After the EXAM (feedback)

[susien7]

did it specify that there were non homologus, i got confused, i don't think i read the questions properly... coz i thought they were and then i was gonna say the thing about exchanging material could only happen thougth mutatitons, but then i read something about them being homologus, so i put some totally whack answer down

[chlloe]

I said a plasimid for the vector.

I was a bit unsure with the bomb question, I put for the 3 things to consider, what is a independant variable, what is the dependant variable and what is the control, and how this related back to the question. Took a random stab at this one, probably wrong though!

[chlloe]

i think ppl r just being padantic, it was a fairly easy exam in comparison to some trial exams.

I thought it was easy compared to the trial exams I did. I probably wont ace it, but I dont think I did badly! --- but we shall see. Im not taking it as a good thing that I thought it was easy!

That's the sort of direction I was getting at however I completely muddled my thoughts. I did put a control however. But yeah I think that's what they were looking for because while nuclear radiation etc. is not really part of the study design, you are expected to know the key skills including experimental design in both semesters.

man i had no clue what i was writing for that questions, i just said really random things, maybe ill scrape a one mark for that question

Thank-god. I read over notes from a lecture, the guy stressed that we needed to know the experimental design stuff. Hopefully its all right!

[NE2000]

Btw, for the question with relative amounts of DNA, do you think they would accept 2 --> 1 or should it just be 4 --> 2?

[bucket]

I think both will be acceptable.

[chlloe]

I did 4 ---> 2.

In relation to the 'n'.

Because at the start of mitosis, chromosomes are doubled = 4n
Then at the end of anaphase, they are halfed as they seperate = 2n.

Depends on how you interpret it. Maybe ratios will be fine, hard to tell!

I AM SO GLAD BIOLOGY IS OVER!!!

and i found the exam REALLY REALLY HARD, i think i would be lucky to get a C in it!!!!!!!!!!!
i didnt answer all the questions, i just had no idea! especially with the new zealand veterans one WHAT THE HELL??
so right now i dont even think ill get a study score over 30!!! i screwed that exam up!!!!!!!

MC was okay

Short answer was tough IMO.

Off to commit suicide now. Fkn Bio

What did people put for the last question??? i cant really even remember what it was... something about providing evidence to support 2 different explanations about hobbits origin or something like that. I've gone blank can anyone remember???

[susien7]

i would say the general response from people is that it was sorta hard, with the exception of the terribly smart, so i'd say standardisation will be of great benefit to us don't worry.. i'm sure you've done fine

[NE2000]

Yes, feeling of some relief, although I didn't mention water. Found this on what seems like a good source:

http://www.labs.agilent.com/botany/cacti_etc/html/evolution.html

"Since the major processes of fossilization
generally  require sedimentation of mineral materials over
vegetative/floral materials, you can realize very quickly that with
even a hypothetical [xerophytic] ancestor to the cacti (perhaps
Pereskia-like in appearance), the environmental factors that favor
fossil preservation (save for amber entombment) would have been an
unlikely combination  of cacti and ample water for sedimentation.
Thus the fossil record for cacti is poor, or in fact absent."

Although my response wasn't so comprehensive as that....

One of the theories was about the hobbits being humans that had a disease which resulted in stunted growth
