I did pretty much that. Showed that it would be 80% before and after using examples.

I also wrote a note saying that if the number of cases increases by a certain percentage and the mortality rate stays the same then the percentage of deaths also increases by that amount.

The answer to the question they asked is definitely 80%. Although the fact that it is two marks makes me think that they made a mistake and meant to ask a slightly different question. I remember in Unit 1 or 2 last year they had a multiple choice question which didn't have a correct answer, so this could be similar. If it is they just take the question out and would mark the paper out of 88.

wasnt it 8 percent?
Edit: just realised it wasnt and i changed it to 80 never mind :L

Sadly, your not the only one who put that, I did too, god knows what I was thinking, I just didn't know what else to put. :biggrin:

Fml !

Haha well I'm feeling a little better about that little blip then :tongue:

for the percentage mortalilty of disorder patients i did 0.8 X 0.15 lol
definitely think thats wrong but 80% increase of patients were admitted and it said between 10-20% of them died so kinda from stats i thought the percentage of people who died would be the 2 percentages multiplied together.

anyone else do this?? haha i dont think anyone did :/ dammit, i didnt know what else to do

I also wrote about the pupil being a hole
LOL!

i said that its a hole in the eye and that you see the retina but the retiina doesnt reflect light so its black

I didn't even multiply :/ I divided 10 by 80 and 20 by 80, put my answer as 12.5 to 25% :/

did anyone write that ... cant remember fluorine something was too big while glucuse could move through carrier proteins on the cell surface membrane by active transport? :/ also, why is it good that it's small lipids or droplets? i said it could be easily hydrolysed and broken down and not stored as fat but that's probs wrong :/

Completely blagged the fluorine/radioactive glucose question, had absolutely no clue about all that chemistry-based stuff

I wrote a similar thing for the lipid droplets, mentioning a larger surface to volume ratio so it can be broken down quicker :/

1. It said it got inside the cell then was trapped (edit: actually no, that's what I took it as lol), so I wrote loads about inability to go through glycolysis or the link reaction, don't know though.

2. Larger surface area when there are many, and therefore reactions occur at a faster rate (easier hydrolysis would be accepted as that I'd think).

i wrote that its in small droplets because if it was in 1 large mass it would release too much heat and causing organ failure and also cause enzymes to denature, is this right?

I pretty much copied and pasted the article into the answers.. did anyone else find they did this a lot..?

Also, for the mortality rates we weren't given any before figures so how could we figure it out?
I just put the same figures that were in the article which was 10% -20%

I did this too! look at everyone speaking about this makes me think I've messed up the paper so much!

There wasn't enough of the damn spec in the paper. ><

Do you know what I'm starting to think theres so many of us we could be right! (Maybe)

Theres logic in it somewhere, I mean... holes are dark... :ninja:

Loool isnt it! I mean we werent even taught about it absorbing light or whatever so maybe they just wanted us to use common sense haha
