Most ocean food chains depend on phytoplankton as primary producers. Where in the ocean do phytoplankton live? within about 200 meters of the ocean surface, because phytoplankton require light to survive within about 200 meters of the ocean shoreline, because phytoplankton depend on nutrients that wash into the water from land throughout all ocean waters, because phytoplankton can tolerate a wide range of temperature and light conditions attached to shells along the ocean floor, because phytoplankton cannot float

What is one benefit of a non renewable resource, such as natural gas? a. generates large amounts of electricity b. less expensive c. produces pollution d. will run out eventually

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?

Someone me with this: a mineral' is determined by its actomic structure.
