Biology Exam: Answers and Discussion!

Me again! (girl who posted up the exam - soz vcaa)

I'm so sorry for not getting back to everyone's messages, I haven't been at home all day. From what I heard from the mods the files have been re-uploaded, so everyone should be able to access them. As to how I got the exam, I got a couple of friends to distract the assessors before I tackled the main one who had the spares - nah kidding, I just asked them after the exam and they gave me a spare copy haha 

Just wanted to let you guys know what was going on from my side, since everyone was being super nice in their messages

Hey for the CTP question, would it be okay to say something along the lines of  when CTP is in high concentration, the repressor protein would bind to the promotor to stop ATCase(?) production? I had written that CTP would bind to the ATCase enzyme but later crossed this out . . .

I thought it was natural disaster because there was only one genotype in the population that survived. It couldn't be migration that only that genotype migrated could it?

The question specifically referred to founder effect, which is caused by migration.

Overall I found the exam pretty good. MC was very easy (I hope, or else I'm absolutely screwed) and whilst a few short answer questions threw me off (how da fuck do you draw an amino acid) it wasn't too bad.

I wrote that it changed the shape of ATCase rather than stop ATCase production.

Can someone please explain question 36? About the geological timescale? I don't get why it's A. I put down C, anyway.

I think it's because the time periods shift based on milestones, for example, one period there are dinosaurs, the mass extinction of dinosaurs is what shifts into the next time period, so i put A.

When you see the places where the trilobites go extinct, it's always around where the geological timescale changes name. So it has to be A. Either that or your teacher taught you that.

Here is a link to the Short Answer section of the exam which I've uploaded on Google Drive.

And this is the link to the MC section which I'm pretty sure has been reuploaded anyway, so this is just for convenience.

Hey guys, I just did my own rough marking of the exam, and I got around 80-85%. I got high A+ for my sacs. Does anyone want to estimate what I may get?
I'm not too please with my exam but am hoping to get 38-40, do you think these marks will get me that?

They should do, but there's really no use speculating; it's out of your hands now Just be happy with the effort you put in and hope that the VCAA Gods are kind to you...

I remember when I did bio back in 2011, it was WAY easier

Slowpoke here, is there a copy of the short answer questions floating around somewhere in these 20 pages?

Maybe

Hey guys. Speaking from a too unrealistic and overly optimistic point of view, how many marks can one afford to lose if they want to get a 50?
