VCE Biology Question Thread

[n.a]

Mine
1) STAV
2) VCAA
3) Everything else

Can't think of any other companies but the above should help you

Thank you so much ! 😊

Thank you so much ! 😊

Take note that VCAA exams are the most important exams you can do because they're pretty much the real thing. I just like STAV questions more, but that's just me

Oh yeah, fair enough, I was just looking for more exposure to questions because I want to save VCAA for last.

Hey guys! I was wondering if lipid soluble hormones bind to receptors in the cytosol or nucleus?

They can bind to either, depends on the hormone really.

do examiners take off marks for colloquiality? i.e Ribosomes are considered the working bench when synthesising etc....
i know ur meant to use lang. appropriate to bio, but is this still ok? ty ty <3

Just going to jump in and say that it probably doesn't matter, but as said, it's both. Typically the nucleus, but cortisol goes to the cytoplasm.

As long as you demonstrate an understanding of the concept. I'd try to be more technical though to be perfectly honest.

Is there a list of all the definitions we need to have memorised?

Hello once again,

I was just wondering what a sample answer would be for this question as VCAA haven't posted answers for the 2013 sample exam.

Thanks

Give it a crack first

Is there a list of all the definitions we need to have memorised?

No. You really shouldn't waste your time coming into the exam trying to remember lists of definitions either. Biology—and indeed any science—is nothing about definitions; it's about being able to describe concepts.

I did - when I did the exam I said that the binding of the hormone to the receptor may change the shape of the receptor over time, leading to the decrease in response.

I wanted to know what the right answer would be because my answer doesn't sound right.

Do we need to know in detail all of the steps of photosynthesis, aerobic cellular respiration and anaerobic cellular respiration? Like how each molecule interacts with the other to break it up and the order of those steps? Or just the inputs and outputs of each stage?

I'll acknowledge that it's a pretty shocking question. I'm not sure what answers they'd look for, because really, you shouldn't be expected to know and that'd mean anything is reasonable then.

Things that could be reasonable though:

-depletion of secondary messengers
-loss of receptors

Inputs and outputs are probably fine. They're not likely to ask anything more complicated.

For the inflammatory response, can we write mast cells release histamine which cause "vasodilation" thus attracting phagocytes to the site of infection etc..  Can i use the word "vasodilation"? Or do i have to write/Is it the same as writing: "...which cause 'arterioles to expand'.."

[hodang]

Also, am i allowed to write MHC Class 1 markers or do i have to write Class 1 MHC markers? Would the examiners accept both?
