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.
14.) Most naïve, immunocompetent T cells wait to encounter foreign antigens in
the central nervous system
the bone marrow.
secondary lymph tissues.
15.) Helper T (TH) cells recognize non-self antigens only when they are bound to a
major histocompatibility complex I (MHC-I) protein.
natural killer cell.
major histocompatibility complex II (MHC-II) protein.
11. Answer: Option
D is correct
Dendritic cells and macrophages are better phagocytes.
Opsonization = Tagging foreign particles for phagocytosis
12. Answer: Option
D is correct
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
Breast milk provides passive immunity to newly-born individuals.
i.e. antibodies are directly passed on to the child from the mother.
