"fixation" (usually turning into ammonia)
yes, it does pass because when the de oxygenated blood comes through the left atrium the through the valves then into the left ventricle and goes to the lungs the it gets oxygenated but the de oxygenated blood goes through the veins and the oxygenated blood goes through the arteries and the capillaries join the both back to the process when it goes to the lung it gets oxygenated and the it goes back into the right atrium after that through the other valves the into the right ventricle then it goes through a big pipe called the AYOTA that is the process of the heart.
No you cannot smoke before a PET scan because it will alter the results and it will be detecting in you system which may cause problems with the scanning process.
You would want to separate the metals before selling to a scrap dealer to get maximum amount of money. If you just turn in a car to be scrapped in Europe they just run the whole car through a giant grinder and separate the metals and plastic that way. In North America the process is similar but not so centralized.

send a beam of light through the air, measure the intensity before (Io) and after (I) it goes through. optical depth = -ln(I/Io).

Biogeochemical cycles are basically of two types: a) Gaseous cycles like carbon (as carbon dioxide), oxygen, nitrogen, etc. b) Sedimentary cycles like sulphur, phosphorus, etc. In gaseous cycles, the elements have a main reservoir in the gaseous phase, and the reservoir pool is the atmosphere or water. The biogenetic materials involved in circulation pass through a gaseous phase before completing the cycle. In sedimentary cycles, the elements main reservoir pool is lithosphere and the biogenetic materials involved in circulation are non-gaseous. The sedimentary cycles are usually very slow as the elements may get locked up in rocks and go out of circulation for long periods.

Nitrogen needs to be fixed before it is used by plants.
Nitrogen must be in the compound form before it is used by plants or animals
