.... usually not acidic. Because of differences in emissions and wind patterns, levels of acid deposition are generally lower in the western United States than in the eastern United States. This chart shows that not all fish, shellfish, or their food insects can tolerate the same amount of acid: Generally, the young of most species are more sensitive than adults. Frogs may tolerate relatively high levels of acidity, but if they eat insects like the mayfly, they may be affected because part of their food supply may disappear. As lakes and streams become more acidic, the numbers and types of fish and other aquatic plants and animals that live in these water .....

.... about 4000 human lives. Today, the use of other fossil fuels, nuclear power, and hydroelectricity instead of coal has greatly reduced the occurrence of industrial smog. However, the burning of fossil fuels like gasoline can create another atmospheric pollution problem known as photochemical smog. Photochemical smog is a condition that develops when primary pollutants (oxides of nitrogen and volatile organic compounds created from fossil fuel combustion) interact under the influence of sunlight to produce a mixture of hundreds of different and hazardous chemicals known as secondary pollutants. Development of photochemical smog is typically associated .....

.... and strong, sharp, curved toenails or talons. Owls are nocturnal for the most part and the others hunt during the day. Hawks evolved from raptors which also were birds of prey. Hawks evolved with eagles and falcons mainly but also with some other birds as well. Habitat and Biome Hawks live in all different habitats. Some in the foothills of the mountains while others live in the brushy open country and badlands of Oklahoma, Arizona, New Mexico, Nevada, and South-central California. Also in North and Central America for a more wide variety of hawks. Its biome would be in the Deciduous area as well as the Grassland and parts of the desert. .....

.... what it is. For many years electronic storage was very expensive. In the early days of computing a Megabyte or a million bytes of information could have cost up to $100,000 to store electronically. This same amount of information storage can now cost around ten cents. Because of this expensive storage limitation code written for these older computers was compressed in any way possible. One way to cut down the size of code was to compress dates to a format only six characters long. So instead of April 14 1999 the date would be compressed to 4/14/99. At the time of this programming this seemed to be the best solution to the space saving .....

.... and great, black talons. The distinctive white head and tail feathers appear only after the bird is 4 to 5 years old. Bald eagles are believed to live 30 years or longer in the wild, and even longer in captivity. They mate for life and build huge nests in the tops of large trees near rivers, lakes, marshes, or other wetland areas. Nests are often reused year after year. With additions to the nests made annually, some may reach 10 feet across and weigh as much as 2,000 pounds. Although bald eagles may range over great distances, they usually return to nest within 100 miles of where they were raised. Bald eagles normally lay two to three eggs once a .....

.... my ability tested my hypothesis. In conducting the tests I created graphs and tables of my work. At the conclusion of my experiment I came up with an answer that was almost unpredictable with the information that I was using. Although this was a crude experiment, I believe that I did gain a lot from it. Introduction The drug that I chose, Ibuprofen, is an anti-inflammatory analgesic. It is propionic acid that is white and powdery, and soluble in water, and organic solvents such as ethanol and acetone. (1) Its structural formula is: (CH3)2CHCH2 CH(CH3)COOH Its role of action as a drug is not completely cle .....

.... sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENSE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little top soil, there .....

.... of entirely new branch of mathematics, calculus, which has become an essential tool in most branches of physics. Therefore, I have come to state that physics is considered as “a body of knowledge and as the practice that makes and transmits it. The growth of physics has brought not only fundamental changes in ideas about the material world, but also, through technology based on laboratory discoveries, a transformation of society.� Uncertainty in Measurements Because the number of digits that are valid for any measurement is limited, the precision of all measuring devices is also limited. Every measurement is subject to uncertainty. Causes of .....

.... magnet field. If the distance between the coil and the magnet decreases; so the magnetic field, and therefore the flux, through the coil increases. The magnetic field of the magnet points upward. To oppose this upward increase, the field produced by the induced current must point downward. Thus Lenz's law tells us that the current must move by the use of the use of the right hand rule. If the flux decreases, so the induced current produces an upward magnetic field that is "trying" to maintain the status quo. Let us consider what would happen if Lenz's law were just the reverse. The induced current would produce a flux in the same direction a .....

.... 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 deforestation. EG "Macdonal .....
