Mitosis is a type of cell division in which single parent cell divides into two daughter cells with equal number of chromosomes as in the parent cell.
It occurs in somatic cells of the body for growth and repair of the tissue.
It maintains the chromosomal number between parent and daughter cells and it is the reason that it is also called as equational division.

A facultative anaerobe.
Explanation:
Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.
Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.
Aerobic respiration produces 32 molecules of ATP from one molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.
Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.
Avoid carcinogens (like smoking residues..etc), eat healthy and sleep well in order to maintain a strong immune system
