Science & Mathematics - 29 August 2007

I'm in a university science class called Living on Earth, and for the semester, we are required to do written research, conduct or at least propose an experiment, have about ten credible sources and one "junk science" source. We have a total of four projects throughout the semester on this one subject, three written and one oral. The instructor said we could choose anything as long as it is related to life on earth. I'm not looking for someone to do my assignment for me, but this is a broad subject and I am not scientifically minded. It's just such a broad field that I am having trouble choosing a subject and we are supposed to narrow it down as far as possible. That is, not have more than one very specific experiment going on for the subject.

Does any one know the dbSNP identifier (i.e. the rs number) for the Factor V Leiden mutation? I know it's commonly reffered to as G1691A, but I'm trying to be precise and the best way to do that is to use an rs#. I find it really hard to believe that it's not annotated in the database.

Hi there! I'm sure that this is pretty simple, but regardless, I'm not really sure where to begin. I'll give 2 examples of the kinds of problems that I don't know how to solve. If you could please tell me HOW to do it and WHY you're doing each step, rather than just the answer, that would be great because I have the answer key already... I just don't know how you arrive at the answer. :) Thanks!

(sin x)^4 - (sin x)^2
--------------------------
sec x


and

(cos w)(sin w ^2) + (cos w)^3
----------------------------------------
sec w


Thanks again! I'll pick a best answer TODAY!

Putting nanobots inside someone's body blows my mind! I can't help but think of the movie Matrix. I realize there are many other uses these little suckers and that's great. It just makes me uneasy!

What do you think?
