Suppose that the figure below shows the concentration of antibodies for an antigen produced by Clostridium tetani,a bacterium that causes tetanus.What could trigger the increase in antibody production marked by the arrow?

Question

Quizplus · Accepted Answer

The increase in antibody production marked by the arrow is likely due to a second exposure to Clostridium tetani, which results in a secondary immune response. During a secondary immune response, the body is able to produce a faster and more effective response to the pathogen because memory cells from the previous exposure are already present. This leads to a quicker and more robust production of antibodies, which is likely what is causing the increase seen in the graph. The other options (A, B, and C) are not supported by the information given in the graph.
