increase oxygen availability.
increase the activity of normal flora.
prevent microbes from attaching and multiplying.
A microorganism able to grow both in the presence and absence of oxygen but shows better growth under anaerobic conditions is:
Microaerophile
Obligate aerobe
Obligate anaerobe
Facultative anaerobe

virus growth can be inhibited with antibiotics.
virus is a non-cellular particle made of genetic material.
Wearing a face mask interferes during the following stage of virus replication cycle.

The following statement is true about Lymphocyte T-cell in third line body defense mechanism.
Cytotoxic T-cells attack and kill antigens directly.
Helper T-cells stop the immune response once antigen has been destroyed.
Memory T-cells help enhance immune response by stimulating the B&T cells.
Suppressor T-cells remember the antigen in case the antigen attacks the body again.
The statement describes Immunoglobulin E (Ig E) in body defense mechanism.
First antibody is produced by the immune system.
Major action of this immunoglobulin is antimicrobial.
Immunoglobulin is produced in response to allergic reactions
Immunoglobulin attaches to microorganism & prevents mucosal surface invasion.
