Suppose that a time machine allows you to go back in time (and to travel to Australia), and you have collected rabbits and Myxoma from the years 1955 and 1980. Once you are back in the twenty-first century, you infect both sets of rabbits with both sets of Myxoma viruses. The most likely result will be (1) that the rabbits from 1955 injected with the 1955 virus will have a survival rate than rabbits from 1980 injected with the 1980 virus. survival rate than those same rabbits injected with the 1980 virus; and (2) that the rabbits from 1955 injected with the 1980 virus will have a O A. lower; lower O B. lower; higher C. higher; lower D. higher; higher E. the survival rates will be the same in experiments (1) and (2)

Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.
