A new virus has been determined to triple its population size every 5 hours. The virus is introduced to an environment that is regularly sanitized. The environment is sanitized with 95% effective Clorox every 24 hours.    Now imagine there is a strand of this virus that is resistant to the Clorox wiping. If 50 non-resistant bodies and 1 resistant virus body is introduced to the environment, how many hours until the resistant virus population surpasses the non-resistant virus population? (Give as a whole number)

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.
