AQA BIOL5 Biology Unit 5 Exam - 22nd June 2011

I put 75% 0 0 because the second curver was at 2 at one hour as well =/
For the lysosome question I wrote that lysosomes have enzymes for when the the body is broken down? Feel so stupid now xD
For the ratio I put 5:1 but I have no idea where the second mark is coming from!

Goodbye Chester :') Haha

OMG I HATED THE PAPER. Either it was bad or i'm just stupid I didn't want to do the DNA essay cause my DNA stuff was all muddled up, I did cycles instead, but I only did 3. I hope it's alright though

I got 5:1 for my ratio, Did anyone else get that?
and i got 100% 0% 0% idk why, i just did. AHHH. That paper felt like a unit 4 paper, it was all about application which is what it's supposed to be but still! I thought there'd at least be a few things that were straightforward.

I think i'm just dumb in biology then,

In the cycles essay when I was talking about the cell cycle I wrote about how in Synthesis stage of interphase DNA and histone protiens are replicated, then said histone proteins are associated with dna to form chromatin, and abit later said that small sections of the cytoskeletion called centrioles are used to mobolise the spindle fibres pulling apart the chromosomes during nuclear divison.

Will this be counted as outside the spec as we dont learn about the cytoskeleton, centrioles or histone proteins I dont think???

That mapping question may have well been written in Greek or some ancient language. WTF honestly. That 2nd question on the restriction mapping page actually made me laugh because it was so ridiculous.

I feel like AQA violated me. ):

What was that question on partial digest of the DNA ??

What was the question again...!?

Exam was terrible :/ there were so many little topics which i had been over but not bothered about too much and concentrated on the big stuff like impulses nerves muscles etc. And what comes up? The frikkin one line worth of topic in revision guides!!! Damn AQA! im so worried and upset now and really demotivated for chem..what a waste of revision :/ i did cycles essay, i wrote about resp, PS, carbon and nitrogen cycle..i mentiomed about insulin and glucose but didnt know whether that was a cycle so wrote it briefly and now regret not writing more! Hope the cycles are enough though otherwise fail I couldnt think of anything to do with AS and so wrote a quick paragraph on water into plants. Didnt have time so mentioned transpiration and predator pray cycle in my plan, hopefully theyll mark that too...Also, i wrote about haemoglobin and how it associates and dissociates O2, will that count as cycle? And in the essay could we write CO2 rather than carbon dioxide? Thanks

It showed a plasmid they'd put DNA in I think and then used to restriction enzymes to digest it.. That was so complicated, some people in my exam left that double page blank :|

where we meant to know what plantlets or callus were? I never heard of them, so I didn't even know what to put - though you needed all of them

essaY was good!
questions were awful
i put 100% 0 0 lol what an idiot!
didnt understand any of the pupa stuff/lysosomes etc
and probs got 0 on the restriction mapping!

hopefully essay made up for it need an A!

Also just so people know, for the question where they asked for the percentage for nervous stimulation of gastric juice the first one was 80%. I'm sure it was because for hormonal control it was at 2 and for nervous control it was at 8. So 80%. Not 100% sorry.

What did people put as their outside knowledge in the Cycle Essay??
