Hey, yeah it was cool, but in my opinion i found paper 2 easier than paper 1.
What did you write for the last question in p2 ( Why would it be painful to move the elbow) ? :biggrin:

I put that the synovial fluid and capsule don't go all way round joint and bones can rub together= painnnn

i said that
the sperm may have used up some but not all of the oxygen yet (for respiration)

and that it was only a small amount of sperm so the rest of his sperm may have been fertile

I wrote there is no cartilage in the bones therefore slight movement causes friction between the joints therefore causing pain... which causes the joint difficult to move

vacuole, isn't it?
Isn't the vacuole a place where water and sugars are stored?

The vacuous of a plant cell contains cell sap. Cell sap is a watery mixture of water, mineral ions and sugars. I don't think the vavuole is made of glycogen. The midsized dark spots (the food stores) are.

The midsized dark spots (not the really small spots because they are mitochondria).

Yeah, me too.

I was a big fan of that question, I must say (cheers, Edexcel, I'll take 10 marks :wink:

. I did however cock up the very first question on food webs due to an inability to read and/or count, it seems...
