I put insulin is produced, and then went on to say basically what you have said, but mentioned the amount of mitochondria aswell
I done the same as you, I said insulin, and it contained many ribosomes for protein synthesis . Anyone else do this ?

And above, I was also confused on the cell division part, but I remembered that there was 2 divisions that take place , so it was C .

I would say I got about 30 marks overall I hope that's an A*. Probably isn't though.

The one about the man drinking the ice was very misleading!
Although when I thought about it, I realised. I'd already put Vasoconstriction, and then I had to say why this would help.

I put this means that the low core temperature will be further away from the skin surface, therefore allowing the surface temp to begin to match that of the 40 degree Celsius room.

what did people think of the vasoconstriction and vasodilation because when the body temperature lowers usually the blood vessels constrict. but in this question the surrounding temperatures were 40c higher than what he was so would the vessels dilate? CONFUSING QUESTION! and btw, glucose is c6h12o6 and starch is c6h10o5 they arnt the same thign should get both marks for that !

what did everyone write for that one-marker:
name a substance produced by the pancreas?
i wrote insulin?

and then it says how does the cell shown (C) adapt to produce this substance?
i wrote cus it contains lotsa ribosomes - protein synthesis, and also loadsa mitachondria for energy to make the insulin

please tell me thats right!!!!!!!!!!

I went on about how the body responded to the cold drink by warming up and so no sweat was produced by the sweat glands. (I then rambled on about how blood flow is constricted etc etc)

why would the blood vessels constrict if the outside temperatures were warmer than the normal body temperatures? surely when the core body temperature gets colder then they would dilate to take in more heat from the surroundings ???

carbohydrase converts maize starch into glucose, the glucose is used as energy source for yeast to respire anaerobically to produce ethanol from fermentation, the ethanol is then distilled to separate it from the remaining yeast and then it can be used as a fuel by itself or blended with petrol to produce gasohol

This is exactly what I thought, but they dilate to release heat do they not? Why would they do that if it was lowering the core temp? I totally agree though, the question was a biatch.

when the ice cold drink is drunk.... the body gets cold.. right?
so the body tries to WARM UP
so warming up:
blood vessels CONSTRICT
sweating REDUCED

What did everyone put for the "why do chromosomes come in pairs" thing? I was going to say one from each parent, but then I realised that it said that it applied "most organisms"...including ones produced asexually. So I said something about a double helix :p:
