The two major parts of Photosynthesis are the Calvin cycle and the light dependent reaction.
Some isotopes are radioactive, which makes them suitable for medical imaging procedures. Radioactive isotopes have found a wide range of use in medicine. For example, they are used as tracers for diagnostic as well as research on metabolic processes. They are also used in medical imaging procedures, these isotopes include fluorine-18, gallium-67 among many others.
"The density of a substance determines how much light is refracted"
