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.
The three types of diffusion in an independent cell are simple  diffusion, facilitated, and active. The function of simple  diffusion is to transfer oxygen. Facilitated diff â¦ usion transports  water or non polar molecules.Active diffusion transports materials  against the concentration gradient.he function of simple  diffusion is to transfer oxygen. Facilitated diff â¦ usion transports  water or non polar molecules.
