D. Mitosis and Cytokinesis
The answer is; glycolysis
This process converts glucose molecule to pyruvate. It is an oxygen-independent pathway, unlike the Krebs cycle. Glycolysis occurs in the cell cytoplasm while the Krebs cycle (aerobic pathway) occurs in the mitochondria. In the presence of oxygen, the product of glycolysis, i.e pyruvate, is fed to the Krebs cycle. If oxygen is unavailable the pyruvate is converted to lactate.
Physical is something you can have/ hold and mental is something in ur head that you can't see or hold.
On the phase diagram, conditions of pressure and temperature, at which two phases coexist in equilibrium are separated by a line.
