which one did you choose, the arrow heading to the right of to the left? i picked the enzyme heading to the right! because none of the theroxase (forgot the name) is being formed :tongue:

I don't remember that part - I know I said enzyme x because that would then prevent both of the products from forming, which would then also decrease the likelihood of a heart attack (that was the next part of the question).

What did you all get for that question where you choose X, Y or Z?

I wrote X because it prevents both of them being formed.

It didn't ask to explain anything so... and again AQA are confusing.

What did you all write for 8A? The question was something about vaccines preventing disease, explain how... I started to write about how a vaccine is an attenuated or inactive strain of a virus/bacterium/pathogen, then that the body has to produce its own antibodies by first, the primary, non-specific immune response (phagocytosis) and then the secondary immune response (humoral and cell-mediated) but I'm not sure if that's right or not...

:K:

if youre talking about the ORS

i literally stated what it contained
i.e. sodium, water, glucose, potassium, electrolytes
and why they were in it e.g potassium stimulates appetite and replaces lost ions

I didn't go into water potential or anything
could have easily written about that but I thought the question wasn't asking about that kind of thing :frown:

nope - for the heart rate I got the 85.7 part, then for the cardiac output I just x0.7 again to get 61.25 :/ I got the second part wrong though because everyone else got a big number like 10,750 or something...
