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.

If someone can upload a copy of the exam - I can have a look at it and do a couple of solutions here and there too

[LPadlan]

Did everyone say c, for mc q13? It took me a while to get to that conclusion

[bingoman2000]

Likewise, I'd be happy to take a look too.

Which question was that? I don't remember all the numbers.

OMG I so feel it's like they ran out of questions like what happened to apoptosis, signal transduction, photosynthese and cell two and translation or translation. There were so many better questions was so pushed for time because it was so wordy!!!

For the question with venom inhibitors, could you say it was humoral immunity?

For Q13 I got D because below 10 arbitrary units, the rate of aerobic respiration would be higher than photosynthesis because more oxygen is being used than produced.

omg on that question asking why one gene could produce multiple proteins, I've realised the answer is probably due to exon splicing. Do you think I would get any marks if I mentioned the actions of regulatory genes affecting other gene's expression?

Depends on what exactly you wrote. Probably not. I knew straight away it was talking about exon splicing because I read it in another exam...there seemed to be lots of questions only slightly reworded from past exams.

if that's the question I think it is then I'm pretty sure that's what I picked too.

For the question with venom inhibitors, could you say it was humoral immunity?

If you’re asking about which part of the immune system it was from, I said innate immune system because it also talked about cytokines and lysozymes

[JaeSunRyoo]

Pretty sure it would be D, since past point T (or whatever point it was) the 02 rate was negative.

I can't remember what option c's answer was, tho.

There were a few questions that trundled me, like the one about the two control variables. I kinda feel like an idiot for not having answered that question satisfactorily, and realizing that one of the control variables I put in had already been answered by the question when the guy measured the O2/CO2/temperature for 4 mins without the cockroach in it.

Other than that... it wasn't too bad.

Can you say amount of food coackroche consumes before testing each day and the same type of food consumed for two controlled variables?
