How'd you go?

[Russ]

And Russ, don't even think about racing us - it's two against one!! What time do you have work?

I don't have to do plant questions, you can't win

Please explain...

Plant biology isn't real biology. I do have to leave for work though, you'll probably beat me

[HERculina]

o wat...
damn thats another question wrong.

for how antibodies work question i wrote it either coats bacteria attracting more macrophages, causes agglutination/precipitation of bacteria or lysing cell wall of bacteria. do i get marks off cause i forgot that complementary proteins actually do the rupturing part =(

it said he was 'hypersensitive' which is what iu wrote :S

[Jdog]

There was similar hype over last years exam and how hard it was, I doubt the cut-off will go below 59 and also VCAA rarely give two answers correct to one multiple choice question. I can't see them giving two in this case, since the only time I've seen them give two is when there is a problem with the way the question is worded and that it could be intepreted in more than one way. I haven't personally seen the exam so this mightn't be the case.

well done to all of you!

although I don't want to dissapoint you minus 3-5 marks from everything you think you got correct,  since examiners will take marks of for semantics. But on the bright side, you only roguhly two 69's for a 50!

[Russ]

If the question was to name antibody functions then yeah, you probably needed to reference the complement cascade for lysis

[Charmz]

So if you talked about inflammation, it would be completely wrong? 0/3 ?

Apprently inflammation had something do with it. but allergic responce is also correct.

Said it was a sensitivity reaction, not hypersensitive... but it could mean the same thing...

[supernerd]

hey guys, im tutoring a Bio kid  and was wondering if anyone has  a copy of the paper for me to look at so i know how she would have gone... also hard exam = easier A+ just quietly

Hey hey hey... The likes of you depend on plants for.. food and medicines and... chocolate!

"Here's how the poison ivy response occurs. Urushiol makes its way down through the skin, where it is metabolized, or broken down. Immune cells called T lymphocytes (or T-cells) recognize the urushiol derivatives as a foreign substance, or antigen. They send out inflammatory signals called cytokines, which bring in white blood cells. Under orders from the cytokines, these white blood cells turn into macrophages. The macrophages eat foreign substances, but in doing so they also damage normal tissue, resulting in the skin inflammation that occurs with poison ivy.

­The allergic reaction to poison ivy is known as delayed hypersensitivity. "

From the net. So an inflammation + a hypersensitivity reaction is involved?... Damnit ! I was tied between writing about either, should've written about both..

Question 9 didn't come out right so this is what it says
Antibodies passed from a mother to her baby during breast-feeding would be best described as:
A) naturally acquired, passive immunity
B) naturally acquired, active immunity
C) artificially acquired, passive immunity
D) artificially acquired, active immunity

And here's the link to the VCAA 2011 BIO exam enjoy!

do examiners give half marks in biology?
