You have two different bacterial species, E. coli and P. aeruginosa, each resistant to a different antibiotic. Your E. coli strain A is resistant to the antibiotic ampicillin, and your P. aeruginosa strain T is resistant to the antibiotic tetracycline. Strain A is killed in the presence of tetracycline, and strain T is killed in the presence of ampicillin. Interestingly, after you grow both strains together, each is then resistant to both antibiotics.

The presence of which of the following structures can explain this result?

i. Thylakoids
ii. Nanotubes
iii. Vesicles
iv. Flagella
v. Stalks

Answer :

Final answer:

Vesicles can explain the result of both E. coli and P. aeruginosa becoming resistant to both ampicillin and tetracycline after growing together.

Explanation:

The presence of vesicles can explain the result where both E. coli and P. aeruginosa become resistant to both ampicillin and tetracycline after growing together. Vesicles are small lipid membrane-bound structures that can transfer genetic material, including antibiotic resistance genes, between bacteria. It is possible that the vesicles transferred the resistance genes from one strain to the other, resulting in both strains being resistant to both antibiotics.
