Compare and contrast the traits of viruses and bacteria. Why do most scientists argue that a virus is not considered a living thing? Explain your answer in 3–5 sentences.(4 points)

Answer 1

Viruses and bacteria are both microorganisms, but they exhibit distinct traits. Bacteria are single-celled organisms that can live independently and reproduce on their own, possessing cellular structures, including a cell wall and metabolic machinery. Viruses, on the other hand, are much smaller and consist of genetic material (DNA or RNA) encased in a protein coat; they cannot reproduce or carry out metabolic processes without infecting a host cell. Most scientists argue that viruses are not considered living things because they lack the necessary components for metabolism and cannot replicate independently; they require a host cellular machinery to multiply, thus blurring the line between living and non-living entities.
