The process by which a cell divides is called mitosis. It results in two daughter cells that are genetically identical to each other and to the original cell.
Multicellular organisms, depend on mitosis for growth and repair. Organisms repair some of their tissues using mitosis to regenerate new cells. Not all cells undergo mitosis at the same rate. In man, brain cells are much more difficult to regenerate than cheek cells which are constantly being replaced.
Topoisomerase is the enzyme that can be added to correct the untwisting that is led to strain ahead of the replication fork.

Answer:
c. Glycolysis evolved in an oxygen-rich environment.
Explanation:
Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.
Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.
