Answer to Question 1

ANS: A
Yeast reproduces by budding. Bacteria reproduce either by binary fission or conjugation. Rickett-sia reproduces by binary fission.

Answer to Question 2

ANS: B
Immunosuppression is not a requirement for the transmission of an infectious disease. However, a pathogen source, mode of transmission, and susceptible host must be present. A susceptible host does not have to be immunosuppressed to be considered susceptible. The host could have had surgery, be intubated, or have an indwelling catheter to be susceptible.
