13 which of the following best describes protection from antigens due to passive immunity?
A: Immunization leads to the activation of B-cell protection.
B: After primary exposure to an antigens, memory T cells remain to respond to a secondary exposure.
C: A mother passes antibodies to her child through breastmilk d
: Exposure to virus leads to the production of antibodies that can bind to the virus.
Homework Answers
Ans 13 )
C
A mother passes antibodies to her child through breast milk .
Passive immunity is through the transfer of ready made antibodies .
When the mother passes the antibodies to her child through breast milk is best example of passive immunity against antigens .
Rest all are active immunity in which body defense mechanism acts to produce antibodies against antigen .
