According to scientists, ocean waves could be a source of energy. devices are being designed to capture the energy from waves and supply electricity to coastal areas. a direct benefit of utilizing this technology to produce energy would be the * a. destruction of habitats near the devices. b. decreased use of nonrenewable resources c. release of gases needed for photosynthesis d. increased use of finite resources

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom

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?

Which direction does the energy flow in this energy pyramid ?
