Look, you can't just go around asking questions like this. Nobodies going to do your homework for you. If you needed something explained, that's one thing, but deliberately asking for an answer, and taking it word for word is cheating. Don't do it! These are also not very challenging questions I can imagine, so I bet you could get this out of a textbook or internet, and write up your own answers.
Hope I could "explain", and I'm sorry I can't give you these answers, I don't want to take the time to answer them, and also for the reasons above.
