13. Cellular respiration that occurs without oxygen is called anaerobic respiration
14. Both aerobic and anaerobio respiration play crucial roles for life on earth.
15. Electrons that have completed their trip through the electron transport chain combine with oxygen to form carbon dioxide.
16. Anaerobic respiration can result in the formation of lactio acid.
17. Scientists think that glycolysis evolved before the other stages of cellular respiration because the other stages need oxygen

Which best explains how this maneuver unblock a person's airway?

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?
