Question

some biologists think that viruses should not be classified as living organisms because they a. do not make pigments. b. vary in the use of dna and rna in their genomes. c. infect all cellular forms of life. d. have an unusual cellular structure. e. depend on the ribosomes of other organisms in order to replicate.

Answer 1

Answer: E) depend on the ribosomes of other organisms in order to replicate

Explanation: Many scientists do not think that viruses are living because they cannot reproduce without the assistance of their host (need to infect cells and use their machinery to replicate). Many people see being able to replicate on your own, outside of a host, as one of the qualifications of "life", and viruses are unable to do just that.
