- The term "turbidity" in microbiology refers to: a cloudy appearance in broth, meaning microorganisms did grow a cloudy appearance in broth, meaning microorganisms did not grow a clear appearance in broth, meaning microorganisms did not grow the clump of cells at the top of a broth a clear appearance in broth, meaning microroganisms did growarrow_forwardWhat statement correctly explains why moist-heat is more effective than dry-heat for sterilization purposes? The microbe's molecules are resistant to alteration in the absence of water. Dry heat will always be a lower temperature than moist heat. Dry heat dehydrates the microbes, and dehydration is a method of preserving microbes. Water is a good conductor of heat.arrow_forwardOf what practical importance are air borne microorganisms to the laboratory workers?
