Just come out of the exam.. And let me just say, I THOUGHT IT WAS TERRIBLE!  :idiot2:

I actually did pretty well on the past exams too  :(

I thought it was alright, it was easier than last year's at least! Wasn't too hard or too easy - nice way to end the study design I reckon

What?? I thought that 2008-2010 were easy! This year's one: I opened the book at reading time, and i'm like "Oh shiiiiit"

There were some questions that i've definitely come across before, like that Cellulose vs enzyme question. They are definitely pulling those questions from the old study design and just tweeking it that tiny bit.

Btw, doesn't this study design continue until 2014?

I found it okay. Slightly different from the past exams though
Can anyone guess for me whether a 61/75 would yield me an A+ or not?
Hoping the A+ cutoff is low this year  :knuppel2:

I screwed up probably the easiest mark in the whole paper!!!

Forgot to add 36-38ATP for the cellular respiration question!  :tickedoff: :tickedoff: :tickedoff: :tickedoff: :tickedoff: :tickedoff:

That said, it was okay. A few questions threw me off at first (like why would Paul shampoo his hair?  :idiot2:

Definitely harder than 2006-2010, but think I did alright :)

PS are the answers up yet?

Oh I hope not :P

And they'll probably accept rRNA and DNA because rRNA makes up ribosomes....

Said something like that except I just said "it's a control in place of the independent variable (probiotic) so that results can be attributed to the effect of the probiotic" (or something like that) ... you think that would get the mark?

what the rna coming out of nucleus mRNA or tRNA and if i wrote tRNA and it was m but got the function of tRNA right do i get one mark

Personally I wrote mRNA as it copies the genetic code of DNA in the nucleus and looks like it was moving towards the ribosomes on the endoplasmic reticlum. You would need the function of mRNA to get the mark.

i thought there was going to be an expiremental design or rational design question! i would have done better if those were on it
and i left two questions out
omg fml  :'(

i wrote abscisic acid too for that random plant question and for siemese cat i chose A (is that right o.o)
i wrote mRNA for the digram question.
what did you guys right for the "the person has an infection if blablabla"  multiple choice question? i was indecisive about histamine released from cells or pathogen in intestines. at the end i chose pathogen one but now im thinking its wrong? :/

Definitely. I also think you'll get the mark for the aerobic respiration equation... and I'm 99% sure it's Ethylene that causes abscission, and I stupidly wrote abscissic acid. Not so sure about the rRNA instead of DNA though, let's hope for both our sakes they accept both!

Think it was the pathogen one... histamine could be a result of something else, not necessarily an infection.

And for the siamese cat one I think it was D (my teacher agrees) because all the other results contradicted the information...

EDIT: They might have to accept both ethylene and abscisic acid. Quick google, some say ethylene and some say abscisic acid... ???

These chemicals, primarily ethylene and abscisic acid, make trees lose their leaves by severing the link between the leaf and the tree.

Siamese cat I had D as it seemed like the cat produced pigments when below 37 degrees so as its place outside its color would changed?

I wrote "Water", will that be right? since it's injected and has no effect whatsoever?
Seen one of these questions before somewhere, and it said water...

for siemese q. wasnt the cats colour whitish colour (light not dark), so why is A wrong?
o and plant hormone daigram multiple choice question... was it giberellens or increased production of ethylene?

Title: Re: How'd you go?
Post by: WhoTookMyUsername on June 14, 2011, 12:08:25 pm
yeah wrote abscissic acid

was tossing up for 5 minutes in reading time

i knew NOB said 'absiccsic acid does not cause a;bkj;ckafdj;dasjf'
but

i wasn't sure if ethylene did

and there was only 1 tiny line, and AA is definitely involved, if only indirectly

they might except both

Think they have to because the internet says both are involved.

And A was wrong because it said newborn kittens were born dark (so lots of pigment produced) and the temperature would have been around 38 degrees. This contradicts the informations given.

It was the one where the pathogen was found in the leg muscle
It couldn't have been the others because A. histamine doesn't necessarily mean an infection (c.f. pollen etc.)
B. Finding bacteria in the intestine doesnt mean it's infected - there's good bacteria that live in harmony with our body
I forgot what the other option was - probably because it was really stupid

nature of biol book seems to suggest that ABA plays a main part in dropping/abscission of leaves:
Quote
Fruit that is about to fall from a plant, and dormant buds, both contain high levels
of abscisic acid.
so sad that there was no experimental design q. =((((

Aw, that doesn't sound too good but having said that let's not exaggerate our mistakes and forget about the good things we've done. It was your first exam ever for you guys so it's expected that you might make some mistakes and misjudge the amount of time that you have. Still, I'm confident you would have done well and will have plenty to build on and learn from for unit 4.

Good to hear that you went well, and don't be too concerned about MC - at least you did really well on SA. You can lose quite a few marks and end up doing well.

Cheers mate, that'd be great! Thanks for doing that. We'll try and get it up before 6pm but otherwise that'll be a nice backup plan :)

The picture of the cat made me laugh, no write up of a experiment which sadden me quite a bit. :( However it was an alright exam, alot of questions involving immunity. Got the "what type of nucleic acid is in here" wrong for cholroplast wrote rRNA for some odd reason


Man I wrote rRna as well lawl. Are you sure it's wrong? There's ribosomes in chloroplasts!

also jane, not sure if you have to add 36-38 ATP for the mark.



Wow! That's a massive surprise that there was no experiment write up. Did they at least have something where they required you to analyse how well an experiment was set up, or something like that?


My biology teacher was right about no experimental design :D Which is quite logical, since students seemed to be mastering it, I don't think VCAA would see the need to test it again.

I think because poison ivy isn't an allergen... it is harmful, and allergens are usually harmless but the body just overreacts. I don't think the question asked if it was or wasn't though... ??? I didn't say one way or the other I just described the histamine-mast cell-IgE response.

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!

"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..

Terrible question, afaik, the light chain can be inside or outside. Direct quote from my immuno lecturer was "you can draw it either way"

Sorry but I have to prep for work now, can't finish them. Probably would have skipped some of the last question anyway. As demonstrated earlier in this thread, I'm not perfect, these may not be correct and certainly aren't written to a perfect VCE standard. Lex and scocliffe will publish their ConnectEd answers later, those should be much better than my rushed job

Quote
1
a
The protein has folded in such a way that has projected the hydrophilic groups outwards. This will expose them to the water surrounding the protein and will allow binding, which will allow solubility.
b
plants
c
Sally is correct. Enzymes are predominatly protein based and thus this macromolecule cannot be an enzyme. Cellulose is a polymer of saccharides (sugars), which are the repeating unit displayed.

2
a
Thymic function is likely to correlate to weight. A weight increase is likely to indicate increased activity. Increased fat amounts (with age) indicate decreased activity. Thymic function seems to decrease after puberty.
b
Antigen in tissue is taken up by macrophages and dendritic cells for presentation to the immune system in the lymph nodes. However, Paul has previously been exposed to the poison ivy and thus has memory cells circulating; these T cells activate and stimulate the inflammatory response. This causes macrophage activation and cytokine release, which explains the red patches and blisters. The spread is explained by antigen uptake into lymphatics and circulation, allowing movement throughout body.
c
To remove any trapped antigen
d
As referenced in b), Paul has an effector memory cell reservoir that will immediately respond to any future exposure to poison ivy. As such, he should take care to avoid contact by the covering of skin

3
plants

4
a
00000 (hydrophilic head)
||||| (hydrophobic tail)
|||||
00000
b
alpha helix
c
A placebo is the administration of any compound that will not/is not thought to affect the variable being measured
d
The babies from Group A had mothers who received probiotics. These probiotics stimulated the immune system via TLR ligation to produce antibodies transferred to the foetus (this continued after birth). This prevented the "hygiene hypothesis" from being fulfilled and allowed development of normal immune function.
e
any differences between TLRs in mice and humans
any differences between immune transfer
(any 2 OK)

5
a
endocytosis
b
macrophages take up the bacterium and expose it to reactive oxygen species, low pH, proteolytic enzymes etc. in the phagolysosome.
antibodies bind the cell surface and either neutralise the pathogen or recruit the complement cascade proteins
c
it degrades proteins
d
the enzyme will have a specificity for a particular conformation (ie Ab shape). This conformation needs to be mimicked by the drug to allow binding and inhibition

I think they will except either DNA or RNA if you explained what is going on.  As chloroplasts have their own DNA and ribosomes, they would require RNA transcripts as well to transcribe their genes.

I think they may have been getting at this, because they actually wanted you to explain in the next column.

i forgot that its connected with fruit ripening - i kept thinking it makes things flower and thought those leafy things were flowers    :idiot2:
worst
exam
ever.


ethylene is definitely correct. abscisic acid was thought to have caused abscission but we know now that it creates seed dormancy among other things. my notes say:
Abscisic acid: inhibits growth, creates seed dormancy (until overridden by gibberellins), closes stomata
Ethylene: ripens fruit, causes flowers to die, stimulates abscision
hope this helps :D

Post by: jane1234 on June 14, 2011, 05:50:29 pm

Because it breaks down proteins. In this question they were referring to the breakdown of antibodies (which are proteins).
Title: Re: How'd you go?
Post by: stonecold on June 14, 2011, 05:50:41 pm
why is the enzyme called 'protease'? :)

Proteases are enzymes which break down proteins.  Antigens/immunoglobulins are proteins.  Therefore, the protease breaks down the antibody, and the pathogen avoids being captured by the immune system.

We think that they may accept both but in most cases ethylene is responsible. There are some plants that also have AA involved.

Hmm most of my answers were similar to that, but from the way I write I probably lost at least 50 marks for terrible explanations.

My thoughts exactly. Hate it when you pretty much have the concept, but it's written in a way that's a bit ridiculous and for the most part illegible  haha

LOL no only if you apply for special consideration. It can also go towards mediating your school's overall sac marks.

glad i didn't lose marks on MC, makes a 70 + that much more realistic :)

though when i had 10 minutes at the end of the exam, i forgot to check that i inputted the MC all correctly into the sheet, and wondered about the ABA/Ethylene question ( to which i put ABA :( )

25/25 for mc, guessed the one about the fungus though :). total of 69-71 I think from self marking, but we're always easier on ourselves. I answered the one about the thymus completely wrong, i think i must have no read the question fully.
I also wasn't quite sure on the poison ivy, I wrote about histamine and IgE antibodies but failed to mention inflammation, so will lose 1-2 marks there I think.
Hoping for an A+.

As for the paper on a whole, I think the multiple choice was fairly straightforward, and easier than previous exams while the short answer wasn't as easy to tell what the examiners wanted you to write as previous ones.

August can't come fats enough...

If I was generous, I think I got about a 67, if I was mean I got about a 63. I think it will be my wording that lets me down, because I thought I knew mosts of the concepts involved... Just didn't explain it correctly. :|
Hope for an A+, even if it's a low one!
