b. coli bacteria reproduce in liquid media containing either glucose or galactose. This statement provides an example of how bacteria can use different molecules as sources of matter and energy through different metabolic pathways.
In this case, the bacteria are able to use either glucose or galactose as a source of energy and matter for reproduction. This demonstrates that different bacterial strains have the ability to utilize different molecules through various metabolic pathways, which allows them to survive and thrive in different environments.
Option a, "Rhizobia bacteria form close associations with the roots of bean plants," does not specifically mention metabolic pathways or the use of different molecules as sources of matter and energy. Option c, "The antibiotic rifampicin inhibits the growth of some bacterial strains but not of others," does not directly relate to the researcher's claim. Option d, "Some viruses that infect bacteria reproduce by either the lysogenic cycle or the lytic cycle," relates to viral reproduction rather than bacterial metabolism.
