What is passive immunity?

B) Immunity acquired through the production of antibodies by the recipient's immune system.
C) Temporary immunity acquired through the transfer of antibodies from one individual to another.
D) Permanent immunity acquired through vaccination.

Name one way to acquire passive immunity in animals.

A) Through vaccination.
B) Through exposure to pathogens in the environment.
C) Through the transfer of antibodies from mother to offspring.
D) Through the production of antibodies by the recipient's immune system.

Answer :

Final answer:

The correct option is not given. Passive immunity is temporary and involves receiving antibodies from another source, which provides immediate protection without creating immunological memory. It is often naturally acquired by offspring from their mothers via placental transfer or breast milk.

Explanation:

The correct option is not given. Passive immunity is a form of immunity in which an individual receives antibodies from another source, rather than producing them through their own immune system. This type of immunity is temporary and can provide immediate protection, but does not lead to long-term immunological memory. One of the most common ways for animals to acquire passive immunity is naturally, through the transfer of antibodies from mother to offspring, either through placental blood during pregnancy or breast milk after birth. In medical settings, passive immunity can also be conferred artificially through the injection of antibodies, such as immunoglobulins, which can offer immediate, short-term protection after exposure to a pathogen.
