Which among the following statement is incorrect with reference to immunity?
Answer & explanation
Correct answer: option 3
Innate immunity is non-specific type of defence, that is present at the
time of birth.When a host is exposed to antigens, which may be in the form of living
or dead microbes or other proteins, antibodies are produced in the host
body. This type of immunity is called active immunity. Active immunity
is slow and takes time to give its full effective response.When ready-made antibodies are directly given to protect
the body against foreign agents, it is called passive immunity. The foetus also receives some antibodies from their mother,
through the placenta during pregnancy. These are some examples of
passive immunity.
