Manatee
Number of Words: 343 / Number of Pages: 2
... pinkish calf is born.
Manatees ferquently communicate by muzzle to muzzle contact and when alarmed
they emit chripy squeaks.
The number of manatees has been reduced over the past several years due
to heavy hunting for their hides, meat, and blubber oil. Some governments,
including the United States, have placed the manatees under the endangered
species list. One practical reason for this is that they have proved useful in
clearin girrigation and transport channels clogged with aquatic plant life.
There has also been an increase in manatee death due to passing boats that speed
through channels. ...

Hepatitis B Virus

... pol, env, pre-core and X that respectively encode the viral DNA-polymerase, envelope protein, pre-core protein (which is processed to viral capsid) and protein X. The function of protein X is not clear but it may be involved in the activation of host cell genes and the development of cancer.
Hepatitis B is a serious public health problem that affects people of all ages in the United States and around the world. Each year, more than 240,000 people contract hepatitis B in the United States. A highly infectious virus that attacks the liver causes the disease. (HBV) infection can lead to severe illness, l ...

Arthritis, The Hidden Dissability
Number of Words: 1543 / Number of Pages: 6
... for which something can be done.
Types
As I have already stated, there are more than 115 different types of arthritis. I will include the six most common forms in this report.
Osteoarthritis
Osteoarthritis is the most common form of arthritis in Canada. This type is also referred to as "degenerative joint disease", because it is a consequence of the wearing out of the cartilage that covers the end of bones, usually in the major weight bearing joints of the hips, knees, and spine. Joints in the fingers are occasionally involved as well.
Osteoarthritis usually occurs later in life ...

... important because it corresponds with the firs t appearance of
abundant fossils especially Trilobites, which characterizes a succeeding point
in time. During the Cambrian Period the lapetus Ocean appeared, the
predecessor of the Atlantic Ocean, which separated the young North American and
Eurasian continents. Also Gondwanaland was in the final stages of development.
Gondwanaland was a very large continent made up of what is now South America,
Africa, Arabia, Madagascar, India, Australia, and Antarctica. Large shelled
organisms first emerged during the Cambrian. Also Earth¹s atmosphere contained ...

Rutherford's Gold Foil Experiment
Number of Words: 787 / Number of Pages: 3
... most notable achievement. It not only
disproved Thomson's atomic model but also paved the way for such discoveries as
the atomic bomb and nuclear power. The atomic model he concluded after the
findings of his Gold Foil experiment have yet to be disproven. The following
paragraphs will explain the significance of the Gold Foil Experiment as well as
how the experiment contradicted Thomson's atomis model.
Rutherford began his experiment with the philosophy of trying "any dam
fool experiment" on the chance it might work.1 With this in mind he set out to
disprove the current atomic model. In 1909 he a ...

Collisions Of Two Objects
Number of Words: 217 / Number of Pages: 1
... which says the total momentum of an
isolated system is the table and the balls, and the law then implies that the
total momentum of the balls just before they collide is the total momentum just
after the collision.
Therefore if the masses of two colliding objects are known, the velocity
and the velocity of the other before the collision, you can calculate the final
velocity of this second object after it has collided. To obtain an exact answer
however, we must find out what type of collision takes place, whether it is
elastic or not elastic.
The type of collision is characterized by what i ...

... retirement, the elimination of cash, the restructuring of education, industry and a movement to global politics, economics and world government.
In particular this paper will suggest that the Christian Judao work ethic with society’s goals of full employment in the traditional sense is no longer appropriate, necessary or even possible in the near future, and that the definition of work needs to be far more liberal. It argues that as a post market era approaches, that both government and society will need to recognise the effects of new technology on social structure and re-distribute resource ...

Creation, Evolution And Intervention: Which Theory Is Correct?
Number of Words: 1632 / Number of Pages: 6
... theory that groups of organisms can be transformed into different organisms
has been suggested many times since the early 1800s, when scientists began
looking for evidence that the evolution process took place. "The most
outstanding evolutionists in the nineteenth century was Jean Baptist de Lamarck,
who argued that the patterns of resemblance arose through modifications of a
common lineage-for example , that lions tigers and others all descendant from a
cat like ancestor." (Dickey p.42) It had already been a widely accepted theory
that different animals adapt to different modes of life and environm ...

Rates Of Reaction

... of a particle is increased with heat. The particles
which have to have the activation energy are those particles which are moving,
in the case of magnesium and hydrochloric acid, it is the hydrochloric acid
particles which have to have the activation energy because they are the ones
that are moving and bombarding the magnesium particles to produce magnesium
chloride.
The rate at which all reactions happen are different. An example of a fast
reaction is an explosion, and an example of a slow reaction is rusting. In any
reaction, reactants chemical reactions® products.
We can measure reactions ...

Eagles 2

... marshes, or other wetland areas. Nests are often reused year after year. With additions to the nests made annually, some may reach 10 feet across and weigh as much as 2,000 pounds. Although bald eagles may range over great distances, they usually return to nest within 100 miles of where they were raised.
Bald eagles normally lay two to three eggs once a year and the eggs hatch after about 35 days. The young eagles are flying within 3 months and are on their own about a month later. However, disease, lack of food, bad weather, or human interference can kill many eaglets; sometimes only about half wi ...
