It may be reabsorbed by the presynaptic neuron and packaged again in the synaptic vesicles. 4. It may be (occassionaly) ...

... to high elevations, they're not thinking. First of all, water holds much less oxygen then the atmosphere, and it holds more when cold. Oxygen also diffuses slowly through bodies of water, so there's no clear depth distribution (it's higher right at the surface and around plants, but otherwise distribution ...
