VCE Biology Question Thread

That's right (Y)

You can have multiple copies of the same allele on each chromosome though too But it will have another copy on the other.

Awesome thanks

For part d.) of this question (from VCAA 2011 Exam 1) the answer requires you to state both of:

- The baby would receive natural passive immunity from the mother as antibodies would be passed via the placenta/breast milk.
- After birth, the babys immune system has TLR's stimulated and would therefore not attack self-cells.

But I don't really understand the part about the baby receiving natural passive immunity. What is the baby receiving passive immunity from? The probiotic bacteria? How would this prevent an autoimmune disease?

:/

Any help would be appreciated

Thanks scooby!

Just did the 2013 exam and got 100/110... I don't know if I should be happy haha

That's a brilliant score. There were elements of that exam that were particularly challenging.

Incidentally, I just did 2013 last night

In order to get a study score of 40 or 40+, what should one get out of 110 on their exam?

I've done less than 30 exams altogether and that worries me :/

Thanks! What are the chances of them applying similar questions for this year?

Haha how'd you go?

You don't want to lose more than 8-10 marks through out the paper. Also depends on your rank and cohort

Calm down, I've only done 15

Don't you just need an A+ on the exam for a 40 (with a high ranking)?

[sparkyblossom]

How do you find out your ranking in the first place?

Ask your teacher

Not necessarily. You could be on the end scale of a bare minimum A+ which won't suffice a +40SS. However they are marked twice, so I don't know if its 8-10 marks on both of each haha. (My lecturer explained it quite well I just cant myself haha)

Hmmm it's relatively likely I think. There should be no reason for them to change things up significantly.

I got 109/110

That's slack, what question you muck up on?

Also I guess your result puts VCE Bio in perspective ahaha

Yeah.

I'm pretty sure a low A+ correlates to a 40 - top 9% of the cohort isn't it?

I think you've read the grade distribution wrong Reus. It says you need 186 marks out of 220 to get a A+ (a 40). It's out of 220 marks because its marked twice, so one examiner could give you 92/110 and the other 94/110.

You could have afforded to lose 17 marks on last years exam to get in the A+/40SS range.

They describe two completely opposite things:

- Homologous structure: Similar morphology/anatomy/genetic composition and development patterns (in some cases) BUT different function;

- Analogous structure: Similar general function, BUT the morphology/anatomy/whatever of the structure in question is different.

Hope that clarifies.

But a bats wing is both homologous and analogous to a birds wing? They have homologous bones but the wings are analogous.

The style of question is similar I guess. That's what I mean there. They'll pull things from different areas, but the way they ask, the level of detail, and indeed the emphasis should all be the same. I personally felt as though they actually were being a little more intense with detail at times. There were less tricks, and a lot more recall.

Well, Biomedicine is completely human-based biology, so a question on photosynthesis of course :p I didn't think through NADPH properly and think I switched it with NADP⁺. I merely took photosynthesis as aerobic respiration in reverse where in many ways it's not.
