Match It: Humans rely on the ocean for a wide variety of resources. However, many human activities impact ocean ecosystems. Although some of these impacts have positive consequences, many lead to negative consequences. Below is a list of human activities and a list of some consequences of those activities. Match each activity with the consequences it can cause. Keep in mind that human activities may have several consequences. This is due today if you can help please do.

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?
