Which of the following is a characteristic of a secondary immune response?

Which of the following is a characteristic of a secondary immune response?

Step 1: Understand what the immune response is. The immune system protects the body from infections.
Step 2: Learn about primary immune response. This is the first time the body encounters a pathogen, and it takes time to respond.
Step 3: Know what memory cells are. After the primary response, some immune cells become memory cells that remember the pathogen.
Step 4: Recognize the secondary immune response. This happens when the body encounters the same pathogen again.
Step 5: Identify the characteristics of the secondary immune response. It is faster because memory cells are already present, and it produces higher affinity antibodies, which are better at fighting the pathogen.
