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.
Osmosis is a type of diffusion. Diffusion is where molecules spread out until they are evenly distributed in a medium, such as the air. The cell wall gives shape and structure to the cell. Inside all living cells, including bacteria, there are one or more chromosomes. These chromosomes contain all of the genetic information needed for the cell to stay alive and carry out all of the things that a cell does.
