Skin Cancer

UV radiation is higher today than it was several years ago. Ozone serves as a
filter to screen out and reduce the UV light that reaches the earth's surface
and its people. Very simply, sunburn and UV light can damage the skin and lead
to skin cancer (1., p 1). The American Cancer Society also faulted repeated
exposure to x-rays, artificial forms of UV radiation like tanning beds, and

Sleeping Disorders

Thirty-three percent of adults in America have a case of insomnia at least once
in their life. Most cases only last one or two nights, but insomnia can

There have only been three standard types of insomnia that have been
identified by doctors. They are as follows:

ejected when the victim coughs. The disease can be transmitted by dried small
pox scabs and through materials the infected person has come in contact with.
The virus is reproduced in the lymphoid tissue and released into the body.

host cell. The virus must interact with a receptor on the cell surface. The
infectious cycle usually consists of two stages. The first stage makes the
proteins neces .....

in the cortex of the adrenal gland in humans, regulate protein and carbohydrate
metabolism. Aldosterone, another steroid produced in the adrenal cortex, plays
a role in the mineral and water balance of the body.

Stress

companies have become mean and lean. Employees are compelled to be more
efficient; they find themselves taking on the work of what used to be two. The
result is longer hours, less time for outside activities, and consequently
increased stress.
According to Business Week, the typical American works 47 hours a week, and if
current trends continue, in 20 years "the average person would be on the job 60
hours a week." Another factor that increases stress is technological
advancements. With all the .....

Coping With Stress In An Organization

physical adjustment.” Many people think of stress as always being something bad.
However, stress sometimes can be good. Stress is part of our every day life.
It can have a motivating effect or a demotivating effect. Each of us have our
own level of how much stimulation or stress we need in our lives to keep us from
getting bored.1 Others however, have a much lower tolerance for stress stimuli.
So managers must be able to look at each individual and decide if the individual

Another, more common, form of color blindness is called dichromatism.
People with di-chromatic vision tend to confuse red, green, and gray, but can
easily distinguish blue and yellow. Some cannot even see the longest wavelengths
of light -- the red end. Though it is rare, others cannot see the short
wavelengths, near the violet end. These people tend to confuse blue, yellow .....

Teen Smoking

conversation, it became clear that most teens smoked for two seemingly
contradictory reasons: They want to be part of a peer group, while rejecting
society and its norms. They want to reach out and rebel at the same
time."(Roberts 38) Tobacco companies spend four billion dollars each year in
advertising and promotional costs and claim there is no health risk. Six hundred

The Differences And Similarities Of Pneumonia And Tuberculosis
.... Pneumonia is a serious infection or inflammation of the lungs with
exudation and consolidation. Pneumonia can be one of two types: lobar pneumonia
or bronchial pneumonia. Lobar pneumonia affects one lobe of a lung while
bronchial pneumonia affects the areas closest to the bronchi (O'Toole, 1992).
In the United States over three million people are infected with pneumonia each
year; five percent of which die.
Etiology
There are over 30 causes for pneumonia however there are .....

When you think of someone who uses steroids you typically picture
someone who is massive, and whose muscle mass is very well defined. A picture

because his biceps are in the way, but he can manage to bench press his car.
The possible growth and development is amazing. With much less work necessary,
the results can be astounding. Athletes can get bigger, stronger and faster,

The Three Layers of Muscle
The heart has three layers of a muscular wall. A thin layer of tissue,
the pericardium covers the outside, and another layer, the endocardium, lines

Although the article fails to mention how, "Jost deduced that two secretions
from the fetal testis are essential for male development - Mullerian-inhibiting

Mullerian-inhibiting substance is still unclear to scientists. Problems with
improper levels of this hormone result in genetic and phenotypic reproductive
disorders.
