Possibility Of Terraforming One Of Earth's Neighboring Planets
Number of Words: 1730 / Number of Pages: 7
... Mars and Venus.
Martyn J. Fogg authored what is regarded as a textbook of the future called Terraforming: Engineering Planetary Environments. I have chosen Fogg's book as my second primary source because it is the only book of its kind that addresses the question of terraforming in a non- science fiction context.
The successful terraformation of a planet requires the synthetic development of a biosphere. The problems that present themselves are indigenous to the Geophysical and chemical properties of each test subject (planet). Overcoming these obstacles requires an in depth knowledge of each plane ...

Endangered Species 2
Number of Words: 3779 / Number of Pages: 14
... between China's Ministry of Forestry and the country's zoos involved in panda breeding, as well as to an exchange of information and technology between Chinese and western scientists.
Some problems are, however, still experienced with animal husbandry, particularly the care and welfare of infants. Disease and rejection by the mother have been the main cause of death among cubs. Investigation of these, and other aspects of panda reproduction, now form an active part of the ongoing research programme.
THREATS
The main threats to the Giant Panda are habitat destruction and poaching. Young animals ...

Push/pull Theory
Number of Words: 906 / Number of Pages: 4
... forced out of some plants. Guttation only works when soil is almost completely saturated with water and leaves are not losing much water through evaporation. When the xylem is full of water, the molecules will not move back down the structure, but rather need to be expelled from the plant. They will move, by the process of osmosis, to an areas where there is the least amount of pressure. These areas are usually openings located on plant leaves. Once the water molecules reach the leaves, the excess water will be forced out of the plant by root pressure.
This push theory presents two major incon ...

Purple Loosestrife
Number of Words: 3067 / Number of Pages: 12
... new organism was introduced to a new habitat free from traditional
parasites, predators and competitors, purple loosestrife thrived in the
environmental conditions and by 1880 was rapidly spreading north and west
through the canal and marine routes. Purple loosestrife stands also increased
due to the importation of seeds and root stalks by horticulturists. It was
introduced to many communities as an herb, an ornamental garden flower and as a
desirable honey plant.
One of the earliest reported studies of purple loosestrife being a problem in
Canada was documented by Mr. Louis - Marie, in 1944. He s ...

Crude Operatons - Oil And The Environment

... year" (Gorman 48). To put this in perspective, that is approximately 4 football stadiums filled to the top with oil. That is just every year…and this has been going on for more than a decade. In total, 45 million tons of oil in the past ten years that have been put into the oceans. There are several ways that oil ends up in the oceans. One method is through drilling accidents and another is through spillage from tankers and other transports. In 1990 alone, 1/8 of the total oil discharged "…occurred daily in the New York - New Jersey Harbor" (American Oceans Campaign). And this is only an eig ...

Analytical Chemistry
Number of Words: 1120 / Number of Pages: 5
... identified chemical. Tests should
not use up excessive amounts of a material to be identified. Most chemical
methods of qualitative analysis require a very small amount of the sample.
Advance instrumental techniques often use less than one millionth of a gram. An
example of this is mass spectrometry.
Quantitative chemical analysis is used to determine the amounts of
constituents. Most work in analytical chemistry is quantitative. It is also
the most difficult. In principle the analysis is simple. One measures the
amount of sample. In practice, however, the analysis is often complicated by ...

Consciousness As Determined Through The Times
Number of Words: 1041 / Number of Pages: 4
... included an analysis of consciousness as a form of relationship or act of the mind toward objects in nature, and a view that consciousness was a continuous field or stream of essentially mental "sense data."
The method believed by most early writers in determining consciousness was introspection—looking within one’s own mind to discover the laws of it’s operation. This belief was limited when it was apparent when observationalists could not agree on observations. Obviously due to the differences in one’s own idea of introspection and the underlying views they possessed.
The failure of i ...

Cloning Of Animals
Number of Words: 508 / Number of Pages: 2
... sheep cells before
their success, but the task was perfected and accomplished. Now this
accomplishment has made it possible for the cloning of almost any mammal,
including humans.
To the average person, exactly how the technique works is unclear.
Scientist predicted that by making cells dormant and bringing them close to
death, something happens to break the chemical locks (barriers) that keep most
of the genes inactive. The mammary cell is inserted into an unfertilized sheep
egg cell that has already had all of its own genetic material removed. By
fusing the cells together tricks the egg into t ...

How Eagles Live
Number of Words: 605 / Number of Pages: 3
... and a half to seven and a half feet, and can live to be thirty or more years old. The adult golden eagle is evenly dark below, or with a lighting at the base of its tail. An immature golden eagle shows a white flash in the wing at the base of the primaries, and a white tail with a broad dark terminal band.
The golden eagle is found in the mountainous regions of the Northern Hemisphere, and is a partial migrant. The golden eagle eats rodents, snakes, birds, and can eat full-grown deer and sheep. They are now fully protected by law, but sheepherders once killed many, because it was thought t ...

Biotechnology

... pertaining to the military, whose use of it may create an
ultimate destruction. The alterance of nature is un-natural, and creates
an unbalancement in life. When we use this technology towards the
wrong side, we may all be burned. You see, Biotechnology has the
ability to altar what diseases we humans are susceptible to, and when
scientists create something to eliminate immunities to diseases, it may
result in a mass destruction of the evolved living being known as
the human. This may sound tragic, but this is what Biotechnology is
all about; changing genes so that they may fit our societal and
