B. lipopolysaccharide membrane, capsule, peptidoglycan, phospholipid membrane
C. capsule, lipopolysaccharide membrane, peptidoglycan, phospholipid membrane
D. phospholipid membrane, capsule, peptidoglycan, lipopolysaccharide membrane
In a bacterium that possesses antibiotic resistance and the potential to persist through very adverse conditions, such as freezing, drying, or high temperatures, DNA should be located within, or be part of, which structures?
A. plasmids, nucleoid, and endospore
B. fimbriae, nucleoid, and endospore
C. endospore, fimbriae, and plasmids
