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 will be option-B

Explanation:

Antibiotic is the antimicrobial substance which inhibits the growth of the bacteria by interfering with different process and destroying the cell wall.

If the same antibiotic is used for the same colony of bacteria then bacteria can respond by becoming resistance to the antibiotic and as a result of this, the antibiotic becomes ineffective for the bacteria.

Since bacteria live for only a few days, therefore, the disease-causing bacteria dies off after a few days. The antibiotic then acts on the susceptible bacteria and kill the bacteria.

Thus, Option-B is the correct answer.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
