Those organisms are referred to as Ice fish‚ and they are one of the unique organism that live in Southern Ocean around Antarctica and Southern South America‚ where water temperatures remain relatively stable. Hemoglobin is a protein within mammalian red blood cells that transports oxygen for delivery to tissues throughout the body. Having red blood cells‚ would make the

Places traditionally known by snow or cold weathers now report less amounts of snow and a rise in temperature for example‚ in the Chimborazo volcano‚ Ecuador‚ the snow of the glacier is retreating at a rate of 0.5 meters each year also Antarctica reported to have the warmest year in all history. Remember that most of the water for human consumption comes from the glaciers‚ when they melt over controlled conditions the water resulted from the melting goes to rivers. Moreover‚ if the melting

Continental drift is a theory stating that the Earth’s continents have been joined together and have moved away from each other at different times in the Earth’s history. The theory was first proposed by Alfred Wegener in 1912. Whilst his general idea of continental movement eventually became widely accepted‚ his explanation for the mechanism of the movement has been supplanted by the theory of plant tectonics. However there was a problem in accepting this idea originally because Wegener had no convincing

UFO conspiracy theorists have a difficult time explaining why world are so concerned about the public being aware of aliens and what the purpose of a cover-up would be (Radford). Furthermore‚ Neumayer UFO is another sighting that occurred in the Antarctica‚ which a video of the identifying object was videotaped and put on YouTube. Benjamin wrote that “if it was indeed a spacecraft instead of a balloon or some other mundane object‚ why would the government – which routinely accused of going to extraordinary

Depletion of the Ozone Layer * Function and location of the Ozone Layer The ozone layer is a portion of earth’s atmosphere that contains high levels of ozone. Ozone (O3) is a triatomic molecule consisting of three oxygen atoms. It is an allotrope of oxygen. Ozone is formed when oxygen molecules after absorbing ultra violet photon then converts a single O2 into two atomic oxygen radicals. The atomic radicals then combine with separate O2 molecules to create two O3 molecules. The main function

in Earth ’s ozone layer keeps getting bigger and bigger"(Beyond Discovery). The ozone is a protective layer that occurs naturally in the stratosphere‚ 6 to 28 miles in altitude. Each year‚ since the late 1970 ’s‚ much of the ozone layer above Antarctica has disappeared‚ creating what is popularly known as the "ozone hole." This hole now measures about 9 million square miles‚ nearly the size of North America. Less dramatic‚ but still significant‚ depletion of ozone levels has been recorded around
