Hi guys, this is a thread for predicting and giving a model answer for potential five markers for tomorrows exam. I haven't ever seen asthma come up as a five marker out of all the lung diseases. What do you guys think?

Not sure, possibly! I think vaccination and immunity will be a big question!

I've seen a few immunity questions (phagocytosis, vaccines), cardiac cycle, how a specific circulatory disease can lead to death, comparing types of microscopes, and a few on types of transport (not sure if that's unit 2 though, mind is a little hazy), and ORS.

Teacher's been having us practice questions on TB and cholera as well, seems to think that'll be something that might come up.

What 5 marker came up?
Christ this is an old thread

It ended up being: "Describe and explain how cell fractionation and ultracentrifugation can be used to isolate mitochondria from a suspension of animal cells."

And: "Describe the principles and the limitations of using a transmission electron microscope to investigate cell structure."

The former was a bit of a curve ball, IIRC, but the latter was no biggie.

You can check the paper over yourself: it's listed on AQA's legacy Biology section under BIOL 1 June 2015.

Please read the thread before commenting, it'd save us both time.

I already stated above that it was the June 2015 AQA Biology Unit 1 paper.
