... In this eassy I will point out these implication and the causes and disadvantages of deforestation and prove that it is wrong to cut down forests. Deforestation is the large-scale removal of forests. Why does deforestation occur? There are a many answers to that question but the main ones are: Ø For agricultural purposes eg space for building. (overpopulation) Trees are logged for the purpose of space. In this day and age the human race is multiplying and therefore we require more space to expand cites and build more houses. To do this world government cut down any forests in their way. Ø Industrial commercial purposes Big industries also contribute to ...

... while building up energy and strength. After they hit land they begin to lose speed and die off due to friction. In the Northern Hemisphere usually travel first in a northwestern direction and in the higher latitudes turn toward the northeast. In the Southern Hemisphere the usual path of a hurricane is first to the southwest and then turning toward the southeast. are characterized by strong winds and pouring rain. Thunderstorms and waterspouts appear in the storm's cloud system. All contain an eye. The eye of a hurricane is a low pressure, calm area in the middle of the storm. The air in the eye is sinking and this causes there to be no rain in this area ...



Extinct Animals Research: Woolly Mammoth

... since the Woolly Mammoth is only three meters high. The huge tusks would allow it to scavenge for its own food, so no special feedings would be necessary. Feedings would also be needed on a less frequent basis since the Woolly Mammoth, much like today's camels, keeps under its sloping back a thick layer of blubber as nutrition when food was not needed. The problem in keeping a creature such as the Woolly Mammoth in a zoo- like surrounding would be poachers. Due to the endangerment of such a magnificent species, poachers of pelts and ivory would most certainly be after it's huge tusks and thick furs, so it would be necessary to post guards around it' ...



Nuclear Energy

... used as fuel for the power. Most of this power is fueled by uranium isotopes. These isotopes are highly radioactive. The isotope catches the fast moving neutrons created by the splitting atoms, it repels the slower moving protons and electrons, then gathers the neutrons and pulls them inward. While all these atoms are flying about they smash together then split many of many times, this is when the reactor grabs and pulls in the frictional energy to be processed into electrical watts. This usually causes heat or thermal energy, this must be removed by some kind of a coolant. Most power plants use water or another type of liquid based formula. these coolants ...

... of profanity and other obscene gestures during the youth viewing hours. However, during the prime time viewing hours it’s a different story. The method the television stations use is a mere waste of time and money because a little symbol in the corner of the screen is not going to prevent a child from watching the program. The only way this method can work is if the parents/guardian is there to change the channel but let’s be realistic, how many parents/guardians actuarially have the time to monitor everything there children watch. So most children do end up viewing these programs anyway, and whether we like it or not,the truth of the matter is television educates ...



The Kangaroo

... most well known species average weight is 145 pounds and from nose to tip of the tail is 10 feet long. The tail alone is about 4 feet long. The kangaroo has a small head with large ears and a small mouth. The fur is soft and woolly and some can have stripes on them. The kangaroo's body is specially built for jumping. It has two long, powerful hind legs with four toes on each. The front legs are short and have five toes with claws. These paws are used to handle food. Most of it's weight it in the hind legs and tail. Kangaroos can jump across flat land up to thirty miles an hour. Even though it is quite timid, kangaroos can fight very hard. They use there paws ...



Acid Rain 10

... sulfur. What causes this is a variety of industrial processes, such as the production of iron and steel, utility factories, and crude oil processing. In iron and steel production, the smelting of metal sulfate ore produces pure metal. This causes the release of sulfur dioxide. Sulfur dioxide can also be emitted into the atmosphere ny natural disasters or means. This ten percent of all sulfur dioxide emission comes from volcanoes, sea spray, plankton, and rotting vegetation. The oxides of nitrogen are by-products of firing processes of extreme high temperatures, for example: automobiles, and utility plants; and in chemical industries, for example: fe ...



Down Syndrome 2

... but these do not affect individuals as frequently as non-disjunction. Mosaicism is a mixture of two cell types, leaving the individual with some normal chromosomes of 46, and some affected ones with 47. Translocation occurs when part of the twenty-first chromosome breaks off and attaches to another cell. The total number of chromosomes is 46, however the excess material from the twenty-first chromosome results in the affects of the syndrome. With translocation, most cases occur sporadically, with no bearing on maternal age. These two types of this syndrome are very rare, being responsible for only 6 or 7 percent of all cases. Children with Down ...

... that genetic engineering is a revolutionary brake through. With the use of gene technology it is possible to create a ‘perfect’ organism. Useful characteristics can be transferred from one species to another, this includes animals with plants and vice a versa. As a result it is possible to make foods with high resistance to whether, temperature, pesticides, etc. therefore crop quality and amount grown would increase. Another area of genetic technology involves inserting genes into plants to make them immune to common viruses, this could increase the crop production. If the crop production could be increased, food would become cheaper and easier to ...



Surface Tension

... on the liquid surface that the surface layers on the opposite sides of the line exert upon each other. The tendency of any liquid surface is to become as small as possible as a result of this tension, as in the case of mercury, which forms an almost round ball when a small quantity is placed on a horizontal surface. The near-perfect spherical shape of a soap bubble, which is the result of the distribution of tension on the thin film of soap, is another example of this force; surface tension alone can support a needle placed horizontally on a water surface. Surface tension depends mainly upon the forces attraction between the particles within the given liquid ...
