Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms. Disadvantage: Disadvantage of dichotomous keys is that if a single wrong decision is made at any juncture, a wrong identification will result. Sometimes it becomes obvious that an error has been made, and you can retrace your steps until you get back on the right track, but this is not always the case

Answer:
The correct answer would be option C.
Explanation:
Cellular respiration is the st of the chemical reaction that uses glucose molecule and produces energy as ATP that is the energy currency of the cell. It includes three-stage glycolysis, Krebs cycle and electron transport cycle with an intermediate stage in between Krebs cycle and glycolysis that is oxidative carboxylation.
The energy produced by the cellular respiration is utilized in all type of cellular function including repair and renewal of cell and tissue by the cell division.
Thus, the correct answer is option C.
