) changes the concentration outside the cell, forcing the water to enter the cell and attempt to balance the concentration inside/outside.the problem is that the abundance of water will cause the cells to swell. most cells can adapt, however, the brain cells can't that's why the runner has confusion and can't control the muscles.  if not treated and this occurs in less than 48 hours, it can be immediately fatal .
