Answer:
b. Feedback response
Explanation:
Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.
Bacteria with no plasmid will ONLY grow in medium without ampicillin. This is because bacteria without any plasmid do not have the gene for ampicillin resistance (ampR). Therefore they can only survive and grow in medium without ampicillin.
Bacteria with nonrecombinant plasmid will grow in both media.According to the image, this type of bacteria has the gene for ampicillin resistance (ampR) in their plasmid. Therefore, they are not affected by the presence of ampicillin in their environment and they can grow in both media.
Bacteria with recombinant plasmid but no vgp gene will grow in both media. These bacteria also have the gene for ampicillin resistance in their plasmid, therefore they can survive and grow in both media.
Bacteria with recombinant plasmid with vgp gene will grow in both media. These bacteria, apart from having the vgp gene in their plasmid, they also have the gene for ampicillin resistance. The vgp gene does not affect the expression of the ampR gene, therefore these bacteria are also ampicillin resistant.
