Deficiencies In Development Of Cocaine Children
<view this essay>.... cause a great damage to their children during the developmental years; especially in the aspects of cognitive motor and social/ behavioral deficiencies.
Cognitive deficiencies are those that deal with an individual’s thinking and reasoning process. These abilities are seen in the beginning school years, not at birth, but are the subtle characteristics that only through the school environment can be recognized. In a class environment, the deficiencies of a cocaine child are often confused with those of a disruptive child. The underlying truth is: teachers are not able to cope with them on an individual basis and give them more attention.
An initial sign tha .....

Human Cloning
<view this essay>.... the embryo in a petri dish getting sperm and egg cells. Now humans have a protected coating that forms around the mass of cells that begin to form called the zona pellucida. They dissolve the zona pellucida with a solution and take the two to eight cells and separate them into other petri dishes. Am artificially produced zona pellucida is added so embryonic development can continue. Now you have exact copies of the same genetic makeup in two to eight separate petri dishes. Even though this process sounds simple enough it has never fully worked because of abnormalities that occur like if the embryo is developed by two sperm cells the chromosome count is wron .....

Future Psychology

Soon enough it could be goodbye to dangerous stress, tobacco, burgers, serial killings, muggings, and smog. Times change. Many of today’s accepted virtues might 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 rende .....

Alcoholism 4
<view this essay>.... Vodka, Whiskey, and other hard liquors, require a further process known as distillation. The active chemical ingredient in beer, wine, and other alcoholic beverages is ethyl alcohol. Ethyl alcohol is a potentially addictive drug and a depressant of the central nervous system (Kestler 6).
Alcohol acts as a sedative and as an anesthetic, reducing nerve transmissions and impulses to the central nervous system. This depresses mental, motor, and vital functions such as pulse rate, respiration, and blood pressure (Kestler 6). The body can absorb alcohol very quickly, approximately 20% goes directly into the blood stream from the stomach, the rest enters the b .....

Global Warming…Fact Or Fiction?
<view this essay>.... attempt to show how data reports from governmental agencies differ with their own collection of data.
Global warming is not something to be concerned with. The computer models that are used to predict climate change are unreliable as the programming data is skewed and so is the data being put into the model’s equations. This paper will hopefully shed new light on a hot topic with some cold science!

Cloning And Embryo Research
<view this essay>.... grew embryo cells of Welsh mountain sheep in the laboratory. During a relatively stable stage of the cell cycle, they transferred 244 of the nuclei to the stripped-down eggs of Scottish blackface ewes” (Adler Par. 8). These nuclei had a full set of chromosomes, so fertilizing the eggs was not necessary. They then gave the eggs an electric shock to “initiate development” (Adler Par. 9). This was done after years of endless research. There was extensive research done in the area of embryo stem cells. Scientists have used such mouse stem cells for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site .....
