.... step to understanding genetic engineering is to know the start of its creation. Genetics achieved its first foothold on the secrets of nature's evolutionary process, when an Austrian Monk named Gregor Mendel developed the basics of how genetics work. Using this, scientist studied the characteristics of organisms for the next one hundred years following Mendel's discoveries. These early studies concluded that each organism has two sets of character determinants, genes (Stableford 16). For instance, in regards to eye color, a child could receive one set of genes from his or .....

.... or are not perfect, then the formation of the crystal will be disturbed. One may ask him/herself, how is the formation disturbed if only one of the condition would happen to be modified? Most crystals are formed under water or under liquids with similar characters to water; and tend to form under liquids or solutions containing a maximum amount of solute. If the liquid absorbs additional solute, then the solution is supersaturated. If a tiny crystal, called a seed crystal, is added to the substance, a chain reaction would occur where the crystal growth will grow dramaticall .....

.... degree of harm and interfere with their normal development. The more the mother drinks the greater the risk of damage to the baby. "The Syndrome occurs in anywhere from point five to three live births per thousand in western countries…It is estimated that between thirty and forty percent of all woman who drink heavily during pregnancy will have a child afflicted with Fetal Alcohol Syndrome…Fetal Alcohol Syndrome outranks Down's Syndrome in prevalence and is the leading case of mental retardation" (Britanica 1). Once the damage is done it cannot be undone. Bab .....

.... all these services as a package in which a user can talk, exchange data, faxes and other documents at the same time, instead of having to use different networks for these services. 3. What is Satellite Communications? This is the use of orbiting satellites to relay microwave transmissions from earth stations to the satellite an to re-transmit those signals back down to another earth station by means of microwave transmission. Cellular Radio At present there are two types of cellular radio systems in operation in Ireland. These are: 1. TACS This system is an analogue s .....

.... “For we of the 20th century still treat the ocean as the endless, bottomless pit it was considered to be in medieval times.”(Heyerdahl) The majority of the world's population still lives under the misconception that the ocean is a hungry abyss, eager to devour all their waste. These beliefs, however, are all untrue. The average depth of the oceans is only a little more than a mile, when in fact, some lakes exceed this depth rather handily. Although the size of the ocean is often pondered, the thought that it may one day be gone, is never even considered. The vast major .....

.... a chain reaction. “It is often caused by new problems that worsen existing difficulties”(TWHSTSV 2). When one person sees another running about wildly and finds out what the cause is, he or she will do the same; until eventually the idea spreads to the entire population. Some problems that cause these are “overly strict regulations, lack of open communication between the authorities and the residents, as well as inadequate healthy recreational outlets”(Hayes 1). All these issues are things that if performed, can help prevent or calm an outbreak of m .....

.... Mendel’s pea plants proved there was a way of artificially creating trends in color of flowers. This discovery led to modern genetics. We now know chromosomes carry valuable information that determines characteristics in living species. When you put these two discoveries together you really understand how animals have evolved to their currant state. When animals are born the have traits that help them live or inhibit their ability to live. If the die they cannot mate with other animals therefore they don’t pass on the traits that killed them. The animals that l .....

.... The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. These chemicals have industrial halocarbons that break up into chlorine and bromine in the upper stratosphere when they react with the sun's rays. Chlorine e .....
