It will be C because if a lower energy bonds are formed from breaking higher energy bonds then there will be excess energy to fuel other processes.
Answer:
The answer is: letter C, The cell took in another ancient prokaryotic cell, which began living inside it.
Explanation:
"Endosymbiotic Theory" states that<em> certain eukaryotic organelles evolved when multiple cells merged together.</em> So, this created a <em>"symbiotic relationship"</em> among them. The organism that lives inside the other organism is called the "endosymbiont."
An example of this are the eukaryotic cells, which took in a <em>prokaryotic cell</em> (such as the ancient chloroplasts and mitochondrion). These ancient prokaryotes used to be free-living. They were often engulfed by another cell. However, in this theory, they are not killed; rather, the host cell helps it to thrive. <u>This caused the organelles to evolve together with the host cell.</u>
Thus, this explains the answer.
Prokaryotic also has cell walls but besides that everything you have is correct
