b. No response.
c. Weaker response.
d. Same response as the first infection.

Answer 1

Upon re-exposure to a pathogen, a secondary adaptive immune response is generated, which is stronger and faster than the primary response. This immunological memory protects us from getting diseases repeatedly from the same pathogen.

Step-by-step explanation:

Upon re-exposure to the same pathogen, a secondary adaptive immune response is generated, which is stronger and faster than the primary response. This secondary response often eliminates the pathogen before it can cause significant tissue damage or any symptoms. It is the basis of immunological memory, which protects us from getting diseases repeatedly from the same pathogen.
