Why do people their homework questions on here? We can tell whether you're stuck on homework, or curious (all good reasons to post) or trying to sucker us into doing your homework for you. PLEAAAASE just read your text or search online before you resort to asking on here. I'd love to help if you're stuck and can't find the answer, but it's pretty clear some of you aren't trying at all. Anyone else annoyed?

Given the present state of biotechnology as it is, how much time do you think we'll have to wait before we have cybernetically-augmented people?

(Not counting artificial knee-caps and hearts, but actual cybernetic limbs, eyes, audio sensors, etc..)

I know the obvious reasons like it feels good, helps you feel closer to the object of your affections etc. But is it an instinct? It seems to come naturally, yet through evolution does it have any particular use as such (we instinctively know to 'mate' but this has enabled our species to continue, kissing seems extraneous)?

It says the atom's reactivity level depends on the amount of electrons since one type of element always has that same proton number anyways..

however, isotopes is an element w/ same number of protons but differnt number of neutrons...does that determine the reactivity too?

....can someone just clear that up for me?
thank you
