Reputation: 1571. E-filed in Early February and it took about 7 weeks to get my refund. It might have something to do with the amount as well. I got back $1,500 from the state which is probably more than most people get, so it could have taken longer for the larger payment.
Diffusion and Osmosis. Diffusion. -the process by which molecules spread from areas of high concentration, to areas of low concentration. Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient, toward areas of lesser concentration.
Best Answer: Diffusion is movements of particles from a high concentration to an area of low concentration, this happens with gases in the air, it also happens inside of cells this is how things travel in and out of cells when from when they are at a low concentration to a high concentration.iffusion is the concentration of solute (something dissolved in water) moving along a gradient. That is to say, if there is an area with a high concentration if will move more and more solute to the area with lower concentration until it about evens out.
