22) biochemical analysis uses similarities in as evidence for evolutionary relationships. a) dna sequences b) bone structure c) cellular architecture d) homologous structures

The correct answer is A) DNA sequences.

Explanation:

Evolutionary relationship determine the closely related ancestors of a particular organism. So it can help in tracing the evolutionary information about that organism. Phylogenetic classification use evolutionary relationship to identify new species.

The evolutionary relationship is determined by using a method called DNA sequencing which checks the similarities between DNA sequences within two individuals. More the similarities between the DNA sequences more closely they are related to each other.

But in prokaryotes mostly 16s rRNA sequences are used to determine the evolutionary relationship because most of the sequences are conserved in 16s rRNA. Therefore the correct answer is A) DNA sequences.

the correct answer is 2 and 4
