However, many scientists arrive agree that things must arrive at cardinal characteristics of life to be considered alive. The characteristics of life are each(prenominal) living things are composed of cells; all organisms are organized at cellular and molecular levels, free energy use, and response to the environm ent, growth, reproduction, and adaptation. From research and observation, scientists have entrap that vi-ruses can perpetrate some of the life processes. They destine that viruses have organization, the exponent to re-produce, and adaptations. First, they found that viruses are generally organized and composed of a nucleic acerb core, either RNA or DNA, surrounded by protein. Next, they found that viruses could reproduce.

It does not reproduce by sexual or agamic production, but by injecting its ancestral material into the nucleus of a living cell. Finally, they found start that viruses have adaptations . They have the ability to mutate into diff! erent strains to disagree man-made drugs. So, my answer would be no. A virus can not invent more of itself, or multiply, without assistance from the contents of living cells. Viruses are obligatory intracellular parasites. Viruses are assembled from a number of components that have been produced by the hijacked host cell - once assembled they dont continue to grow. A virus also relies simply upon the host...
