AQA BIOL5 Biology Unit 5 Exam - 22nd June 2011

me toooo

Well I thought that mean conc. of RNA is decreasing at start because RNA was being used for protein synthesis to help growth of pupa. Then ad it got older RNA conc. increased as less was being used as it was almost an adult pupa.

as long as you wrote good...im pretty sure thats more than enough...would have helped if you did a physiological process like cardiac i think but you should still get 20/25

I went into loads of detail i think.. (i did unit 4 in june :tongue:

), so i wrote about each stage of the calvin cycle, with rubisco enzymes and NADPH and stuff.. and also in as much depth for respiration + all the ammonification stuff for the nitrogen cycle

Right im confused about the question where it asked you which ratio of growth medium or somthing like that you would use to grow plants using tissue culture, The only square with just plantlets in was with the ratio 50:10 so i therefore put 5:1, But there was test where they used 5:1 ratio but there was no effect ? was it because there wasnt enough ? but surely the ratio is the same ? hmmm

- i got that and so did loads of people dont know why but think its right

What did everyone get for the question about how many cuts a restriction endoneculase makes.

my thoughts cos i need to get it out my system....

WHERE WAS UNIT 5?! there was SOME references ... but that 4 marker on enzymes and some other questions i probably could have answered without doing revision at all! it was guess work :frown:

and i HATED the restriction mapping one...was already weak on that subject so not surprised i missed out 3 questions or so :frown:

BUT the essay made up for it. i wrote 5 cycles: carbon/muscle/calvin cycle/DNA replication and cardiac cycle. anyone else write 5 paragraphs and left it at that? cos some of my friends somehow wrote 7/8 CYCLES :eek:

hope all of yours went well. and if i fail...which i probably will...then atleast i'll help the grade boundaries to be low for us so it wont be THAT bad :smile:

I did 10 cycles :tongue:

had over an hour spare after answering all the questions, can't hurt to show what ya know, I hope :tongue:

the cycle question was a godsend, but me being the idiot i am missed out cell cycles D: i ended up writing about krebs,nitrogen,predator prey,carbon,menstrual and light independant

the rest of the paper was a total failure, i couldn't remember half the stuff and some questions...the iguana and body temp one? why did rate of o2 increase?!

i hope the grade boundries somehow save me...

cause temp increased and hence rate of respiration will increase hence more oxygen uptake..also bout enymez work better at higher temp

guys what do u think grade boundaries will be like?

same as last year?

or higher/lower?

I think pehaps higher, first papers always seem to have lower grade boundries. Though a lot of people seem annoyed at the lack of bio5 content, so if a big enough fuss is made it may influence them to drop it slightly.

AQA have such a record of making biology papers with HSW questions all over the place though - is anyone really surprised we got this?

It could definitely have been a nicer paper, and after all I learned about muscles/neurones etc, I was annoyed we didn't get a question on that, but honestly, my main reaction was "oh, so they've given us a load of graphs again" rather than "omg those bitches i hate this paper".

But anyway, does anyone know if giving examples of genetically engineered crops (like Golden Rice, which I went into specifically (thankyou CGP revision guide!)) would be enough for breadth of knowledge? It was pretty much the only thing I got in that could be, since I kinda got into panic "just write as much as possible" mode for the essay and didn't think tactically.
