What structure(s)can allow a bacterium to persist,often over extended periods of time,in extreme environments such as those lacking in nutrients,dehydrating,and freezing,or in very hot temperatures?
A)nucleoids
B)capsules or endospores
C)plasmids
D)peptidoglycan
E)fimbriae

Capsules or endospores are structures that allow bacteria to persist in extreme environments. Capsules protect the bacteria from desiccation and nutrient depletion, while endospores are dormant structures that can survive very hot or very cold temperatures and lack of nutrients for extended periods of time. Nucleoids, plasmids, peptidoglycan, and fimbriae do not specifically provide persistence in extreme environments.
