... may lose consciousness due to asphyxia (oxygen deprivation). During the exchange of gases in the normal breathing process, the blood stream absorbs oxygen from air in the lungs, while carbon dioxide passes from the blood to the air. When you hold your breath, the exchange of gases slows, as "stale" air in the lungs is no longer replaced by "fresh" air. Oxygen is actually removed from the blood stream during the exchange of gases. depending on how completely oxygen is replaced by helium, you may lose consciousness quickly and without warning - you may literally pass out while still standing. The usual result is an uncontrolled fall that can cause serious i ...

... liberty and equality for all individuals (Pfordresher, 423). The Industrial Revolution was changing England from a rural society to a nation of factories (Fuller, 280). England changed from an agricultural society to an industrial society, and from home manufacturing to factory production. When Napoleon came into power, people became as violent and corrupt as their former rulers. This was known as the Reign of Terror. "England emerged from the eighteenth century a parliamentary state in which the monarchy was largely a figurehead," according to Pfordresher. (Pfordresher, 423). The Victorian Period was from 1832 until 1901. It marked the climax of England's rise ...

... sequence of cognitive deterioration is observed (Lezak, 1993). The mild stage begins with memory, attention, speed dependent activities, and abstract reasoning dysfunction. Also mild language impairments begin to surface. In the moderate stage, language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in t ...

... Within the field there are many correlates to biological (genetic) and social causes. The present paper seeks to explore current research through investigating the social and bio-genetic influence of ADHD on child intelligence. Testing and treatments of those with ADHD will also be discussed. In accordance with Dulcan et al. (1997) ADD, ADD-H, ADHD, although not identical, will be considered interchangeably due to similarity. Characteristics and Testing of ADHD Intelligence Even though ADHD occurs in people of every intelligence, a majority of children affected experience academic problems. These children may have specific learning disabilities, such as ...

... warming. Oceans have a great potential for heat storage, the top two or three meters hold as much heat as the entire atmosphere. This warmth is continuously redistributed by surface and convection currents. Without the ocean there would be no life on land. Most of Earth's living space, is ocean, about 97%. And also 97% of Earth's water is ocean. There is a greater variety of living creatures in the ocean than anywhere on land. Scientists say that (including microscopic creatures) there may be 10 to 100 million unnamed species on the ocean bed alone. And that it could take up to 5000 years to classify them. The sea is a very has a very important contribution to ...

... is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less closely bound to the nucleii, are free to move in response to an applied voltage or electric field. The fewer condu ...

... and dust. Major proofs of the snowball theory rest on various data. For one, of the observed gases and meteoric particles that are ejected to provide the coma and tails of comets, most of the gases are fragmentary molecules, or radicals, of the most common elements in space: hydrogen, carbon, nitrogen, and oxygen. The radicals, for example, of CH, NH, and OH may be broken away from the stable molecules CH4 (methane), NH3 (ammonia), and H2O (water), which may exist as ices or more complex, very cold compounds in the nucleus. Another fact in support of the snowball theory is that the best-observed comets move in orbits that deviate significantly from Newtonian grav ...

... two sections in which one is the section of "resource availability and waste", and the other "the continuity of life support systems pertinent to survival." Thus, the environmentalists believe that nuclear energy should not be used for various reasons. First of all, the waste product, i.e. plutonium, is extremely radioactive, which may cause the people who are working or living in or around the area of storage or use, to acquire leukemia and other cancers. They also show how billions of dollars are spent yearly on safety devices for a single reactor, and this still doesn't ensure the impossibility of a "melt down." Two examples were then given of Chernoby ...

... chemicals like mercury, arsenic, and aluminum. Some of these minerals are changed in to gases and others become tiny specks of ash. As these chemicals drift, they may change again. They may react with other chemicals in the air. When sulfur dioxide combines with water, the result is sulfuric acid. When nitrogen oxide gas combines with water, the result is also another acid. When the clouds releases rain or other precipitation, the acid goes with it. This is called acid rain. The level of acid is measured in pH levels. The pH scale begins at 0 and ends with 14. A reading lower than 7 is called acidic, and a reading higher than 7 is called basic. S ...

... that such inventions as human clones, which are genetically constructed humans, and other genetically created figures, are wrong and should be stopped (Epstein 5). Overwhelming textual evidence proves that genetic engineering is not beneficial to society. Accordingly, genetic engineering is unethical and therefore should be stopped. One reason why genetic engineering should cease is because genetic engineering disrupts society’s moral values and causes society to act out in destructive ways. An online survey done by Time Magazine in 1997, found that 11% of those who were interviewed believe that if clones are created in the future, the genetically crea ...
