Edexcel A2 Biology Unit 4(6BIO4) 13/06/11 - OFFICIAL THREAD !

for amino acids 20 right nucleotides.

and what was the mathemitical Qs.

60 isn't it?

3 nucleotides:1 amino acid

20 amino acids --> 60 nucleotides

There was a question where you had to label the chloroplast for the LDR.

I labeled the Thylakoid membrane and thylakoid space

It's 60 isn't it?

3 nucleotides:1 amino acid

20 amino acids --> 60 nucleotides

I did not have a clue about scientists qu so I put down that it is not just burning of fossil fuels that causes global warming. I went on about methane and farming i.e. cattle and paddy fields and that biofuels caused problems carbon sinks removed etc


What was the two mark question on rigor mortis again?

and the question about the number of amino acids - the ape one
what did everyone put?

Abiotic Factors?

Lol i wrote abt the Temp of the Surroundings

And the Othr i just baffld .. Abt the ph of surrounding atmosphere where the body was kept

Fossil Fuel Q?

Was just Wondering whthr i WAS the ONLY candidate who actually wrote abt the Oil-funding companies Bribing the scientists lol!!! So they'd say Fossil Fuels dnt affect Temp
As these Companies need fuels lol

Hahah i ran 0ut 0f points!
It was 6 marks nd aftr writing abt all the C02 and Defoestation nd blah blah this was wht i came up wd nd it was mentiond in the Guide too! :/:/ -_____-

what factor affects rate of rigor mortis immediately after death?
- i put drugs in body??

also - the other abiotic factors - i put temp, and just guessed either age/activity before death but i cant remember which i stuck to...
either way theyre both non - environmental.

Came home in tears after this exam... had a 1hr 45min exam in the morning, came straight out of it with a huge migraine and went into this exam. I actually found this exam better than the one in January but timing was a HUGE problem did anyone else think that timing was an issue? I didn't have time to answer the last three pages, I had one minute to answer them. It's so frustrating because I know if I had been given more time... say if the paper was 2 hours instead of 1hr 30min then we could have all done so much better! and I hate the thought that it could jeopardise our chances of a place at uni

im going to write a complaint email to edexcel today about the timing of the exam and also about the content! I think that anyone who agrees should email too, the more complaints they have surely the more likely they are to do something or lower the boundaries more? Meh I don't know but it's worth a try...

I know I've failed this exam I didn't even know what globular enzymes are! I think I put that fibrous proteins are composed of fibres (LOL) and globular proteins aren't, then I put some absolute crap about the enzymes having an amine and carboxylic acid group and the fibrous proteins not. This exam has seriously F'd up my chances of going to uni cheers edexcel!!
