VCE Biology Question Thread

[Rishi97]

So what works for you, but this is what I did in the bio exam. First, I flipped through the entire exam very quickly, because this helps to calm myself down (as I realise the qs are not too hard). Then I do as many multiple choices I can in my head and fill in the answers to multiple choice as soon as reading time ends. Good luck!

I know this is a pretty vague question, but how often did you study for biology in a week?

It really depended on how much work I had for my other 3/4 and other 1/2s. But I would say that for every bio lesson I had, I did (a minimum) of about 1 hour h/w and revision if not a bit more. Sorry, that was probably not the best answer, but it really depended on how much time I had to spare Good luck

Will an individual have either an ABO blood type or Rhesus blood type or both?

Just a bit confused.

Thanks!

When did you start doing unit 3 practise exams?

Thanks
When did you start doing unit 3 practise exams?

Pretty much as soon as I finished unit 3 at school.

Why enzymes are denatured in PCR??

[nerdmmb]

What is a diploid organism?

[Rishi97]

What is a diploid organism?

Refers to an organism with a paired set of chromosomes

[Reus]

What is a diploid organism?

An organism with two identical sets of chromosomes

DNA polymerase would denature during PCR because of the high temperature required to separate the strands. Therefore taq enzymes (which have a much higher tolerance range) must be used.

I'm quite a few if not all do biozone? If that is the case, I was set a whole chapter of biozone questions to do.
Which I did But in all honesty, I don't have the answers for them, so how do I know I'm correct? (as a class, they don't get corrected)
Was it all a waste of time?
And by any chance, does anyone have the answer pdf/sheet for biozone? Or is there no such thing haha

Thanks for that!

Just a bit confused.

Thanks!

Both: they are different groups of antigens. Rhesus is the positive or negative of your bloodtype. Eg A+ describes someone with A from ABO and that is 'positive' for the rhesus ag.

A chromatid is a single copy of a chromosome prior to cell division and is paired with an identical sister chromatid, whereas a chromosome is not paired.

Is that right?

Is that right?

Not really. A chromatid refers to a single molecule of DNA in its chromosome form. So you got that pretty well right. After DNA replication, you get a chromosome with two chromatids. Before DNA replication, you still have a chromosome but with just the one chromatid (it's rare to call this a chromatid though)

[grannysmith]

So there isn't much of a difference? Just that a chromatid is single duplicate whereas a chromosome can be both single or composed of two sister chromatids?
