B. In any population of organismsthere is always a certain percentage of individuals with an innate resistance to certain diseases due to the production of natural antibodies. These organisms tend to have better reproductive success.
C. Modern antibodies attack disease causing bacteria by altering their genetic makeup, rearranging, or mutating individual chromosomes. When this happens , the bacteria are no longer able to resist the natural defenses of the organisms they attack.
D. Antibiotics used to treat the same disease over many years tend to become increasingly effective. This is due to the fact that the antibiotics are often destroyed by bacteria on the first application but build up a resistance to bacteria over time.
