If you are having a hard time remembering diffusion and osmosis I would recommend writing it down. Now if your issue is not remembering it but learning it, things are a bit different. So lets start with osmosis, H20 is the elemental name for water it has an O so H2O and osmosis go together. So in osmosis water flows from a high concentration to low. What that means is that if there is more water in one solution than the other on each side of the membrane water will flow towards the side with less water. So lets describe this more and less water I mean it is water it is all the same, right? Wrong, for example salt water has a lower concentration of water than distilled water. Well why is this you say, well that is because water is only the H2O, there are lots of other things in water such as salt and iron. If there is more of those other thing then there is less water. Now diffusion is different than osmosis because it deals with things that are not water. The concept though is the same, things will flow from high concentration to low. There are three types of diffusion: simple, facilitated, and active transport. Simple diffusion is when things simply pass in between the molecules in the cell membrane. It is simple so it requires nothing else for it to happen. Facilitated diffusion requires a protein to help thing pass through the membrane.
Facilitated starts with an f and fork starts with an f. You need a fork to eat food just as you need a protein for facilitated diffusion. Now active transport is a bit different. It moves things from a low concentration to a high. To do this it requires energy, which comes in the form of atp. Active transport basically shoves things into a cell. So when you are active you play soccer and in soccer you try and push the ball into the goal against what the defense wants.
Check out those examples:

Well it is a free post, so why don't I talk about something I find interesting. So I am going to go over my personal thoughts on windows 8. So off to the right there is a picture of the new "desktop" or metro it is called. Pretty nice new start up screen, it gives you live weather news and email and such right there. So first impressions pretty good. Now to the different things, because you might think the desktop is gone, but you would be wrong it is simply an program to run now. So now you run the desktop but there is a one big difference. There is no longer a start button, which is personally just strange. To access settings and such you have to put your mouse into the top right corner, which personally is not very intuitive. Also to get back to the start screen you basically have to do the same thing unless you know keyboard shortcuts. So thoughts on the whole desktop as an application, it just feels weird. If you just browse the web you will hardly use the desktop but if you are running other programs then you will use it much more and I feel that it is going to take some getting used to. Now onto to my favorites, aka the copy dialog box. It may sound like something trivial but it will be nice to finally be able to see how long it will be until something is done coping. Overall, I enjoy windows 8. Is there somethings that could be made better yes but when it comes out on tablets and computers it will allow a more unified experience over both platforms.
