Select the incorrect statement with respect to acquired immunity.

  1. Primary response is produced when our body encounters a pathogen for the first time.
  2. Anamnestic response is elicited on subsequent encounters with the same pathogen.
  3. Anamnestic response is due to memory of first encounter.
  4. Acquired immunity is non-specific type of defense present at the time of birth.

Answer

(4) Acquired immunity is non-specific type of defense present at the time of birth.

Solution

As per NCERT, acquired immunity is pathogen-specific and is characterised by memory; the first encounter with a pathogen produces a low-intensity primary response, and later encounters with the same pathogen produce a highly intensified secondary (anamnestic) response, because the body remembers the first encounter.

Innate immunity is the non-specific type of defence present at the time of birth.

Statement (4) is incorrect.

Answer: (4)
