Well, I'm going to have to be direct with you, this forum doesn't give out free answers to homework problems. It's not fair to other students, nor to you, on an upcoming exam, or later on in practical life.
Furthermore, some schools can get litigious, and I'd hate to see Mitch: lose his board to legal fees
Besides, it's very boring for us, to go reread a basic text, or do a Google or wikipedia search, just to do your writing for you. Many of your questions are simple definitions, that you could find in your textbook's index, and I normally suggest you do that bit yourself, and come back with questions that are really stumping you.
There is also a rule on this board, not to demand urgency from us -- it is up to you to start your assignments early enough to get your work done, even with our help.
Thing is, you already know all that. And have basically said that in one week, you've lost all knowledge, and have no ability to recall it, or search for it. There is nothing I can do to help you, in that case.
Try some searches, and see if you can attempt your work, and we'll see what hints we can give you to help you with more confusing points.
