<h3>To round to a significant figure:</h3>
- look at the first non-zero digit if rounding to one significant figure.
- look at the digit after the first non-zero digit if rounding to two significant figures.
- draw a vertical line after the place value digit that is required.
- look at the next digit.
after the evolution of the first living cells, fermentation wasn't needed, because aerobic respiration was now doable, since there was more oxygen in the air now. also, as the temperature increases, it becomes more energy consuming to conduct fermentation over aerobic respiration.
Hope this helps :)

Answer:
The correct answer is - Mitochondria.
Explanation:
Cellular respiration is the process that produces energy in the form of ATP from converting sugars into carbon dioxide. Cellular respiration is the process that takes place in the mitochondria organelle of the cell.
Mitochondria is known for the production of ATP and therefore called the powerhouse of the cell or ATP producing factory. These ATPs are used as the cellular currency of energy that is used to produce cellular functions.
