Question

In class, we discussed the numerous ways that a pathogen can evade a host's immune system. Which of the following below was NOT a method we discussed?

a. Different strains of the infecting pathogen.
b. Mutations of the infecting pathogen.
c. Gene rearrangements performed by the infecting pathogen.
d. Recombination events performed by the infecting pathogen.
e. All of the above were methods discussed.

Answer 1

The immune system evasion methods discussed, including antigenic variation, mutation, gene rearrangements, and genetic recombination, were all mentioned in the class materials provided, indicating that option e ('All of the above') is the correct answer.

Step-by-step explanation:

The question is inquiring which method of immune system evasion was not discussed as a mechanism used by pathogens in a biology class. The answer to this question is not directly provided in the excerpts, as they mention several mechanisms pathogens use, such as antigenic variation, mutation, gene rearrangements, and genetic recombination. Because all these aspects are indeed methods by which pathogens evade the immune system, as indicated in the text provided, the correct answer would be e.

All of the above were methods discussed.The immune system evasion methods discussed, including antigenic variation, mutation, gene rearrangements, and genetic recombination, were all mentioned in the class materials provided, indicating that option e ('All of the above') is the correct answer.
