Multiple choice

What is the primary immune response?

  1. The first time the body encounters a pathogen and mounts an immune response

  2. The second time the body encounters a pathogen and mounts an immune response

  3. The process by which the body produces antibodies against a pathogen

  4. The process by which the body produces memory cells against a pathogen
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary immune response is the first time the body encounters a pathogen and mounts an immune response. This response is typically slower and less effective than the secondary immune response.

Multiple choice

What is the secondary immune response?

  1. The first time the body encounters a pathogen and mounts an immune response

  2. The second time the body encounters a pathogen and mounts an immune response

  3. The process by which the body produces antibodies against a pathogen

  4. The process by which the body produces memory cells against a pathogen
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The secondary immune response is the second time the body encounters a pathogen and mounts an immune response. This response is typically faster and more effective than the primary immune response.

Multiple choice

What are some examples of primary immune responses?

  1. The immune response to a new virus

  2. The immune response to a new bacteria

  3. The immune response to a new vaccine

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above are examples of primary immune responses. This is because the body has not yet had time to develop memory cells against the pathogen.

Multiple choice

What are some examples of secondary immune responses?

  1. The immune response to a second infection with the same virus

  2. The immune response to a second infection with the same bacteria

  3. The immune response to a booster vaccine

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above are examples of secondary immune responses. This is because the body has already developed memory cells against the pathogen.
