Viruses are not considered living because they do not have all of the seven characteristics of living things. Which one of these characteristics do viruses have?

  • A.Growth
  • B.Movement
  • C.Nutrition
  • D.Reproduction

Answer: D

Correct answer: Reproduction

Of the seven characteristics of life, a virus shows only reproduction - and even that only inside a host cell, using the host’s machinery. It does not grow, move, feed, respire, excrete or respond to stimuli, which is why viruses sit on the border of the living and the non-living.
