... are another common area for white sharks. In the summer the sharks move to the coasts of Oregon and occasionally the Gulf of Alaska, and in the fall, they turn south and move along the offshore islands. They are also found in great numbers in the Australian waters. The great white is a very agile killer that hunts mostly anything in the ocean. They are carnivorous and usually prey on sick or injured prey. Just one drop of blood can make the shark go into a feeding frenzy. It is not made to swim fast and its usual speed is fifteen miles per hour. It migrates south to warmer waters to give birth to six to nine pups. The only wa ...
... atmosphere which is composed of carbon dioxide, nitrogen, argon, water vapor and oxygen. Mars also has no magnetic field. " Because the atmosphere of mars is so thin, wind velocities up to several hundred Km per hour are required to raise the dust particles during a dust storm, and these fast- moving particles erode structures with a sand-blasting effect " (Grolier, 1992). Therefore, the surface is basically plain-like and covered with large craters. There are also some areas where the rock is " jumbled." The poles of Mars are iced over and the temperature is about 160 - 170 degrees K. Mars also has its share of volcanoes. Most of these volcanoes are shield volc ...
... choosing and used the new vectors to insert these genes into the DNA of living organisms. Genetic engineers believe they can improve the foods we eat by doing this. For example, tomatoes are sensitive to frost. This shortens their growing season. Fish, on the other hand, survive in very cold water. Scientists identified a particular gene which enables a flounder to resist cold and used the technology of genetic engineering to insert this 'anti-freeze' gene into a tomato. This makes it possible to extend the growing season of the tomato. The marketing of genetic engineering inspires visions of perfect health, long life, and miracle foods. The reality is that these cl ...
... Newton's Method. The reason it sometimes cannot be found is because when the function is equal to zero, there is no slope to the tangent line. As seen in experimentation's, it is important to select an initial guess close to the root because some functions have multiple roots. Failure to choose an initial value that is close to the root could result in finding a the wrong root or wasting a lot of time doing multiple iterations while getting close to the actual root. On some occasions, the program cannot find a root to an initial guess that is placed into the program. In some instances Mathmatica could not find the root to the function, like if it is a para ...
... is rolled across the floor. The floor surface resists the motion of the rubber ball surface. This resistance or friction will slow down the moving object and eventually bring it to a stop. Friction exists between any two surfaces that touch, slide, or roll on one another. Any change in an object’s speed is called acceleration. An increase in speed is called positive acceleration, while a decrease in speed is called negative acceleration, or deceleration. Acceleration can also mean a change in direction as well as in speed. A force is needed to change the direction of an object, so a change in force can also mean a change in direction as well as a change in ...
... one day be judged as crimes against humanity and nature, which leads to the question: What kind of world do you want to live in? Our ancient habit is to stumble backwards into the future. We feel that we as individuals make little difference, as if history and the future just happen at us. Obscure plans, which have guided people forward in the past, have now rendered themselves useless. There are no known maps to show pathways into the future. We’ll need to consider back to our hearts, common sense and basic human capabilities. We’ll need to consider the deep issues at stake and make deep choices about them. This idea of disaster is actually an aide ...
... in the 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became "Down's syndrome." In the 1970s, an American revision of scientific terms changed it simply to "Down syndrome," while it still is called "Down's" in Europe. In the first part of the twentieth century, there was much speculation of the cause of Down syndrome. The first people to speculate that it might be due to chromosomal abnormalities were Waardenberg and Bleyer in the 1930s. But it wasn't until 1959 that Jerome Lejeune and Patricia Jacobs, working independently, first determined the cause to be trisomy of the 21st chromosome. Cas ...
... of the importance of the wilderness and space in our culture and an attitude that it is limitless and therefore we needn't worry." These words suggest that we are willing to reap the rewards of our vast resources but we fail to see the harm that we are doing, and will continue to do if we do not stop these actions. Although his approach for explaining his beliefs changes, Suzuki's tone of great concern remains consistent throughout the essay. After his views are presented, Suzuki begins to tell us what we have done to our country and how we are destroying it. Present day Canadians are compared to native Canadians which successfully serves its purpose in illus ...
... more energy-using devices, the temperation to exploit land for human use without regard for consequences is great. Frequently, several forms of environmental change are responsible for the disappearance of species. For example, as tropical forests are cut down, primates have progressively smaller feeding and living spaces. They also become more accessible to hunters, who kill monkeys for food and trap many primates for sale as pets, research animals, and zoo specimens. Some animal species may move into human communities when their own are destroyed. Extermination of marauding monkeys, roaming tigers, or foraging deer is easy to justify by people whose livelihoo ...
... (A), guanine (G), thymine (T), and cytosine (C). The deoxyribose molecule occupies the center of the nucleotide, with the phosphate group on one side and a base on the other. The phosphate group of each nucleotide is also linked to the deoxyribose of the adjacent nucleotide in the chain. These linked deoxyribose-phosphate subunits form the side rails of the ladder. The bases face inward toward each other, forming the steps of the ladder. The nucleotides in one strand have a specific association with the corresponding nucleotides in the other strand. Because of the chemical affinity of the bases, nucleotides containing adenine are always paired with nucleoti ...
