Question

Which type of adaptive immunity does the following statement describe? This type of immunity is acquired via injection of antibodies from an individual or host that has immunological memory to the specific pathogen or antigen.

1) artificially acquired active immunity
2) naturally acquired active immunity
3) naturally acquired passive immunity
4) artificially acquired passive immunity

Answer 1

Option 3). Naturally acquired passive immunity is the type of adaptive immunity described in the statement. It involves receiving antibodies from an individual with immunological memory to a specific pathogen or antigen.

Step-by-step explanation:

The type of adaptive immunity described in the statement is naturally acquired passive immunity. This type of immunity occurs when an individual receives antibodies from another individual or host who already has immunological memory to a specific pathogen or antigen. The antibodies provide immediate protection against the pathogen, but do not confer long-term immunity. Hence, Option 3) is the correct answer.
