... better illustrate the Galapagos Islands to the common reader. Mellville assumes that the reader is unfamiliar with the Galapagos islands, or "Encantadas," as he chooses to refer to them as and paints a picture of the Galapagos Islands using everyday terms. An important part of Mellville's style is that the he never directly describes the islands. "Take five-and-twenty heaps of cinders dumped here and there in an outside city lot" is how Mellville's description of the Galapagos Islands begins. This reduces the Galapagos islands from a large, nearly inconceivable place to objects of which most any reader can create a mental picture. When Mellville describes the fl ...
... to recent discoveries of large reserves. At present, uranium is only being mined and separated from ore. However, a huge untapped source is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18 tons of sea water contains 4.6x10^9 tons of uranium. All the world's electricity usage, 650GWe could therefore be supplied by the uranium in sea water for 7 million years(Energy 25). This is a only a theoretical number because it is not possible to get all of the uranium out of our vast oceans. Also, it does not include the fact that in that many years, half of the uranium will no longer exist due to radioactive decay. So, at wo ...
... over-wintering eggs. Such eggs are usually enclosed in a purselike ephippium that rests in the sediment at the bottom of the lake or pond until spring at which time the eggs hatch. 1. Daphnia magna. Take a small culture dish to the instructor to receive a few living D. magna. This is a very large species, as go, and one that is easily cultured in the laboratory. Return to your bench and observe the animals using the dissecting microscope. Note the characteristic jerky swimming motion. The uneven appearance of this motion is a result of there being only one pair of locomotory appendages, or oars. Try to observe the movement of the second antennae, which are the l ...
... feared dinosaurs. The word Tyrannosaurus means “tyrant reptile”. Since the Tyrannosaurus Rex was a meat-eater, its teeth were shaped in zig-zag form which allowed it to cut through meat like a steak knife (Benton 161). It mainly relied on its strength when catching prey. Because it could not swim, many of its prey would run for shelter into water. Also, the Tyrannosaurus Rex was able to take big breaths due to lots of lung capacity, but it tired easily and could not put up much of a chase when its prey ran. (Monatersky 287). The Tyrannosaurus Rex was an exciting discovery. It was found during the Bone Wars, a period when Paleontology was very popula ...
... into orbit. Work on rockets for missiles and upper atmosphere research was so great after World War II that by 1954 the possibility of launching a satellite was no longer in serious doubt. In October 1954 the Committee for the International Geophysical Year (IGY), announced to other countries that they were considering launching small satellite vehicles for space exploration. In April and again in July 1955 the USSR and the U.S. announced plans to launch for the IGY. The USSR launched SPUTNIK 1 on Oct. 4, 1957, and the United States launched EXPLORER 1 on Jan. 31, 1958. These two provided a lot of information for further work on . Emphasis was first pl ...
... to hunt because the Goose can see the hunter well before the hunter ever sees the goose (Wormer). This eyesight is essential for flying though, a Canada Goose can see three quarters of a sphere without moving its head (Wormer). The Canada Goose also has an acute sense of hearing, it's ears are positioned on the side of it's head (Wormer). They have either no sense of smell or a very poor one, but this does not impede the goose in any way (Wormer). Although there is a large variation in size all subspecies of Canada Geese look the same physically (Wormer) The male and female Canada Goose look almost exactly the same except the female can usually be recognized ...
... petroleum products. The unfortunate and unavoidable by-product of these manufacturing processes is dioxin, one of the most toxic substances on the planet earth. Dioxins are also produced whenever chlorine containing substances, such as PVC, are burned. Life as we know it will change, if a Greenpeace campaign is successful. The powerful environmental group has mounted a well-organized campaign that has as its objective nothing less than a total, worldwide ban on chlorine. With the public health and billions of dollars at stake, the debate over chlorine has become one of the world's most contentious and controversial issues. "Is a chlorine-free future ...
... worst natural disaster ever to strike his country. Greatest loss of life however, occurred in Mexico where Gilbert hit twice, first of all traversing the Yucatan Peninsula and two days later making landfall some 150 km south of the border with the USA, finally dissipating near the city of Monterrey. During its most intense phase at the western end of the Caribbean Sea, Gilbert was estimated to have central pressure of 885mbar, and maximum sustained winds in its circulation over 150kt (knots) with highest gusts in excess of 175 kt. The central pressure outrivalled the 899 mbar of the Florida Keys hurricane of 1935. Gilbert, at that stage an un-named tropical depr ...
... must grow. Wherever rainforests are found, sandy red coloured soil can be found as well. This soil contains few nutrients, which is why attempting to grow any sort of crops would be futile. On top of this soil is a thin layer of humus, which simply said is the compost made from the millions of dead animals and plants of the forest. When things such as leaves and animals die their remains are quickly broken down by a limitless amount of tiny organisms. Some insects that do just this sort of thing include: beetles, ants, termites and a host of others. With all of this death happening so quickly you would expect a sort of rotten smell to be in the air. This, ho ...
... water to be physically and chemically treated. CFCs were banned in '78 and a nation-wide toxic waste site cleanup program was developed in 1980. The EPA then evacuated Times Beach, Montana for dangerous levels of dioxin in soil, which was then criticized for its heavyhandedness and arrogance. Charges of mismanagement and undue political influence caused the head of the EPA to resign in '83. "The deputy director resigns because of charges of making a 'hit list' of employees to be hired, fired, or promoted because of political leanings. The former head of the toxic waste cleanup is found guilty of perjury and obstructing congressional inquiry. A regulation requir ...
