To prove that a certain fruit (in this case, an orange) indeed contains a certain compound (in this case, vitamin C); then the vitamin C should be extracted and isolated from the orange and must be confirmed by molecular analysis. The extraction process involves using chemicals (i.e. 6% MPA), and procedures such as centrifugation and filtration. Then the extract is stored and subjected to high-performance liquid analysis (HPLC) to measure the vitamin C content.
Unicellular organisms perform all required functions in a single cell (uni = one).
Multicellular organisms have more than one cell (multi = many/multiple). They also need organ systems to function properly.
These waves are of a higher frequency than surface waves. The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
The discovery should be first published in a journal to be reviewed by other scientists to ensure that it is correct/repeatable. After this, the discovery would most probably be reported in scientific magazines and then in newspapers, important discoveries would probably be reported by newspaper quickly though which leaves the potential for a discovery to be untested and incorrect.
