a bacterial cell with which modification might be resistant to antibiotics such as methicillin?
○ the ability to contaminate surfaces in areas such as locker rooms
○ the ability to produce an enzyme that breaks down the antibiotic
○ the ability to cause skin infections such as pimples
○ the ability to produce toxins that kill the human host
○ the ability to spread through contact between people

Explanation:

Antibiotic resistance often occurs when bacteria produce enzymes (e.g., beta-lactamases for methicillin) that inactivate the antibiotic, rendering it ineffective. Other options relate to transmission, virulence, or infection type—not resistance mechanisms.

Answer:

B. the ability to produce an enzyme that breaks down the antibiotic
