when it says what evolutionary process, it is asking for natural or artificial selection only, or is it asking for divergent/convergent evolution

Natural, artificial, drift (that would be my guess)

How much do we need to know in terms of rational drug design?

Probably just how a drug can be produced with a SPECIFIC COMPLEMENTARY shape to a substance or part of the substance (pathogen/enzyme) to inactivate its function :)

Hey, I am doing bio next year and I am reading ahead. Do you recommend that i do checkpoints throughout the holidays whilst I learn material or should I save the checkpoints for next year?

You can probably do the chapter questions, and leave the VCAA ones for later.

And that they're designed to target a specific enzyme so as to kill a microorganism/cure a disease. The whole point of rational drug design is that you find a particular enzyme target and then knock it out by inhibition.

Yeah try and do as much as you can during the holidays, trust me DO NOT 'SAVE THEM'!! That's what I did and I really wish I had done them progressively throughout the year because although it doesn't seem like it, there are soooo many questions in that book!

Or alternatively you could do what grannysmith suggested, and then do the past exam questions as you do each topic during Unit3/4 to prepare for your SACs on the respective topic.

Whatever you learn now (before you start school next year)
make sure you learn it really well.  I CANNOT STRESS THIS ENOUGH.
There's really now point racing through it, and then having to relearn it later on. It's a waste of your time.

As for checkpoints. Do them if you feel like it. Definitely not essential though.
The advantage of doing questions is that it helps you in answering questions succintly, with the right wording. Examiners are very pedantic about this, so starting early will definitely help in that regards.
Although I find doing questions 2 weeks before a SAC more than enough time.
You really don't need to go overboard. Just make sure you keep up with class, and you will be fine.

Do we need to know about cellular respiration in plants and bacteria?

Do we need to know about pyruvate oxidation?

Hey all, I was doing the 2010 VCAA EXAM (U3) and I had a bit of trouble getting my head around this question (Q.2). The answer for the hypothesis states that "Mice fed hard pellets will weigh more than mice that are fed soft pellets", but wouldn't it be the other way around as the mice fed hard pellets would have less energy retained?  :o

Oops didn't read the bacteria, don't think we need to know that, just plants.

I just did this exam an hour ago! If energy is retained this means the breaking down of the food is possible/occurring hence weigh less. As the difference retained is indicated by the weight of mice.

Certainly not bacteria, mainly because they're a lot more versatile than plants and animals (aerobic respiration and photosynthesis are both bacterially derived traits/mechanisms)

Nope
