The big news in Raccoon Springs is a planned expansion of a local mine. The mine operators
promise well-paying jobs, safe operations, and lots of tax money flowing into the community.
However, many residents are worried about the possibility of an accident that could release
toxic materials into local streams. Ms. Noriega's class is studying a devastating mine spill that
took place in Colorado in 2015. Over 3 million gallons of contaminated water flowed into the
Animas River. The students find a map of the spill in relation to major watersheds in the United
States.
Based on the map, communities in which watershed were most likely affected by the Gold
King Mine spill? ES
(1 Point)
Columbia River Watershed
Colorado River Watershed
Mississippi River Watershed
Missouri River Watershed

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?
