False. I don't know how to explain it but they don't classify as living.
In geometry the base is the side or face of a geometric figure to which an altitude is drawn,
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.
An estuary is partly enclosed coastal body of water with one or more rivers flowing through it, and with a free connection to the open sea. it would be more of a collection. hope this help have a great day.
