I too think that will come up. I recon the 6 marker may be a comparison between crude oil and biofuels

Yeah hopefully, the way these papers have been going so far, it should be an easy question that everyone can do but possibly a lot of the harder 1 markers that ask things that only people who know the subject inside out know and the sort you can't guess at😪 x D

I think this exam will be more limestone-based than others. Six marker might be "Evaluate the use of limestone in building materials"

Would that be like explaining the uses of mortar cement and concrete do you think? x

For the Miller- Urey one they could maybe ask a question like:
What was the primordial soup theory or Describe the primordial soup theory.

Hate suggest questions - why can't they just stick with asking the content I've actually learnt?

Smh at you AQA.

Basically an experiment by these two guys (called Miller and Urey, funnily enough) to see if life could be formed in the conditions scientists think were present on earth billions of years ago.

This link might help:
http://www.bbc.co.uk/schools/gcsebit...hererev4.shtml

Are you sure you can't find anything online? I'm surprised there aren't lots of explanations online...
