An animal uses its long sticky tongue to snag bugs out of the holes in trees. Over time the trees bark becomes thicker, making more difficult for the animals to reach the bugs. In order to reach the bugs, the animal stretches its tongue, eventually causing it to become longer. The organism
reaches the bugs, survives, and reproduces passing the long tongue trait onto its offspring

answer; both surfaces of the membrane are nonpermeable

ans.

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.'
