Answer to Question 1

ANS: C
Bactericides destroy only pathogenic bacteria. Fungicides kill fungi, and virucides kill viruses. Sterilization kills all microbes including spores, whereas pasteurization is a disinfection process that removes most pathogenic microorganisms except bacterial endospores.

Answer to Question 2

ANS: A
The shape of the organism does not make a difference in how disinfection and sterilization work. The number, location, and innate resistance of the microorganisms; the concentration and potency of the germicide; the duration of exposure; and the physical and chemical environment in which the germicide is used are all factors that affect disinfection and sterilization.
