primary immune response
secondary immune response
innate immune response
this is a nonspecific response to a pathogen.
immune cells recognize a specific pathogen and mount a quick response.
immune memory cells are created after exposure to pathogen.

Explanation:

• Innate immune response: Nonspecific, first-line defense against pathogens.
• Primary immune response: First exposure to a specific pathogen, creates memory cells.
• Secondary immune response: Subsequent exposure, uses memory cells for quick specific response.

Answer:

innate immune response → This is a nonspecific response to a pathogen.
primary immune response → Immune memory cells are created after exposure to pathogen.
secondary immune response → Immune cells recognize a specific pathogen and mount a quick response.
