... is today. The Internet is an easy to use technology that can do just about anything. But what people don’t understand is that the Internet is not all good. Much of the information posted on sites on the Internet is merely opinions, not factual information. When people look at this information, it looks and seems like trustful information, but most of the time, it is not. Although the Internet is a relatively new technology, television has been around for about fifty years. There are many problems with television though, mainly with the content of the shows. Many of the shows on television portray violence, drugs, sexual activity, and profanity. Peo ...

... the brain causing inflammation of brain cells and surrounding measures. White blood cells invade the brain tissue as they try to fight off the infection. The brain tissue swells (cerebral edema) and can cause destruction of nerve cells, bleeding with in the brain (intracerebral hemorrhage), and brain damage. This can cause neurologic deficits such as parplysis, speech changes, increased intracranial pressure, respiratory failure, seizure disorders, and shock can occur. SIGNS AND SYMPTOMS Mild cases absent superficial reflexes Sudden fever *** exaggerated deep tendon reflexes Poor appetite opisthotnos Loss of energy ...

... geological time because of climate changes and the inability to adapt to survive competition and predation. Since the 1600's, however, the rate of extinction has accelerated rapidly because of human population growth and resource consumption (17). Today, most of the world's habitats are changing faster than most species can adapt to such changes through evolution, or natural selection. The current global extinction rate is estimated at about 20,000 species per year, exponentially greater than the background extinction rate (17). Many biologists believe that we are in the middle of the greatest mass extinction episode since the disappearance of the dinosaurs 65 m ...

... needs to be an active member of a community we notice the continuos alteration of what exactly defines a comfort a necessity and a luxury. Comfort by definition is a condition of pleasurable ease or well being. By that definition there are endless numbers of object that could serve as a comfort. Take public transportation for example. The thought of having the train that takes us into the city is a commonly know option. Not always have people been able to choose public transportation as a method of getting to and from. Dating as far back as 1889 when the first method of public transportation was developed in Massachusetts. Before this the thought of having a ...

... would spread through the populations of the plants or animals. Over time this would finally lead to a development of new species. This theory was explained in the book ‘The Origin of Species’, which describes his studies on the Galapagos Islands in the Pacific Ocean. He noticed that the species on the islands varied slightly from each island and were adapted to local conditions. The reaction to this theory was immediate. Biologists argued that Darwin could not prove his hypothesis. Other criticised his ideas of variation and how he could not prove how these variations came about or how they were passed on. This part of his theory was not answer ...

... The problems with fusion are the molecules of hydrogen that are supposed to be fused, electro-statically repel each other at a great force. The only way to create the conditions where the it is possible to force these atoms together and override their repulsion is through enormous heat, this method is called thermonuclear. Even though fusion reasearch still needs a lot of time, there has been some progress in discovering how we can use this. The two fusion reactions that are the most promising both involve the heavier isotopes of hydrogen: 1) deuterium (composed of one proton and one neutron) Deuterium occurs naturally as a minor constituent in all h ...

... in many areas. Information technology has encouraged the development of productivity, increased student involvement and enabled students to complete joint projects with students in other cities, states and even countries (Carey 26). Studies on students who have twenty four hour access to laptops have shown that students shown an increase in problem-solving and critical thing sills, enhanced learning in core academic subjects, produce higher quality work and have even provided more one-on one time between teachers and students (THE Journal 16). Technology is an integral component of learning. Being that students learn at different rates, technology can indivi ...

... divide as would a regular embryo. The embryo was then implanted in a third ewe who only a few months later gave birth to Dolly 1 . Upon news of this, many people began to question the possibility of not only creating genetically identical sheep, but humans as well. There has been much controversy on whether or not the cloning of humans as well as animals is ethical or even moral. Also there has been much discussion as to whether or not the benefits of cloning outweigh the dangers. WHAT ARE THE BENEFITS IN CLONING RESEARCH? There is no doubt that Dr. Wilmut's new discoveries have brought an uproar of excitement between not only the scientific community, but t ...

... the eight we have," he says. Dr. Willard is currently negotiating with an American company to develop prenatal diagnostic tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing fetal cells in vitro and examining them, over one or two months, to see if there are two copies of a particular chromosome, which is ...

... ores. Cadmium has a number of industrial applications, but it is used mostly in metal plating, pigments, batteries, and plastics. Cadmium in the Environment Small quantities of cadmium occur naturally in air, water, soil and food. For most people, food is the primary source of cadmium exposure, since food materials tend to take up and retain cadmium. For example, plants take up cadmium from soil; fish take up cadmium from water, and so on. It is introduced into the environment from mining and smelting operations. Other cadmium emissions are from fossil fuel use, fertilizer application, sewage sludge disposal or galvanized pie corrosion. The largest source of these ...
