VCE Biology Exam Discussion and Solutions

[LifeisaConstantStruggle]

Now I feel a little better that's what I wrote too. I'm so pissed about that and like 4/5 pages of experimental design. I knew there would be a lot but that's crazy. So many things they could have assessed.

Tbh yeah the experimental design stuff took the most time but it wasn't really unexpected tho the questions asked were quite predictable for experimental design (unless if you count the possible controlled variables then WOW)

And I wrote that the cockroach should be put in the chamber at the same time of the day due to probable difference in rate of respiration at day/night I wonder if it is correct or not : o

[JaeSunRyoo]

Would 45 megafauna already being extinct and megafauna was already declining in numbers before first Australians came to Australia be two distinct answers or are they kind of similar?

I wrote some stuff about the 45 megafauna already being extinct, but also had another point talking about how the presence of the wombat-like megafauna co-existing with the First Australians for 17000 years also meant that there were possibilities that the extinction model was incorrect.

It does seem a bit similar to me, though, what you wrote.

[James Holgate]

Hey everyone,
For megafauna I did;
•Fire plants didnt die out therefore megafauna eating them didnt die out
•Mega fauna going extinct before arrival of first australians
•Wombat thing and humans existing together for 17,000 years

For cockroach controls I did;
•Keep chamber air tight when putting the cockroach in to prevent gas exchange from occurring with the external environment
•Make the container small/restrict movement of cockroach—> if it moves more the rate of respiration will increase

All those hours of studying spent on apoptosis, signalling molecules, specific immunity, fossils etc etc and THOSE are the questions they decide to give us? Stupid study design and its stupid dot points 😢

Ikr I'm so annoyed. I crammed apoptosis because I didn't know it very well. No short answer on gene expression, apoptosis, acquired immunity...

But hey, some of it was on MC. A lot of things were still asked on MC.

Still, no short answers on those does suck...

What did people get for the question.About having low consequence of l something in the blood?  I put that it would lead to  the production of more cholesterol which increases chance of coronary heart disease ,I think my answer is wrong though 😂

Instead they just tell us to define sterile... oh well just glad it's finally over and who knows if everyone seemed to find it somewhat difficult it may scale up quite a bit? Because honestly looking at this years questions and last year's questions, 2016 was much easier in my opinion

[fluff]

does anyone know around how many marks someone can lose in saq to get around 49-50?

[rainbowsparkles15]

They gave us a 6 mark question that was about mass extinction of Australian MegaFauna. we had to read an excerpt of an article (something from The Conversation) and identify 3 points that provided evidence against the rapid extinction theory and why. It felt like an English exam 

After all those immunity questions people were asking yesterday, the only short answer questions were on innate immunity.

What did people pick for MC Q40? I changed my mind last minute.

Cannot agree more!! The short answer missed so so so many points I thought would come up: allergies, adaptive immunity, apoptosis, types of fossils, vaccines, BMP4 and master genes, monoclonal antibodies HIV/MS, signal transduction, a 'typical' natural selection/ speciation question, designing an experiment and so many more! Then we get asked to define sterile ((( Different to what I expected for sure

I thiiiink I put A for 40 but can't quite remember which q it was, what was it about?

seeing all that content being listed like that makes me wanna cry I studied all those things so intensely and dedicated so much time but no. For nothing   btw what was question 40? Also what did people get for question 39? Kinda confused my brain

[PhoenixxFire]

Question 40 was about the treatment of viral infected tobacco plants using a spray containing double stranded RNA. It was a bit confusing. Originally I picked C then changed to A. What was 39?

Copy of the exam still isn't up? 🤔

[PhoenixxFire]

Copy of the exams still isn't up? 🤔

Vox is going to put up answers sometime tonight

[K888]

Copy of the exams still isn't up? 🤔

It's happening soon. Should be up within the next few hours.

And as PhoenixxFire said, vox nihili will put up answers tonight.

Hmm, I thought he would only put up the solutions.
Hopefully he puts up copy with solutions then
