6 marker is probably limestone extraction and quarrying ....i think.
It could also be to state and evaluate advantages and disadvantages of a certain topic
if its anything like the bio paper is there even a point of revising anymore? Might as well become one of those alcoholic rats or drunk 15yr olds and wing it
Can someone explain the Miller-Urey? What are you exactly meant to say? Also, what is the difference between the mixture of gases in that experiment and the alternative 'primordial soup' theory?
The Miller-Urey experiment is evidence for the Primordial Soup Theory. The experiment stimulated a version of early earth with all the gases presumably present on early earth to test the Primordial Soup theory and see whether life could be created from gases present and a form of energy (lightning).
Miller and Urey sealed a mixture of water, ammonia, methane and hydrogen in a sterile flask. The mixture was heated to produce water vapour. Electric sparks were passed through the mixture of water vapour and gases, simulating lightning. After a week, amino acids, the building blocks for proteins, were found.
