2010 Biology Exam 1 Discussion

[Milkshake]

I said three groups.  One on hard stuff, the other on soft stuff, and the last on nothing...ima lose a mark for that!

dude I wrote the same answer as you, I have never encountered a experimental design which didn't require a control group until the actual exam...

I was going to do a control group, but didn't know what to feed them :S. What did you give them to eat?

[stonecold]

I did so shit on this exam.  Fairly disappointed.

SA questions I am concerned about:
-Experimental design
-Treatment for the boy with mumps
-That Hex A transferase question
-3 mark question on the amino acid sequence.  I hope I wrote enough for 3 marks.

Say I lost a mark on each of those, and 3 multi choice questions, plus another 2-4 marks leeway.  Man that is like 10 marks.  Not good enough...

and yeah i didn't mention them being fed or something. i said constant factors for all other shit though.  like meals identital size, temp, water etc.

You mean measles? What did you write for that? What the IgM and IgE antibodies indicated or something. I wrote something really basic, 'Indicates that the child is currently fighting off the measles disease. Action that can be taken is administration of Interferon, to make unaffected cells more resistant to measles' :S

Nothing. Well my control had mice that were not given any pellets...
stonecold don't worry the whole state probably walked out of the bio exam feeling miserable, it was a really hard exam this year.
Anyone reckon next year will probably be easier? Seeing as the average will be quite low this year

That was the other questions where I couldnt find the other mark...

I just said the antibodies suggest that he has measles... then I said to treat the virus with a drug that inhibit its reproduction

for the action taken, i wrote about how they would isolate the child from others in his family who have no immune system and so have a 90% chance of getting the measles, like the info said above..... your answer sounds smarter.

I just said the antibodies suggest that he has measles... then I said to treat the virus with a drug that inhibit its reproduction

Now that I think about it that is probably right. I was wondering why there was no mention of rational drug design.
Damn I forgot he had antibodies against it already, I wrote that he should be given antibodies against the virus..... that's 2marks gone..

[stonecold]

I said not a lot could be done, but antiviral drugs could be administed, or inject more anitbodies to speed up recovery.  Also mentioned pplz in the house should be vaccinated.  

You remember the question in multi choice about the antigen, receptor for self, and receptor for non-self?  What was the answer, I misinterpreted it, but my answer may be right by luck.  I chose Option B: Cell S, if that stimulates you to remember...

I think it was one mark to recognise that he had an illness and one mark to treat it, you may have gotten one mark.

Stonecold:
antibodies dont speed up recovery so you might loose a mark there. Vaccination isnt very useful when he already has the virus.
That MC question you had to choose the antigen that didnt have a complementary pair that was also on its surface.

Oh crap I think I misinterpreted that boy with measles or whatever question. Bye bye marks

[stonecold]

Yeah, I know.  I just picked the one that was a receptor like a douche.  I'm guessing that wasn't the answer, which is okay, because it is a part of my 3 multi's that I fkd up.

Blue light or red light happy?

[The Detective]

Yeah your right, I don't know why I suggested a vaccine it doesn't even make sense.... and I had gotten all questions related to designer drugs correct on past exams...
Can't believe our results are given in august... I would feel better if we got it sooner so I could forget about it

[happyhappyland]

Yeah, I know.  I just picked the one that was a receptor like a douche.  I'm guessing that wasn't the answer, which is okay, because it is a part of my 3 multi's that I fkd up.

Blue light or red light happy?

I wrote red light. I went to my chem book after the exam and look at the UV light page, and blue light has higher absorbance probably blue light...

[Caspar]

Wasn't it one mark to indicate that he has disease, and another for vaccination of the family? That is what the prompting phrase about 90 percent of "vaccinated people living in the same house something something" seemed to be suggesting.

[Milkshake]

Yeah, I know.  I just picked the one that was a receptor like a douche.  I'm guessing that wasn't the answer, which is okay, because it is a part of my 3 multi's that I fkd up.

Blue light or red light happy?

Can't remember the actual letter for the cell, but it was the top left one shown. It had all different receptors, so that none of them complemented any of the others.

Won't the blue/red light depend on what colour the actual leaf is? I put red, googled and I think its blue...

EDIT: I actually did eenie meenie minie moe for that one . Was between blue and red. Only wavelengths I learnt about were red and far red, for germination of seeds =.=. As if they put that question on the exam
