SQA Higher Human Biology (Paper 2) - 27th May 2025

Anyone have any guesses for the essay question this year?

my teacher is predicting respiration but i kinda hope its gonna be vaccines

Vaccines as in like what they’re made out of and clinical trials?

yepp but it has come up before so i'm not extremely hopeful

Yeahh I doubt it’d come up again but maybe? I feel like this years might be on unit two but I’m not sure

something to do with the cardiac cycle or Atherosclerosis would be great

How did you guys find the paper?? I’m actually kinda happy with it

i enjoyed it!

For the 1-26 exons question, what did u guys write

Inversion and then I started talking about how a different order of exons results in different amino acids being coded for so a non functional protein. But I’m not sure if it’s right 😭

For the 1-26 exons question, what did u guys write

I did inversion and the mature mRNA transcript is shorter and exons are in a different order so the protein will be shorter and have a different structure. what did you guys put for the myelination one?

How did you guys find the paper?? I’m actually kinda happy with it

Btw I don’t think there was any mention of a stop codon in the question so the mRNA transcript wouldn’t be shorter but idk
Also I liked the myelination one, just talked a lot about how myelin is produced (glial cells) and less myelin means less insulation on axon and slower speed of nerve impulse transmission which is why babies are more uncoordinated than adults etc. it was a decent question you could’ve said a lot about it imo

What essay question did everyone do and how did we feel about it? I had enough time so I did both, and I thought both were decent questions. I’m so glad they decided not to put so much problem solving in this paper
