The graph below shows the changes in the temperature of ice when it is heated from -20 °C to 100 °C. Heat curve for ice. The graph shows the changes in the temperature of ice when it is heated from negative 20 degrees Celsius to 100 degrees Celsius. The label for the x-axis reads 'Addition of heat over time.' The label for the y-axis reads 'Temperature (degrees Celsius).' There are labels on the graph (from 'A' to 'E') that designate significant events while applying heat to the ice. Portion AB has a slight incline while increasing the heat from negative 20 degrees to 5 degrees; portion BC stays at 5 degrees for a while; portion CD steadily increases in temperature from 5 degrees to 100 degrees over a significant period of time; portion DE stays at 100 degrees for a while. Based on the graph, which of these conclusions is correct? Matter is in the form of ice in portions AB and CD. Matter is in the form of ice in portions BC and DE. Change of state takes place in portions AB and CD. Change of state takes place in portions BC and DE.

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
