B1 Edexcel exam tomorrow.

Yep. That's right. I would expect the mark scheme to tell examiners to look out for the word 'Phototropism' too.

But I'm annoyed I put lichens as a negative pollution indicator by accident in the first six mark question.

Edit - My Science teacher found the paper difficult and said it was nasty. A handful of people got question one wrong too, as bacterium was the answer for the first question.

oh pooop why did I not write that... that's so obvious too -_-

Does anyone have a good answer for the last question about MRSA?

I have it too... help... I have been revising the carbon and nitrogen cycles specifically, but I am freaking out. Seriously.
(It's nice to know other people around the country have it too though. Pretty cool)

Firstly I explained what MRSA is.

Then I wrote about the key points in the graph.
- Less people with MRSA at the start of the graph (1995, I think) possibly due to the disease first being contracted by people meaning there would be less resistance for the disease meaning less of it will be passed on to others due to more of it dieng.
-Increase in MRSA (In some year, can't remember) possibly due to the disease being around for longer, meaning it has developed a higher resistance to more anti-biotics and therefore it has a higher chance of spreading to other humans as the resistant genes will be passed on to the new generation of MRSA, because there is a higher chance of survival.
- Decrease in MRSA due to better pharmaceutical products which are newer anti-biotics that the disease has never came across, which will mean more MRSA disease dies, and therefore less can be passed on to other humans.

But the test was nothing to do with what we revised

I put that the graph is slowly starting to curve which could mean they are becoming immune to the antiseptic... Obviously got it completely wrong

Ah yeah... they only started using the antiseptic from 2005 I think?

I thought it went quite well... I was surprised that drugs, the nervous system, the carbon cycle, and the nitrogen cycle didn't come up at all!

Please DO NOT get mixed up with anti-septic and anti-biotics.

Anti-septic works OUTSIDE of the body to prevent dieases
Anti-biotics work INSIDE of the body to fight bacteria already in the body.

Therefore MRSA is a disease that is treated by ANTI-BIOTICS.

Edit: I would believe no credit will be given for references to anti-septics as that is wrong. Not sure though seeing I am not an examiner, just a regular Year 10 that just sat the exam!

Nope... MRSA is resistant to antibiotics, that's why they started using antiseptics (I'm pretty sure that was the whole question)

MRSA is resistant to SOME anti-biotics. Hence why you must finish an entire course of anti-biotics to prevent resistance developing.

Quote from NHS Direct
"Treatment for an invasive MRSA infection will involve a course of antibiotic injections"

Quote from BBC Bitesize - Antibiotics
"MRSA is methicillin-resistant staphylococcus aureus. It is very dangerous because it is resistant to most antibiotics. It is important to avoid over-use of antibiotics, so we can slow down, or stop, the development of other strains of resistant bacteria."
