Answer:

No atoms are created or destroyed in chemical reactions.

Explanation:

Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.

fgiga [73]
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.

Here is a similar table that just shows the metric units of measurement for mass, along with their size relative to 1 gram (the base unit).</span>
