DNA is the bio molecule that contains all of the organisms genes. when cell divides through mitosis, the daughter cells contains exact copies of DNA from both of its parents.
This question is incomplete as there are no graphs included to study. I think this question is referring to K-strategy and R-strategy survivorship curves. In R-strategy, many offspring are produced, but there is typically very low offspring survival as there is little or no post-birth investment from the parents. In K-strategy, few offspring are produced, but there is substantial post-birth investment by the parents into caring for the young. Therefore, the R-strategy species will tend to have the highest number of offspring.
Cowpox and Smallpox are very similar diseases. When cowpox is injected into the body in a form of a vaccine, a weakened germ cell of the disease enters the body. Since it is weakened, the body is able to easily fight it off by sending antibodies. After the antibodies kill off the germ cell, B memory cells hold the information of the threat, so if in the future, when the host contracts the virus/disease again, the body is able to counteract it faster than it did the first time around. So since Cowpox and Smallpox are very similar, when a person is first injected with the Cowpox vaccine, the B memory cell remembers information about Cowpox. Then when the host contracts Smallpox, the body sees Smallpox as the same thing as Cowpox, so the body can fight off Smallpox quickly, and thus preventing Smallpox.
