Questions

1. Flattering because includes all colors of the spectrum. People look sick in flourescent light because skin looks paler because the light doesn't include all colors in the spectrum 2.Some sources are continuous because an energy sources when ignited release all colors of the visible spectrum. Some sources are a line spectra because they don't release all the wavelengths of the visible spectrum which intern then doesn't show all visible colors. 3. Different colors of LED lights are displayed by lowering energy levels of different types of elements 4

Examples of Bioluminescence Animals: fireflies, glow worms Plants: types of mushrooms (jack o'latern), honey Fish: angler fish, gulper eel, pineconefish []

Fireflies "light up" when a enzyme luciferase acts on luciferin with the presence of magnesium ions, ATP, and oxygen []

Anglerfish possess bioluminescence by having a light that hangs off their head that essentially attracts other organism life in the dark enviroment. When prey gets close to investigate the light the anglerfish eats them. Other animals in the ocean that use this same tactic include the cookiecutter shark and flashlight fish.

A scientific usage that has been discovered from bioluminescence is that with the usage of recombinant DNA scientist can make organisms that weren't bioluminesence into a bioluminesence organism. Example of this is when scientist extracted DNA from a firefly and injected it into E. coli to make it light up. []

Fluorescence: Electrons absorb high radiation energy and let it off as light energy Phosphorescence: Chemical reaction occers were excess of energy from reaction is given off as light energy.
