how did u guys go?
i thought it was very hard
what did you do for the mc questions about the siamese cats? :S
-
i thought it was ok :)
i think i said C for the cat one not really sure what the answer was..tho,
was the answer to one of the questions abstic acid cause people were telling me it may have been ethylene??!!!
Aslo what did you menttion in the question about cortasine and blood glucose?
-
Oh god, I wrote abscisic acid too... Damn it! Overall, I thought it was a really, really bad exam.
-
How is it ethylene though?
-
i wrote a for the cats because inside the womb it will be the temperature of a cat at 38 or somethign in which the white fur doesnt grow
-
same
their internal body temperature shouldnt change if they go inside or outside? should it?
-
ohhh hmmp i think i got the cat one wrong :( i rushed that one cause it said what there body temps where maintained between
-
ethlyene apparently does so, not absciisc acid..
http://www.biology-online.org/11/10_growth_and_plant_hormones.htm check it out under ethylene...
i wrote ethlylene but friends said it was abscisic acid!
-
this is what wiki says
Abscisic acid owes its names to its role in the abscission of plant leaves.
It (ethylene) acts at trace levels throughout the life of the plant by stimulating or regulating the ripening of fruit, the opening of flowers, and the abscission (or shedding) of leaves.
so i think it might be both
-
Hmm...my Biolnotes states that Abscisic acid causes abscission in leaves and fruits, while ethylene promotes abscission of flowers and leaves. :S
-
The heinemann textbook says the effect of ethylene is leaf and fruit drop in a table, but somewhere else it says abscisic acid has a role in the abscission of fruit.. But then again, heinemann's a piece of crap :|
Edit: Biozone also says abscisic acid induces fruit fall. I think abscisic acid should be correct..
-
I got D for the cat one. My bio teacher said D was right
-
It has only recently been discovered that absiccic acid does not infact cause the leaves to fall off. However, as it is published under the current study design that it DOES - VCAA HAS to accept the answer. Wikki and all other resources will cite that abscisic acid isn't involved. So relax :)

So there'd be two answers?

Yes, I think they'll have to. My teacher and an independent lecturer said they would - but they also laughed off the idea VCAA would ask the question after the recent discovery.

what did u guys say for the pituitary gland ande how it can be a receptor and an effector
-
The pituitary gland is a receptor because it recieves the stimulus from the hypothalmus and it is the effector because it produces the hormone ACTH.
-
i thought it was a receptor because it picks up on hormones travelling through the bloodstream and it was a effector because it released the hormone ACTH
-
i got no C for the second column :S anyone happened to have the same?
-
Hey guys wat do u rkn the A+ cut off is for this yr's bio exam? i rkn i screwed up :(
-
its definately not absciscic acid.. coz i remember my teacher telling me its the opposite :/
but yeah its ethylene coz it helps with ripening and abscission... but dont worry i worte bloddy cytokinin -.-
