Para/por, es/esta

Are very simple questions looked down upin here? I feel like a nuisance, and I don't want to be that way.

I'm a beginner and I'm slowly making my way through Duolingo, on day 13. And there are two points that I haven't been able to find the answer to. I have Googled it several times but I do have a learning disability and it's possible that I'm just not "getting" it. I'm not sure how much is due to my learning disability and how much is because it is simply confusing to a native English speaker.

ONE: What's the difference between para and por?

TWO: What's the difference between es and esta?

Sorry for such basic questions! I have tried to find the answer and just gotten more confused because I think all of the answers are over my head or too in-depth. Thank you very much.
