Cellular respiration is a chemical reaction in which living organisms take in oxygen and glucose (sugar) from the environment and are converted to carbon dioxide, water, and ATP (energy). These products are then later outputted to the external environment. This is an example of a: A. Open system
B. Closed system
C. Process plants cannot complete
D. Cool process organism go through

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?
