Answer:

Type II Hypersensitivity

Explanation:

Hypersensitivity reactions are exaggerated immune responses that are detrimental to the host and Type II Hypersensitivity is also known as antibody-mediated hypersensitivity.

This type of hypersensitivity reaction involves humoral immunity and it occurs when IgM or IgG antibodies bind to cell surface antigens which lead to complement activation or IgG/FcγR interaction.

Clinical manifestations of Type II hypersensitivity responses include trans- fusion reactions, hemolytic disease of the newborn, autoimmune reactions to cellular antigens or tissues and hyperacute rejection of transplanted tissue.

In the history of Earth and the evolution of cells, aerobic cells appeared first and anaerobic cells appeared later.
Andreas93 [3]

Answer:

False

Explanation:

Scientist believe that the primitive atmosphere lacked free oxygen. Oxygen is a highly reactive molecule that would have made difficult for complex macromolecules to appear and then create life.  Rocks from the precambrian period support this theory.

Anaerobic cells appeared first, then photosynthesis appeared filling the atmosphere with oxygen and the aerobic organism develop cellular respiration to obtain energy, a process more efficient than anaerobic respiration.
