I can certainly see how this is likely to be a science book. With the latest photographic technology scientists have photographed everything from star nebulas, space gases, to exoskeletons of creatures, flowers, sun flares, waves in motion, inside cells, etc. so yes absolutely!
Cation-exchange chromatography is used when the molecule of interest is positively charged, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. So, the amino acids with negative charge will elute the first. Glutamate, leucin, arginine is the order of elution because of their pI values ~3, ~6 ~10.
CO2 is returned to the atmosphere by all methods except photosynthesis.
Through photosynthesis, a plant actually takes CO2 from the atmosphere and produces oxygen in return.
