Answer 1

1a.

A.IMMUNITY:A condition of being able to resist a particular disease especially through preventing development of pathogenic microorganism or by counteracting the effects of its products.-MERRIAM WEBSTER.

B.ANTIGEN:Antigen are the substance mainly protein on the cell surface .All microorganisms also can be antigen.

C.Phagocytosis:Phagocytes and other neutrophills engulf the bacteria or other pathogen through a process called as phagocytosis.

D.Macrophage:Monocytes are a type of leukocyte,these monocytes differentiate into cell-eating macrophages.

E.Antibody:Humoral immunity is a mechanism of adaptive defenses that are mediated by antibodies secreated by the B lymphocytes.

F.Autoimmune:Autoimmune is condition in which your own body immunity will attacks own body cells.

G.Chemotaxis:Chemotaxis is a movement of motile organism or its part in a corresponding direction to a gradient of increasing or decreasing concentration of a particular substance.

1b.A: A general defending process of body against the invaders.This mechanism happen within hours of an antigen attack to the body.These includes barriers like skin,chemicals in blood etc.

1c.T and B lymphocytes: The cells which perform acquired immunity respons are white blood cells with two methods like antibody response and cell mediated response which is carried out by Band T lymphocytes.

1d.F:The acquired immunity create immunological response to a specific pathogen,and leads to an enhanced response or fast response to the antigen to the next encounter of that antigen.

1e.Chemotaxis plays an important role inthe inflammation,neutrophills also create chemokines which is responsible for the monocyte recruitement.
