Question

match the term to the proper definition or description. choices are only used once. methanogens, thermophiles, and halophiles are members of this group. choose for use in reducing microbial numbers on living tissues. choose can utilize completely inorganic chemicals for energy and growth. microbe whose size would likely be much less than 1 micrometer. microbe whose size would likely be greater than 20 micrometers. choose disinfectant heterotroph antiseptic e. coli bacterium archaea covid - 19 lithotroph protozoan

Explanation:

1. Methanogens, thermophiles, and halophiles are members of Archaea. Archaea are a distinct group of microorganisms with unique characteristics.
2. Microbes that can utilize completely inorganic chemicals for energy and growth are lithotrophs. They obtain energy from inorganic compounds.
3. A microbe whose size would be much less than 1 micrometer could be a virus like COVID - 19. Viruses are typically very small.
4. A microbe whose size would likely be greater than 20 micrometers could be a protozoan. Protozoa are generally larger than bacteria and viruses.
5. Antiseptics are used on living tissues to reduce microbial numbers.
6. Disinfectants are used on non - living surfaces to reduce microbial numbers. Heterotrophs are organisms that obtain carbon from organic compounds, which is not relevant to the above descriptions.

Answer:

1. Archaea
2. lithotroph
3. COVID - 19
4. protozoan
5. antiseptic
6. disinfectant
