what did u guys put for the greenhouse gasses 6 marker
no j in general. like amino acids make proteins and glucose is needed for aerobic respiration. that's what I said. I don't think you can talk about red or white blood cells for that question because they aren't transferred from human blood to the ticks. rather they are components within the blood.
I talked about glucose for respiration and water to provide a medium for metabolic reactions is that ok?
for the question where we had to draw the line graph, mine didn't start at 0. there was no line from 0-2 if you get what I mean - it started at 2 and then went down. is that fine?
bro they cut marks for extraploration or smthn... only start with data given....
btw the paper wasn't essentially bio.... it was outside the comfort zone you know.... like not the CHD or like organ type questions..... Wrote to like the last minute....
for that family pedigree question when it asked the genotypes of like the different letters, I wrote like homozygous recessive, or heterozygous dominant, etc, instead of writing out the actual letters do you think that fine?

and for the substances of the blood one i put minerals(iron) for the making of haemoglobin and calcium for the making of teeth and bones for Substance 1 and then for Substance 2 i talked about vitamins A for the retina in the eye and Vitamin C for cell lining surfaces is that correct? do you find that in the blood?

Yes vitamins are soluble so they are dissolved in the plasma I think
