Fish fins are the most distinctive features of a fish, composed of bony spines protruding from the body with skin covering them and joining them together, either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops. 1  In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure.
emission of electromagnetic radiation during the course of chemical reactions. Such radiation, whether ultraviolet, visible, or infrared, is most commonly generated by oxidation. The radiation can usually be ascribed to the transfer of the oxidation energy to a molecule that is itself not undergoing oxidation.
The term RedOx comes from the two processes that occur during a reaction: REDuction and OXidation. These reactions occur together, they cannot occur separately. Oxidation is the term given to the process of gain/addition of electrons from another compound, ion, or atom.Because the oxidizing substance removes electrons from another substance, which are then added to itself, the oxidizing substance becomes âreducedâ (more negative).eduction is the term given to the process of loss/removal of electrons, which are given to another compound, atom, or ion. Because the reducing substance gives electrons to another substance it becomes âoxidizedâ itself (more positive). And because it âdonatesâ electrons it is called an electron donor.
