lol, i know that- but thats just an example of the graph i chose..Err.. there's only supposed to be one peak.
i wrote about how the better understanding has led to better use of genetic therapy. i did two examples not sure if correct.
Cancer tumours- how scientists insert genes from virus's into the tumour so the body recognises it as 'foreign' and attacks it
and i also just did the standard cystic fibrosis example.
could the cancer one work? cos reli a tumour is a mutation lol</SPAN>
good to see some else thought this question was shit... i got out of the exam and realised i drew a nephron instead of the kidney, but hopefully should still scrape a few marks... rest was reasonably straightforwardThe exam was ok. The only tricky section for me was the 6 marker on the kidney (wtf). The 8 marker was a bit challenging but i hope to get some marks for it. i made a few mistakes which i had to cross out grrr ie enantiostasis. Why did i have to write a marine animal instead of a plant. Man i got to learn how to read. Communication was fairly easy
cross fingers for a band 6
My one pretty much looked like the one I made ages ago for my summaries with the addition of heart rate increasing:weren't we meant to? or what were we meant to do

Wrong section of forum buuud.what kind of atar should i expect with these raw marks:
(this is what i predict i will get as raw marks)
math ext: 50/83 ---- school ranking 6
math 2U : 105/120---- school ranking 8
Biology : 80/100---- school ranking 2
SOR 1U : 35/50---- school ranking 20
English standard: 78/105---- school ranking 20
software design and development: ---- school ranking 1
chemisty: ---- school ranking 10
anyone else do this?hey bio peeps!!
How flopping good does it feel to be done?!?!?! Woooo! [chemistry on monday then i am completely done!]
i just had a question on that feedback diagram - was it meant to be a generalised model of feedback, or a model of a specific feedback mechanism???
it was annoying, i was in there and wasn't sure whether they were wanting thermoregulation or just a summary of negative feedback.
So i kinda did a general model, and then put next to it the associated content relating to body temp (i.e. Receptors = skin/brain; control centre = hypothalamus; etc...)
what did you do?
i thought the same so i put mutation in the DNAI think crossing over just mixes alleles, not creating new ones. Mutation in the DNA however, creates new allels (e.g. albinism)
How'd everyone go?? I think it was a pretty straight forward exam.. besides some multiple choice questions that were tricky :/ My options on genetics had big questions... 5 marks, 6 marks, and 7 marks consecutively :O!
Question 14 about the punctuated equilibrium/convergent/divergent evolution.. what'd you guys put? My teacher said it could be divergent.. or punctuated. I put punctuated.
Also the question with the stomates opening.. it could be either b) or d).. if it was a eucalyptus tree it would be b) but i put d)
yeah, it's set out and worded slightly different to mine, but yeah.anyone else do this?
exact same as me bro, im glad there's two of usI'm not sure whether this is correct
i dont mean to undermine you but the processes of filtration, reabsorption and secretion occur in the nephron not in specific parts of the kidney. the nephrons are located mainly in the cortex and outer medulla and there are almost 800000-1 million nephrons in each kidney.
i put the cortex and described role of nephron, and put ureter and described excretion of urea in urine and put in the renal artery bringing in contaminated blood from the body for excretion
fingers crossed its right
gl to everyone
bugger!it was definately b, why would stomates open at night when there is no light to photosynthesise with? They open early morning, close midday and open at dawn to minimise the water loss during the hottest part of the day.
