- Evaluate how each of the following results of scientific studies regarding mutations of the SARS-COV2 viral genome may implicate how humans can live with the virus for generations to come. Results Implication Scientific analysis of SARS-COV2 viral genomes from different countries has revealed that the virus accumulates about 2 new mutations per month. Many of these mutations have occurred due to their many battles with the immune systems of their human hosts. The vast majority of mutations have little or no effect on how the virus behaves, but scientists are keeping a watchful eye on mutations of the critical region of the viral genome: the gene encoding the spike protein. Mutations that give the virus an evolutionary advantage should be more likely to turn up repeatedly in the virus’ family tree.arrow_forwardOne study used phylogenetic analysis to detect different strains of the virus and marine recruits to thoroughly clean all surfaces in their living quarters. What was the primary result of the study? The COVID-19 infection is shared through Breathed air Dishes and utensils Body fluids Toilets Food Door handlesarrow_forwardChoose the correct the correct answer Viral particicles contain both nucleic acid and protein and can replicate inside of a host cell. Technically, this constitutes a "self -replicating molecular assemblage" which is also one way to define life. Therefore, one can conclude that a. Viruses are not living because they don't breathe oxygen b.Viruses are living c.Viruses are not living because they cannot think d. Viruses are not living because this formationis a simple repetitive process without the ability to respond to the environmentarrow_forward
