The warming of the thermosphere (the upper level of the atmosphere) is caused by the photo absorption of high energy photons. One of the processes that occurs in the thermosphere is the photo ionization of N2(g). N2(g) + hν → N2+(g) + e− What is the maximum wavelength of a photon needed to ionize N2 if the ionization energy of N2 is 1495 kJ/mol? In what region of the electromagnetic spectrum does a photon of this energy belong?

Which part of a feedback mechanism is able to monitor the conditions outside of cells and usually uses nerve cells to relay this information to an intergrating center
