Which of these is considered non-living by most scientists? A. Bacteria B. Viruses

Explain why many scientists consider viruses to be non-living?

Viruses are not considered living organisms because theyGroup of answer choicesare ubiquitous in nature.are structurally very simple.cannot reproduce by themselves.typically associated with disease.can only be visualized using an electron microscope.

While viruses exhibit some characteristics of life, scientists agree that they are not living things. What evidence supports this claim?Select one:a.Viruses do not have any mitochondria for energy.b.Viruses cannot evolve.c.Viruses have a different type of respiration.d.Viruses cannot reproduce without a living cell.

Why are viruses considered to be non-living?They are too small to be seen under a light microscopeThey do not contain proteinsThey cannot replicate by themselvesThey do not have genetic material2Which of the following structures are never found in viruses?NucleusProtein coatCell membraneGenetic material3When some viruses infect a host cell, they replicate their DNA and protein coats. These are then assembled into new virus particles causing the host cell to burst. What is the name for this life cycle?PathogenicInfectiveLyticLysogenic4Which of the following statements about the lysogenic life cycle is not true?It is associated with the symptoms of infectionWhen the host cell divides the viral DNA is copiedEnvironmental or chemical triggers can cause the viral genetic material to enter the lytic cycleThe virus joins its DNA to that of its host

Why aren’t viruses considered living organisms?Multiple Choicebecause they do not replicatebecause they do not possess genetic materialbecause they are composed of only one cellbecause they lack the metabolic machinery to acquire and use nutrients
