guys what did u put as the multiple choice on page one/two where it was like what does fat digested turn into???
and like what was the answer supposed to be for the why did [insert longaf latin name] get extinct?

both six markers were amazing omg!!! and for the blood clots i talked how about how it forms a protein antigen and then antibodies can be made specific to that antigen and then i waffled about radioactive tracers and stuff !!! tissue culture and dna extraction were so beautiful thank you edexcel

The monoclonal antibodies was saying about how you could do it for platelets as they would travel to the blood clots

1x1x1 was for the first cube. It said to work out the volume for the third one which was 3x3x3

I think i got like 64 minimum but most likely high-mid 70s and maybe low 80s.For the dna question i talked about double helix structure talked about made from monomers called nucletiodes each nuckletiode has a sugar phosphate and base sugar and phosphate form backbone and base is connected to sugar with complimentary hydrogen bonds with weak pairings between the two.The for the fruit i like sasid it wass crushed then detergent and salt are added ethanol glass rod (i explained in more detail but i cba to write)
