- Penicillin is an antibiotic that acts by inhibiting the formation of peptidoglycan cross-links in a cell wall. Based on what you know about the nature of viruses and bacteria, will penicillin effectively kill the rhinovirus or coronavirus? Please explain your reasonUse the diagrams to answer the following question. Diagram 1 Diagram 2 Students are debating about differences between viruses and cells. Which student's argument is MOST correct using evidence from the diagrams? O A. Diagram 1 represents a cell and Diagram 2 represents a virus because viruses have a protein capsid while cells have a lipid membrane. O B. Diagram 1 represents a virus and Diagram 2 represents a cell because viruses do not have nucleic acids but cells do. O C. Diagram 1 represents a cell and Diagram 2 represents a virus because a virus has nucleic acids and cells do not. O D. Diagram 1 represents a virus and Diagram 2 represents a cell because cells have ribosomes to make their own proteins and viruses do not.HIV virus is classified as double¬ stranded RNA (ds-RNA) virus and belongs to a group of viruses called reoviridae? a.

- Is there such a thing as a “good virus”? Explain why or why not. Considerboth bacteriophages and viruses of eukaryotic organisms.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.Some people feel that viruses are living organisms. Give an explanation as to why they cannot be considered living at this time.
- A patient presents at the clinic with an acute viral infection. Assays that analyze the viral life cycle classify the virus into Group V with a segmented genome.

Because it's carried by fruit bats across Asia but almost never spills over into humans. B. Because it's carried by cats across Asia and easily spills over into humans. C. Because it's carried by fruit bats across Asia and easily spills over into humans. D. Because it's carried by fruit bats across America but it's not even noticed by the American people.
