... of Provera are not effective. For the body to produce steroid hormones it must convert cholesterol into estrogens and other related substances. In order for this process to take place, several steps are involved which are controlled by a certain enzyme. In knowing this, Lee wanted to find out if blocking the action of an enzyme would be reached with high doses of Provera.
What Lee and Auchus found out was that Provera could inhibit certain enzymes, (3HSDII) which influence hormone production, that low doses of Provera could disrupt GnRH production and high doses were needed for a therapeutic effe ...

... of the historical uses of marijuana may have contemporary relevance. As I stated before, there are very few ways to study something that the society feels is harmful to the subject.

This historical point-of-view allows our conscience to be at ease so that accurate tests can be performed to conclude a up to the date analysis. For so long marijuana has received criticism due to the abuse it took in the sixties and seventies. During the generation drought of knowledge of the subject, we have become ignorant to ...

Number of Words: 326 / Number of Pages: 2
... The cell theory has three parts:
1. All organisms are composed of cells.
2. Cells are the basic units of structure and function in organisms
3. All cells come from preexisting cells.
The impact on science was very great due to the discovery of cells and
the cell theory. Many or all things were effected by the discovery of cells,
everything was looked upon in a different way. Some people still did not
believe that all living organisms were made of tiny microscopic chambers called
cells. Many people thought that people that believed in cells were insane, some
people even wanted to put Anton ...

Information About Transgenic Organisms
Number of Words: 329 / Number of Pages: 2
... analyzing the function of gene products because a specific gene can be expressed in all the cells of a transgenic organism and the effect on the organism's development and function can then be monitored. It is also possible to use transgenic procedures to produce animals in which a specific gene has been deactivated in all its body cells. Certain genetic disorders of humans can be studied with this technique in laboratory animals if the disease-associated gene occurs naturally in both humans and an appropriate study species, such as a mouse. In such human disorders, symptoms are caused by natural dysfu ...

... scanning capabilities. The multispectral mode captures data in three bands in the following spectral ranges: .50-.59, .61-.68 and .79-.89 micrometers. The three bands are co-registered and have a ground resolution of 20m. The panchromatic mode images data in the spectral range .51-.73 micrometers at a sampling interval of 10m.
LITERATURE REVIEW
Landsats 1 through 3 circled the Earth every 103 minutes, completing 14 orbits a day. Eighteen days and 251 overlapping orbits were needed to provide almost complete coverage of the Earth’s surface. They carried return beam vidicon (RBV) cameras and th ...

c. Whether there is a suitable work force in the area for
plant construction and operation;
d. Whether there is sufficient energy resources readily
available;
e. Whether or not the chemical plant can carry out its
operation without any unacceptable damage to the
environment.
Listed above are the basic deciding factors that govern the location of
a plant. The following will explain in greater detail why these factors
should be considered.
1) Raw Materials The plant needs to be close to the raw materials that are ...

Genetic Disorders

... brain causes these symptoms and later results in death.
Another single-gene disorder is the Tay Sachs Disease. People who
inherit the faulty Tay Sachs gene lack a crucial enzyme that is needed to break
down fatty substances in brain and nerve cells. As a result, these substances
build up in such large quantities that the central nervous system
gradually stops functioning and the person dies. Symptoms usually become
evident within the first six months of life, and most children die before reaching the age of four. 1 in 3,600 people of eastern European Jewish ancestry carry it.

Asteroid Defense

... could do to our planet it is usually a very scary thought. In the past
we have been very lucky with where asteroids have hit our earth. Back in 1908
in the Tunguska region of Siberia, an object from space hit there causing miles
of forest to be devastated. If that same object had hit New York, it would have
probably been like a 20 megaton bomb going off in Times Square. That would have
completely altered history. What makes it worse is that it is thought that a
small comet hit in Tunguska. What if a huge comet had hit there? These
examples are very good reasons why I think that humank ...
