A. To understand the nature of an experimental subject
Number 1 is true the second one is true the third is true number 4 is true and lastly number 5 is false I hope this helps you but I’m very confident!
If there was a sudden drop in temperature after the evolution of the
first living cells, the rate of fermentation would drop due to the
temperature. My prediction would have to include the data, which is on
the graph. The question does not include a temperature to base my
hypothesis on so I would have to conclude that if the temperature
suddenly dropped to 35ºC to -20ºC, that the initial cells would die, and
that the atmosphere and the evolution of cyanobacteria would change
drastically.
