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.
Diffusion is the process by which small particles move from a place of high concentration to a place of lower concentration.By diffusion, small molecules like salts can go inside a cell from the outside. To keep itself alive, a Cell needs to take in many things from its outside.In Photosynthesis, gaseous Carbon Dioxide (CO2) enters the plant cell by diffusion. CO2 is very important in building food and making energy for the plants.y diffusion, small molecules like salts can go inside a cell from the outside.
