Why must most antibiotics be given some time to take effect on a disease-causing population of bacteria?

a. most antibiotics are large molecules and, therefore, take a considerable amount of time to reach the location of the disease-causing population in the body.

b. most antibiotics do not work on existing bacteria, so one must wait until the original disease-causing cells die off. prokaryotes can live for several days.

c. all three answer choices are correct.

d. quick regeneration time of disease-causing bacteria cells allows antibiotic resistance to be transferred during the beginning of treatment. submit for grading save and finish later?

The correct answer is d. "Regeneration" means "forming new cells," and signifies that the disease-causing bacteria cells are multiplying. When there are more of these cells, there is a higher chance for antibiotic resistance (making it take longer for the antibiotics to work). Once there is a smaller concentration of these bacterial cells, the antibiotics become more effective.
