A bacterial cell has been genetically modified to have a plasmid that contains a gene that codes for human growth hormone (HGH). Which of these statements correctly assesses what happens with the bacterial cell after transformation with the plasmid? You may select all that apply A) the original bacterial cell will produce HGH
B) the offspring of the transformed bacteria will produce high HGH
C) HGH can be isolated from bacterial cultures and used as a pharmaceutical
D) the bacteria will not be able to replicate the plasmid and cannot express the gene
E) the bacterial cell can replicate the plasmid but will be unable to transcribe and translate the gene

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
