Answer:
The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.
Explanation:
Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.
To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.
As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.
Explanation:
Primordial organisms did not require oxygen for respiration as is the case with most organisms case today. These organisms were and are still mainly anaerobic. They main form of cellular respiration is glycolysis that does not utilize oxygen. Since other organisms evolved from the primordial cells, it is deduced that the early atmosphere was not mainly composed of oxygen but mainly carbon dioxide.
In today’s aerobic cells oxygen is utilized in the Krebs cycle as a proton acceptor making cellular respiration even more efficient in the production of energy. Remember that, utlimately, organisms evolve to fit into their environment.

Answer: C
Explanation: I'm not one hundred percent sure I know the context of this question, but biodiversity in an ecosystem means there's a wide variety of organisms, and a hotspot I assume would be an area that has an unusual amount of diversity.
Some sort of underground view of plates shifting, which can cause mountains and volcanoes to form and cause earthquakes
