select all that apply.

a. dna viruses are considered living, unlike rna viruses.
b. types i and ii of the baltimore system are used for classifying dna viruses only.
c. dna viruses have a very high mutation rate.
d. double-stranded dna viruses are more common than single-stranded dna viruses

Answer;

B. Types I and II of the Baltimore system are used for classifying DNA viruses only.

D. Double-stranded DNA viruses are more common than single-stranded DNA viruses

Explanation;The Baltimore classification is a virus classification system that groups viruses into families, depending on their type of genome, that is DNA, RNA, single-stranded (ss), double-stranded (ds), etc..) and their method of replication.Type I is composed of double-stranded DNA viruses and Type II has single-stranded DNA viruses. RNA viruses have much higher mutation rates compared to the DNA viruses, they have approximately one mutation per virus genome copy.
