more antibodies are produced
antibodies are produced faster
the production of antibodies starts sooner
all of the above
Which statement correctly describes a difference between phagocytes and lymphocytes?
Phagocytes have a very large, round nucleus and lymphocytes have a lobed nucleus.
Phagocytes destroy bacteria and lymphocytes destroy viruses.
Phagocytes are non-specific and lymphocytes are specific.
Phagocytes produce antibodies and lymphocytes produce antigens.
What are antigens?
Chemicals that stimulate the production of antibodies.
Harmful bacteria that are contained in viruses.
Chemicals that destroy foreign material when it enters the body.
Harmful bacteria found in some foods.

Biological
Natural
Synthetic
How do vaccinations work?
They contain enzymes which digest the pathogen.
They contain memory cells which provide immunity.
They contain genetically engineered bacteria that destroy the pathogen.
They contain antigens which stimulate an immune response.
