Homework Answers
I believe the correct answer to be:
2) Option B) Antibiotics.
As different antibiotics have different mecahnisms that interfere with the normal cellular functions to destroy them.
3) Option B) Amoxicillin targets peptidoglycan and Option C) E.coli is gram negative.
As being gram negative bacteria the layer of peptidoglycan is thin in E.coli whe compared to S. mutans which is why ecoli is less susceptible to the antibiotic.
