### #98593Past paper - help

Posted by on 27 May 2007 - 03:34 PM in Chemistry

Technetium-100 has a half-life of 16s. If a sample of technetium-100 is left for 48s, what fraction of the sample would remain?

it tells you the mass of technetium is 100, it also tells you your leaving it for 48s that makes it 3 half lifes ( 3 x 16)

Make sure you dont just divide 100 by 3 though it doesnt work like that. The sample halfs, halfs again and then one more so youve got:

100g to 50g to 25g to 12.5g To get your fraction you simply do : 12.5g divided by 100(mass you started with) which gives you 0.125.

Hope thats clear im not so good at explaining hehe

Posted by on 27 May 2007 - 12:57 AM in Biology

i was just browsing this topic, weirdly enough i also did a yeast investigation.

Mine was to investigate natural vs. medical remedies for eliminating yeast cells.

I suppose a few of those will be marked then hehe, thats so strange i thought mine was pretty unique...clearly not

### #98382Exam 2007

Posted by on 23 May 2007 - 02:55 PM in Biology

I dont regret taking it, the course covers a lot of areas that interst me espcially the units covering cell cycle and cell culturing, however it did suck with the amount of problem solving but no reason not to take it cause thats only in the exam.

its a good subject to take but maybe not if you had to get a good grade in it

Posted by on 21 May 2007 - 08:20 PM in Biology

Hello! first time ive ever posted, however i have recently been reading topics and such

I thought the first section B question was pretty tough? not much knowledge at all and im rubbish at problem solving

although the essays were ace ... overall i think i passed ..and thats good enough for me.
