deep ocean The oceans cover 75% of the world’s surface and contain 97% of its water; 90% of the seas lie beyond the shallow continental margins‚ and most are deeper than 2km. With the advent of modern science we have been able to discover what some of the deep ocean is like but there is still a vast area that remains unexplored. One thing we do know is that life at these depths is dominated by animals‚ not plants

Without using electricity‚ there are many ways to illuminate a parking lot. First‚ I can decorate the ceilings and walls of the parking lot with glow sticks (light sticks). This method of producing light is called chemiluminescence. Chemiluminescence is the direct production of light as the result of a chemical reaction with little or no heat produced. The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices is hydrogen peroxide and phenol oxalate ester

All of the plants on Pandora are much larger‚ and have different abilities. At nighttime‚ there is much bioluminescence in the plant life and the atmosphere may be dark but because of this there is much light. There is a lesser gravitational pull on Pandora than that of earth‚ which allows the Na’vi to jump off cliffs and land safely simply by hanging on to the

The GloFish‚ a fluorescent red zebrafish sold as a novel pet‚ has become the first transgenic animal sold to U.S. consumers. Its sale has produced regulatory controversies‚ a lawsuit‚ and profits for its proponent‚ Yorktown Technologies (Austin‚ TX). With the market plan calling for sales in a widening number of countries‚ continuing controversy seems likely. A genetically modified glofish is a brand of genetically modified freshwater zebrafish. Scientists insert a fluorescent protein gene to the

4.5 DISCUSSION The bioluminescent bacteria grow well and produce good glowing in the SWC agar media compared to the LA agar media. In LA agar media‚ the production of light was very deem. It also took much time to solidify and the agar media was too soft and forms hole‚ therefore good streaking couldn’t be done. There might be error in the composition of the LA agar media ingredients. However‚ when SWC agar media used‚ there was good growth of bacteria and bright production of light. When comparing

Fireflies have organs below their abdomens dedicated to their conspicuous crepuscular use of bioluminescence‚ which is actually used to attract mates and communicate. These omnivorous beetles take in oxygen and‚ with the help of special cells‚ the oxygen mixes with an ingredient called luciferin to produce light with virtually no heat. Each species uses

dichlorofluroescein quencher had a time of 8.86s and phenolphthalein quencher had the shortest time of 8.26s. Introduction Chemiluminescence reactions release energy in the form of light. Living organisms possess the ability to emit light by bioluminescence which is associated with vision‚ defense‚ prey and mate attraction. Chemiluminescence is a reaction in which a molecule absorbs energy and an electron is excited to the lowest unoccupied molecular orbital‚ and retains its spin value. This singlet

From the research‚ it is clear that a big emphasis has been placed on the search for life and the characterization of geological Martian substances. To add to this‚ the purpose of this mission is to locate evidence of current of past life underground and to test the ability of Mars to sustain life. Using the research conducted in past‚ current‚ and future Mars missions‚ this mission proposes three questions about Mars that correlate to the Mars Exploration Program (MEP) science goals and guide the
