AQA - A- level biology - paper 3 predictions

I think the heart will definitely come up because there’s been nothing in 1st or 2nd paper.
Have a feeling respiration will come up too.
What do you think the essay will be on?

I think the essay could be on water or biological molecules.

Have a feeling the essay could be on something to do with the blood? Makes sense since heart, kidneys, tissue fluid and haemoglobin haven't been on?? Dunno though, hope its not too bad

I think water came up in a specimen paper though so idk if they would put it on our paper. I hope dieases comes up

digestion

i think the essay may be on the importance of gradients (e.g. pressure gradients, water potential gradients etc. )

On the specimen paper one of them is the importance of movement in living organisms. I feel like that fits in because it has a lot to do with things that have not come up yet.

My predictions based on what hasnt come up:
- Respiration
- Heart, SAN and/or a graph
- Muscles!!
- Homeostasis
- Partial pressures/Hemoglobin
- Gene tech / Genetic fingerprinting
- Nitrogen cycle
- Digestion of lipids?

Essay:
No bloody clue xD. Could be anything really. If it helps the specimen questions were; importance of movement, importance of receptors, nucleotides and water.

Good luck guys! We can do this

So far the essays that came up are: nitrogen containing compound, diffusion, movement, receptors.

I also think heart can come up because it's a big part, also perhaps the nerves, e.g. Sympathetic and parasympathetic qs

although succession came up in paper 2, there's been nothing on stabilising/directional selection and all that ecology stuff to do with environments and selection pressures?
