Endangered Species Study: Jaguars
Number of words: 431 - Number of pages: 2.... are being torn down to open up lumbering, farming, livestock
raising, and other activities carried out by humans. Killing a jaguar is taking
away a life that is doing no harm to the eco-system. A jaguars' way of living
is much like that of a human, you don't see jaguars killing humans for their
skin.
III. Any endangered specie, including the jaguar, has many different
alternatives in which the government or a national group would have to be
involved. There are several organizations that help the breeding and life of
many species. One way of breeding a specific species would be to f .....

Computers-how They Affect Our Lives
Number of words: 2405 - Number of pages: 9.... when Blaise Pascal invented the first "digital calculating machine". It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector.
In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It was programmed by--and stored data on--cards with holes punched in them, appropriately called "p .....

Number of words: 1043 - Number of pages: 4.... the Mollusca phylum. It then goes under the classification of Cephalopod along with squids and chambered nautilus. From there it is ordered as Octopoda, (Family) Octopodidae, (Genus) Octopus. Then its species differ to differentiate one octopus from another. A common octopus's species is labeled as vulgaris.
A common octopus's scientific name:
Kingdom: Animalia
Phylum: Mollusca
Classification: Cephalopoda
Order: Octopoda
Family: Octopodidae
Genus: Octopus
Species: (common octopus) vulgaris
Physiology: external
The octopus's physiology is very distinct. It is so unique that .....

Geology Fo Mars
Number of words: 1330 - Number of pages: 5.... The area is pitted with numerous craters that reach between one to four km above the datum. Ejecta from the impact scatter around the crater making a rim like structure.
The northern hemisphere is very low compared to the southern hemisphere. In the north the ground level rarely reaches above one km below the datum. This stark contrast between north and south is thought to have happened 3 Gyr ago. The south was continuously bombarded with meteors. The north would get hit but it would erode or volcanic flows would cover it. The north also has evidence of ancient stream channels and .....

Nuclear Legacy
Number of words: 1091 - Number of pages: 4.... a great need for a
nuclear waste disposal site. These sites may sound frightening, but it may be
the only way for us to dispose the devastation we had longed to create. In 1986,
the decision for a nuclear waste depositary proved to be "the most frightening
decision of the decade." Of these sites, three were chosen to be the "most
suitable" for the disposal of nuclear by-products. These three sites consisted
of Hanford, Washington; Yuka Mountain, Nevada; and Defsmith, Texas.
Hanford, Washington is a low populated U.S. city, and is owned by the
Department of Energy. A low populated city is .....

Alchemy
Number of words: 3742 - Number of pages: 14.... oxide was supposed to possess marvelous powers, and it was thought that there resided within in the individualities of the various metals, that in it their various substances were incorporated. This black powder was mystically identified with the underworld form of the god Osiris, and consequently was credited with magical properties. Thus there grew up in Egypt the belief that magical powers existed in fluxes and alloys. Probably such a belief existed throughout Europe in connection with the bronze-working castes of its several races. Its was probably in the Byzantium of the fourth centur .....

Fiber Optics
Number of words: 2237 - Number of pages: 9.... of fibre optics are too often obscured by concerns that
may have been valid during the pioneering days of fibre, but that have since
been answered by technical advances.
Fibre is fragile
An optical fibre has greater tensile strength than copper or steel fibres of the
same diameter. It is flexible, bends easily, and resists most corrosive
elements that attack copper cable. Optical cables can withstand pulling forces
of more than 150 pounds.
Fibre is hard to work with
This myth derives from the early days of fibre optic connectors. Early
connectors where difficult to apply; they ca .....

Essay On Metals
Number of words: 1159 - Number of pages: 5.... brittle
and/or breaking as is the case with most harder alloys.
The disadvantages are clear. The price is high and in its pure form
it's so soft it wears quickly from the purely mechanic rubbing of your skin
and of other jewellery.
The common solution, however, is not without its flaws. "Cutting"
the gold with cheaper metals can mean dramatic savings in material cost and
highly improved resistance to wear but we must remember that it also
changes the other special property of gold - its resistance to corrosion.
Some chemicals in more-or-less popular use in body-piercing circles

Evolution From A Molecular Perspective
Number of words: 3032 - Number of pages: 12.... that person? These are all
issues that will have to be dealt with in the near future, but for now we need
only concern ourselves with the objective observation of these proteins in our
attempt to explain our ever mysterious origin. As humans, we are the first
creatures to question exactly where we came from and how we got here. Some
cling to religious creationism as a means, while others embrace the evolutionary
theory. As of now, and possibly forever, neither can be proven to be absolute
truth with hard facts, and both have their opposing arguments. The point of
this paper being compo .....

Nucleic Acids
Number of words: 425 - Number of pages: 2.... monomers of RNA and DNA are called nucleotides. Each nucleotide has three parts:
A Five Carbon or Pentose Sugar
The sugar will be one of two very similar pentose rings. Ribo contain the sugar ribose. Deoxyribo contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions.
The Nitrogen-Containing Bases
There are two types of bases found in nucleic acids. The purine bases have two nitrogen conta .....
