The Biological Question Thread

[cypriottiger]

well i gave my detailed explanation on cloning in the thread, i think u were there lol, so id rather not repeat.
stem cells come in 3 forms
totipotent- can differentiate into any cells (taken from 2-8 cell embryos)
pluripotant- can differentiate into most cells (taken from inner lining of embryos)
multipotent- can only differentiate into a specific cell (taken from adult bone marrow cells, adult stem cells)

you forgot omnipotent: Having unlimited authority or power and can differentiate into every single cell at the same time(taken from the awesomeness cells of a deity/god ).

lmao somebody's been reading 1984......
oh btw people, can someone link me to the thread with the vcaa 09 exam? i just did it and need to vent.

I think after the length of time this bio study design has been going for (since 2006) they realise what most common text books and teachers would teach and what they would not teach. Unless they wanted to be real assholes they wouldn't put something in there like cloning or nuclear transfer(hopefully..)

I think that's just the sort of thing they would do.

Nuclear transfer is rather simple, and has been in past exam(s). 

If they wan't to be assholes, there will be a question saying:

a) What is DNA sequencing?
b) Outline the process by which a DNA sequence is obtained

Our teacher said we don't have to know it so I haven't bothered to learn it.

[slothpomba]

I never learnt anything about it ... damn

i'm looking at the statistical grade assesment on vcaa for bio last year,
anyone get why it's out of 150?
if there are 90 marks...how...does this total to...150?
o.O

there are 90 marks for psychology, in regards to biology there are 75.
since the biology exams are marked separately by different teachers this becomes 150.
75 times 2 =150.

[masonnnn]

aaaha. ah i'm a fool. thanks

[masonnnn]

this also means 77% was an a+ last year...
i like that.
a lot.

that's sexy news.
btw did you do the umat this year?

[cypriottiger]

yay i got 88%

[masonnnn]

i was thinking a+ would be 90% so was a bit eh. so this is damn attractive, aha. 

and didn't do the umat actually. for undergraduate med i don't have the funds or interest to travel outside melbourne and monash as the only current undergrad degree is just too competitive.

also i'm not 100% positive medicine is for me, i have a huge interest in a lot of sciences and other things so i'd rather start out undergraduate and living the high life, then go after post-grad if i decide it's definitely for me.

oops, lifestory.

I like the thinking, and I think you will figure out what you really want to be.

[stonecold]

VCAA 09 sucked, especially the multi choice question about operons. 

Main evolution question was stupid too.

[stonecold]

Can someone explain Q7 from VCAA 2009.

I don't get where all these normal alleles come from, and won't the daughters DNA just be whatever colour that was used to stain it?
