2010 Biology Exam 1 Discussion

Updated my post up there and my hands felt decently warm?

[Russ]

Haha did you guys all have really cold hands compared to when you were doing practice exams ?
When someone uploads it, who took it from the room (which is allowed - gotta ask afterwards) then we can mark it.

Ah so this will happen? Awesome!

[matt123]

yeaaumm ... considering i had 6 questions to answer in about 10-15 mins . my hands died at the end

[crayolé]

I'm confident with the MC except for the one asking which one has the self receptor ? I guessed for C for that one but everyone said it was B?

What about the antibody question asking how blocking the receptor it would make a vaccine more effective? That was the one question i left out because I didnt know how it was increase the effectiveness :/

[matt123]

i made up gibberish and said the protein cant decide if its plasma or memory cell
so the vaccine will make the body work hard to release both

[crayolé]

And @kingpomba

Farrr mine was like this D:, i forgot about the peak ---> decline afterwards zzz


And my graph on the test was 10x shakier because i realised i had 5 minutes to go LOL
Seriously felt like i had parkinsons or something :L

Do u reckon they will make chemistry harder this year?

For the self receptor one, it was the one which had 2 proteins on the surface that fitted into each other.



For the blocking one, i wrote...well i just forgot what i wrote.. ill need more of the question to remember but i think it was like a semi-trick question, it sounded like one thing but you had to read it again then i was like oooh it meant this...

[stonecold]

Oh god, MC is turning into a disaster.  Especially if that one wasn't cell S.
-Bloody chose glycolipid instead of carbohydrate
-Chose the wrong launday enzyme, the one with the highest temp

That is like four marks lost.  Was it the cat or the negative control for that question?

[slothpomba]

I also chose glycolipid, carbohydrate wasnt there was it? I narrowed it down to glycolipid or something protein i think... maybe..i dont remember but it was like a retarded answer

The negative control was the saline solution, which wasnt an option, so if you circled if something was the negative control , it was wrong.

William keeps his cat is the correct answer, since he showed no positive response to the cat antigens in the test.

[stonecold]

If your correct kingpomba, then that is only two marks gone.  Yay.

I knew histamine was the positive control, not the negative.  People were trying to tell me otherwise.

Was it cell S for the receptor one kingpomba.  I completely didn't even think to do what you did...
Cell S was option B if that helps to remind you.

[crayolé]

Yeah i did glycolipid too. There wasnt anything else it could be i dont think? It had the same structure as a glycoprotein except it was attached to the lipid.

For that membrane with the porous thing, does that "regulate and take part in the movement of water molecules across the membrane"? I kind of guessed that one

And stonecold, everyone I've asked answered B for that one ;] except me LOL

[stonecold]

i just wrote for things that can't pass through the membrane...

what you did sounds right to me though.

[crayolé]

Yeah fucking lucky, my last practice exam i did last night had something about that same thing, i read it in reading time and was like ZING!

[slothpomba]

Dont remember the letters but it was sort of a block with a triangle cut out.. i think... anyway the important thing is that they fit together
