Although flight evolved separately in bats and birds, their forelimbs are considered homologous. What does this information suggest about the relationship between bats and birds? A-While birds and bats do have a common ancestor, wings evolved separately in the two species.

B- The fact that birds and bats have the same bones in their wings shows that they must be closely related

C-Differences in the structures of the wings of birds and bats suggest that they do not have a common ancestor.

D-Wings in birds and bats provide little evidence for common ancestry but offer an explanation for a connection to winged dinosaurs.​

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
