A. Desiccation: Desiccation means drying out or removing water from a material or cell; this term directly names the general process of moisture removal.

B. Flash freeze: Flash freezing freezes a sample rapidly to preserve it, which does not remove moisture (it converts water to ice).

C. Lyophilization: Lyophilization (freeze-drying) removes water by freezing the sample and then sublimating ice under vacuum; it is a specific dehydration technique but not the general term.

D. Pasteurization: Pasteurization uses mild heat to reduce microbial load but does not primarily refer to removal of moisture.

E. Sterilization: Sterilization denotes elimination of all viable organisms, not specifically the act of removing moisture.

A. Koch: Koch’s postulates are criteria for linking a microorganism to a disease and are unrelated to chemical carcinogenicity testing.

B. Ames: The Ames test uses bacteria to detect mutagenic potential of chemicals; because mutagens often correlate with carcinogens, the Ames test is widely used as a screen for carcinogenic potential.

C. Mutation: Mutation is a general term for DNA changes; while mutation assays detect genetic changes, the named specific screening test commonly used for carcinogenic potential is the Ames test.

D. Cancer: “Cancer test” is not a standard name for an assay used to screen chemicals for carcinogenic potential.

E. Iowa: Iowa is a proper noun (a U.S. state) and is not the name of a chemical carcinogenicity assay.
