Listed following are several astronomical objects. rank these objects based on their diameter, from largest to smallest. (note that the neutron star and black hole in this example have the same mass to make your comparison easier, but we generally expect black holes to have greater masses than neutron stars.)

Which of the following processes within viral replication is the greatest source of genetic variation in rna virus populations? a) high mutation rate due to lack of proofreading of rna genome replication errors. b) transcription from the host cell rna polymerase introduces numerous mutations. c) capsid proteins from the host cell can replace the viral capsid. d) viral rna is translated by host cell ribosomes.
