what do we have to write about brine shrimp

get on msn matee! and also, stevie mentioned something to do 40 or so brine shrimps.. place in salty water.. NOT tap water because of the chlorine content in it meaning its toxic.. and using a torch of some sort as it is attracted by light.. and yeh. all i could remember. pointless practical.. oh, and also they are invertibrates i think, meaning you have to be careful with them as no nervous system, cannot feel pain etc. Also, something to do with being gentle with them.. ethics.

anyone got the specimen paper unit 4 mark scheme! desparate !!!

I think you're talking about this?

AWESOME!


Thanks

Maybe something about xylem for dendrochronology (uh... did I even spell that righ? :s)
Possibly something about what the sugars can be turned into etc.

Most likely something about transcription and translation for the forensics stuff.

But don't take my word on it, I'm just guessing. ^^

How much biology can one learn in 5 hours? :P

just finished my revision. night!

I thought the paper was quite good, although the plant mineral question completely threw me.. Ended up guessing starch and nitrates..
I actually think the graph interpretation stuff was a good way of combining the stuff we'd learnt, rather than just spouting out things we'd memorised.
oh well.. Time to revise chemistry
