They may credit something to do with nutrients too. It's right, so I'm assuming marks could be picked up there too.

As long as it is clear which gene is recessive, and which is dominant, it should be fine.

To be honest, I can't remember who had diabetes, but as long as it asked why the doctor knew that person had diabetes, the answers should remain the same.

it was defo A that had diabetes because after that there was a question that said suggest on reason why person B does not have diabetes for sure :smile:

Probs wrong, but worth checking LOL and for 4c, I wrote that the enzymes are specific, therefore they wont digest because that is a different type of lipid, also probs wrong, but yhh thanks :biggrin:

your answer for 4b i think is wrong mate, i dont think shape of the membrane changes?? :confused:

and for 4c its unlikely its right, but it could be

it may be 'A' who had diabetes, but the second part of that question was definitely about why that person did have diabetes (someone else please confirm).

Haha I'm saying that judging on my friend's reactions/everyone's opinions on here after stalking these threads for a few hours :L

Personally I would say it wasn't difficult but there were just a few questions that threw me

Yes this was the question and I wrote because insulin would be produced which lowers the blood glucose level?

Yeah pretty much the same with me, some questions were hard and some weren't that bad.

I wrote about the fact that the body produced insulin instructed the liver to converted the glucose into glycogen and that's why the blood had lower levels of glucose?
