hi, i'm a recent applicant applying for the undergraduate science programs in this coming fall 07. I'd like to ask if anyone could give me some advises in choosing a major to get in? I'm interested in biochemistry, health science and genetics stuffs. Which courses are hot in York Uni? and less-competitive to get in? I know the biochemistry course is highly competitive to enrol, so what are other alternatives? Biology or chemistry? There aren't many choices to pick though. Any advises in the future career aspects in this field would be much appreciated too! thanks!

There are many creatures on the earth, with a wide range of intelligence levels. Isn't it possible that there are some that exist, that might be more intelligent than humans. If, as some scientists claim, we evolved out of the sea, isn't it possible that humans have already evolved beyond what we consider humans? Are we the top of the line?

Marginal revenue. A defense attorney charges her client $4000 plus $120 per hour. The formula R = 120n + 4000 gives her revenue in dollars for n hours of work.
