Thats what im assuming as well, could be on + and - of extracting metals, but they are both similar
It could also be on polymers, limestone cycle or early atmosphere / miller urey experiment
Or maybe they'll be nice and throw in something really easy as the six marker such as subatomic particles and their relative charges and masses (just like the B1 - that was quite an easy 6 marker)

Good suggestions, but last years 6 marker was on the atmosphere so im not sure that will come up again.
The seeds of the plant are crushed and the water is removed by distillation, leaving vegetable oil seperate.
I think you're wrong. The oil you get from crushing the seeds is added to water and then evaporated. It is then condensed and seeing as oil is less dense than water as well as oil being unable to dissolve in water, 2 layers are made with the oil layer at top and the water layer at the bottom. This can separated just by carefully pouring out the oil.

Firstly why would you add the oil to water in first place? Im pretty sure the water is distilled and dont have to mention anything at all about denseness its not a big complicated process.
Why is cooking foods in oil better then cooking foods in water? (1 mark) Explain how emulsifiers work?(3 or 4 marks) Describe the Miller-Urey experiment(4 marks)
THe theory that the solution of amino acids (building blocks of life) led to development of molecules and organisms. This was caused by the reaction (with lightning) with the gases in the earths early atmosphere.
