haha agreed, these topics that overlap with other courses just makes life so much eaiser.tommykins said:<3howphysicscomplimentschemistry
I have seen different else where though, i think it was in kisstommykins said:Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate (PHA), a polymer belonging to the polyesters class that was first isolated and characterized in 1925 by French microbiologist Maurice Lemoigne. PHB is produced by micro-organisms (like Alcaligenes eutrophus or Bacillus megaterium) apparently in response to conditions of physiological stress.

They secrete it under a carbon diet. They eats loads of carbon and poos it outcrammy90 said:how exactly do bacteria produce it
do the alcaligenes eutrophus act on sugars?
or is on plant material :S
I'd like that.SkimDawg said:A nice beauuutiful 7 marker on radioisotopes would be nice. Im prolly gunna get shot for saying that.
Acid/base development would be good. The others you mentioned would also be sweet, except for batteries which suck.nandayo said:I think a good seven-marker would be the historical development of acid/base theory and the pros/cons with each proposed model. Hawww, that would be so sweet. I'm not sure if that's been done before.
Anything with acid/bases, Haber, radioisotopes and batteries would be fine. If it's on ethanol or biopolymers I'm going to be pissed. Although I have to say that the worst possible seven marker would be one on validity, reliability and accuracy.

I did the 2005 question involving the acid-base development last night, was shithouse. It was worth 5 marks btw.JasonNg1025 said:Same.
Acid-base development? The stuff about the 4 guys who said things about acids and bases? I think that was like a 5-marker at most... so yeah I'd like it if it were worth 7 marks
