Probably, but I put that its a healthier option and its more ethical because factory farming is cruel.

i put there is less tropic levels therefore it is more efficient would that get a mark

I don't think it will to be honest. I'd say between 45-46 at most but it wasn't as easy as C2 papers which tend to be that high but obviously it won't be particularly low.

Did you have to use comparative language for example 'whereas' 'however' or...would listing advantages and disadvantages of the artificial heart valve in continuous prose be enough to gain all 6 marks? I included 3 advantages and 3 disadvantages.

FOR THE MYCOPROTEIN QUESTION (1st question of blp3h) what reasons did people put for why mycoprotein may be better to use?

I found it a lot easier than B2!!!

You know the question that said, name two things that are found in the blood (something like that)
I put : platelets and amino acids?
Is that right? because a lot of people put platelets and plasma.

Also for the question that said what are effects of increase in global warming, i put
Ice caps melting and change in biodiversity
Is that right?? thanks! x

Also for the question about how oxygen got into the blood, would it be enough to put diffuses through the alveoli in the lungs?

I put that less CO2 is produced when compared to cattle farming and that it is more sustainable.

Also for the question about how oxygen got into the blood, would it be enough to put diffuses through the alveoli in the lungs?

Phew! I put something about increased volume and decreased pressure, my answer was so poorly explained though :/

Did you do the B3 paper, because I don't remember doing a question about oxygen entering the blood stream? Did I miss it!?

I think it was at the back of the paper do you remember doing the last page?
