The need for energy, gained by respiration and photosynthesis, is the driving force of the oxygen cycle. select the best answer from the choices provided t f

True

Explanation: Oxygen cycle is the process by which oxygen is released into the atmosphere by photosynthesis and is used by aerobic organisms while the carbon dioxide is released as a by product of respiration. This carbon dioxide is used in photosynthesis for production of glucose.

Hence, for oxygen to remain in the atmosphere, it has to circulate through various forms of nature and this circulation of oxygen is called as oxygen cycle.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
