Cloning 7
... properties.
While the potential benefits of genetic engineering are considerable,
so may be the potential dangers. For example, the introduction of
cancer-causing genes into a common infectious organism, such as the
influenza virus, could be hazardous.
We have come to believe that all human beings are equal; but even more
firmly, we are taught to believe each one of us is unique. Is that
idea undercut by cloning? That is, if you can deliberately make any
number of copies of an individual, is each one special? How special
can clones feel, knowing they were replicated like smile buttons. "We
aren't just our genes, we're a wh ...

Pascals Triangle
... time. He made contributions to science, mathematics, and religious philosophy. Pascal was born on June 19, 1623 in Clermont-Ferrand of central France. His father was a highly placed civil official and everyone expected Pascal to follow in his footsteps.
But Pascal proved to be a child prodigy. At the age of twelve, he figured out the proposition of Euclidean geometry with no help. At the age of seventeen, he wrote an essay on conic sections which contained a theorum that was named after him.
Pascal also invented many things. He constructed the first digital calculating system for his father. He invented the syringe and the hydraulic press. He also establis ...

Linux Vs Nt
... by examining their features.
I have decided not to discuss cost because it goes without saying: Linux wins the price to performance ratio. What is more important to discuss is the initial hardware and software fees, and maintenance and reliability which often go hand in hand. According to Sunworld, the estimated minimal required hardware costs that would go with a Linux machine is $200. In an NT machine, the minimal hardware cost rose up to $1300. This is because NT requires at least a 486 Pentium with 16MB of RAM. Linux can run fine on a 386 computer with only 8MB of RAM.
What do the majority of users need a computer for? Mainly word processing and the use of ...

The Grasslands
... have just visited a collective farm in the Soviet Union, a Masai
village in Africa and Abilene, Kansas, which is located in the U.S. These three
places are part of the world’s mid-latitude grassland region. Grasslands are
usually found in the interior parts of most continents. The world’s grasslands
are vast areas covered with grass and leafy plants. They generally have a dry
climate, little vegetation, and most grasslands receive only about twenty to
thirty inches of rain each year, with most of it coming in the same season.
Some grasslands may even receive up to thirty to forty inches of rain a year!
For example, since the grasslands of the United States h ...

Ebola Virus
... have been infected. With all countries considered, the 3rd world and the reuse of needles are a common practice, due to lack of funds and supplies. Though recovered patients pose no serious threat, the virus is present up to 7 weeks after being treated. Vomit and diarrhea contain the infected blood and mucus so any contact with this, e.g. in poor drinking water can cause contraction of the virus. Luckily enough Ebola is not airborne and in some cases due to its self-limiting nature, it has been known to die out within a person before killing the host. In one case when a Swiss researcher found the Ebola Tai virus, she contracted it from a chimpanzee. This w ...

Endocrine Disruptors
... to support these claims of human and wildlife harm is largely from laboratory studies in which large doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associ ...

Ideal Gases Vs. Real Gases
... do not have any mass. Ideal gases
obtain no volume unlike real gases which obtain small volumes. Also, since
ideal gas particles excerpt no attractive forces, their collisions are elastic.
Real gases excerpt small attractive forces. The pressure of an ideal gas is
much greater than that of a real gas since its particles lack the attractive
forces which hold the particles back when they collide. Therefore, they collide
with less force. The differences between ideal gases and real gases can be
viewed most clearly when the pressure is high, the temperature is low, the gas
particles are large, and when the gas particles excerpt strong attractive forces. ...

Environmental Isuues
... become fatal problems in the near future.
Many Americans get sick everyday; this usually warrants a trip to the doctor’s office. The doctor will usually examine the patient and prescribe an antibiotic. Antibiotics are being used as a way to solve medical problems. The heavy use of antibiotics is causing a threat to the population. They are so widely used and are beginning to become a contaminant in the environment. When used so frequently, antibiotics are found in the sewers, septic tanks, and even receiving waters. With antibiotics being so abundant in these places, the microbes here are now becoming resistant. With all of the sterilization and sanita ...

Artificial Insemination
... of another woman. Eggs can now also be removed from a woman's ovaries and placed in her fallopian tubes along with spermatozoa, thus allowing for normal fertilization.
Many times anonomus donors are used. Donors can be matched by factors such as race, color of eyes, hair and other physical characteristics, and are screened for conditions such as AIDS, gonorrhea and other STDS. Even though freezing sperm doesn't seem to affect a pregnancy, it reduces the sperm's movement and influences the success rate of . About 75 to 85 percent of women inseminated with fresh donor semen will get pregnant--especially if the procedure is repeated over several months. Unfortuna ...

Global Warming 3 -
... the entire planet. We are destroying the ozone layer, which allows life to exist on the Earth’s surface. All of these activities are unfavorably altering the composition of the biosphere and the Earth’s heat balance. If we do not slow down our use of fossil fuels and stop destroying, the forests, the world could become hotter than it has been in the past million years. Average global temperatures have risen 1 degree Fahrenheit over the last century. If carbon dioxide and other greenhouse gases continue to spill into the atmosphere, global temperatures could rise five to 10 degrees by the middle of the next century.
The warning will be the greatest at th ...
