What does the graph show?
the s and p waves travel the same distance through earth's crust in the same amount of time.
the p wave travels through earth's crust more quickly than the s wave travels.
it takes the p wave 18 minutes to travel 6,000 km through earth's crust.
it takes the s wave 11 minutes to travel 8,000 km through earth's crust.

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?
