11.) Antibodies can bind to and coat bacteria which stimulates cellular phagocytosis by ___________. This process is called _____________.

neutrophils and macrophages; cytolysis

mast cells and basophils; cytolysis

dendritic cells and eosinophils; opsonization

dendritic cells and macrophages; opsonization

basophils and macrophages; opsonization

12.) One characteristic of the adaptive immune response is specificity. This means that

the immune response is identical no matter how many times the antigen is presented .

the immune response is carried on by a specific group of cells of the immune system.

the immune response is more rapid and robust with each exposure to the antigen.

the immune response is directed against a particular pathogen.

the immune response starts in defined organs in the body.

13.) Newborns can acquire __________ immunity through breast milk.

innate

specific

active

passive

14.) Most naïve, immunocompetent T cells wait to encounter foreign antigens in

the central nervous system

the bone marrow.

the thymus.

the skin.

secondary lymph tissues.

15.) Helper T (TH) cells recognize non-self antigens only when they are bound to a

basophil.

major histocompatibility complex I (MHC-I) protein.

natural killer cell.

major histocompatibility complex II (MHC-II) protein.

hapten.

Answer #1

11. Answer: Option D is correct
Explanation:
Dendritic cells and macrophages are better phagocytes.
Opsonization = Tagging foreign particles for phagocytosis

12. Answer: Option D is correct
Explanation:
Specificity of the immune system: The immune system produces different antibodies for different epitopes
i.e. the response is specific for each antigen

13. Answer: Option D is correct
Explanation:
Breast milk provides passive immunity to newly-born individuals.
i.e. antibodies are directly passed on to the child from the mother.

Adaptive immunity has several features that distinguish it from innate immunity. Specificity in that each adaptive immune response is induced by a particular antigen, or surface feature that generates an antibody. An innate immune response might be stimulated by a PAMP, while an adaptive immune response is stimulated by a single feature of a bacteria. In addition, cells of adaptive immunity, B and T cells, are allowed to proliferate under certain conditions to mount a defense, this feature is clonality...
