Ok, I'll try to remmeber as much as i can. I never like to look at model answers or recheck my paper with someone. But this paper makes me feel the need to, IT WAS THAT BAD!!!

So, I'll write the head of every question and then we can think of its parts.
1)Chlorophyll
2) ........
3) Myeloma
4) ........
5) Succesion
6) Peatland
7) Tree called "rhododendron" (measurements and sampling technique)
8) Bears


I can't seem to remember question 2 and 4, I'm not even sure the ones i wrote above are in the right order. But i'm sure 2&4, one was on antibiotics and i can't place the other one. (oh!, i think it was about HIV)

Btw, if any of you guys is bothered that i'm checking the questions after the exam (i always hated this ) You can tell me so i can either stop or put a spoiler alert before i mention part of an answer.

There was another one about Antibiotics i think......having mentioned this, what did you put for the type of antibiotic used which caused the slow increase in levels of bacteria in stomach?

It was antibiotics secreated from the gut flora which killed the foreign bacteria that had possesed a risk of infection. ..
The gut flora secreated these antibiotics due to competition for space or nutrients

yeah right, but then you were asked what did the slow increase in bacteria on gut flora suggest about type of antibiotic used

Here i explained the differences between using a bacteriostatic and a bacteriocidal antibiotic and related it to the qs. Also i added just in case the thing about using a narrow or a broad spectrum antibiotic
