Carbon Dioxide Poisoning
1104 Words - 5 Pages.... and children. It does not care what color you are, nor does it care what nationality you are. The killer is carbon monoxide. Carbon monoxide, or CO as it is also called, is an odorless, colorless, and deadly gas given off when any fuel is incompletely burned by, for example, a furnace or water heater (Marable 97). Unlike a fire where you can immediately see smoke and flames, carbon monoxide poisoning gives no physical evidence of its presence. But, when taught to see and look for the warning signs of carbon monoxide, deaths in the home due to carbon monoxide poisoning can be prevented.
Sometimes, in a home the hot water supply is low, or the furnace fails to keep ....

Chlamydia 2
2145 Words - 8 Pages.... humans (it cannot synthesize its own ATP or grow on artificial medium), it was once thought to be a virus.(Hatch) Because of Chlamydia's unique developmental cycle, it was taxonomically classified in a separate order. It can thus be found with the other well-known intracellular parasites, rickettsiae, in diagnostic manuals. Until recently, however, there were no reliable and easy tests for chlamydia. Chlamydia prevention and patient care were impeded by the lack of suitable laboratory tests for screening and diagnosis. Such tests are now available. Through education, screening, partner referral, and proper patient care public health workers and health-care practitioners ....

Earthquakes

Six kinds of shock waves are generated in the process. Two are classified as body waves-that is, they travel through the earth's interior-and the other four are surface waves. The waves are further differentiated by the kinds of motions they impart to rock particles. Primary or compressional waves (P waves) send particles oscillating back and forth in the same direction as the waves are traveling, whereas secondary or transverse shear waves (S waves) impart vibrations perp ....

Chemistry
316 Words - 2 Pages.... I am the
colorless air that is breathed in constantly. I am the plunging rain tah pours
when the sun is shining, the white, damp snow that drifts in children's dreams,
and the darting hail that prevents little boys and girls to attend school. I am
the vivid part of life. I shield protection for those below me from the sun's
intense heat. I am fed and drunk by those who go through hunger. As acid
contained in the human body, I digest food and clean out wastes. I am a
desperate hope for a cure, yet poison, slowly spreading in the air and along the
land. I am the colorful fireworks "sprocketed" across the dark sky when the
touch of two soft lips are gently pressed togethe ....

The Overpopulation Of The Snow Goose In North America
1801 Words - 7 Pages.... and the Ross nest in salt marshes along Hudson Bay and then migrate down to the gulf coast states such as Texas and Louisiana. Their populations number in the millions. The third sub species is the Greater Snow Goose. They nest in the same marshes as the others except they migrate down the Atlantic Coast into the Carolinas and that vicinity. All three species have exploded in numbers since the 1950’s. Researchers have done a lot of study on the numbers and the degradation but may need to do more studies on the impact to other species and look for other options to control the populations.
Population Trends
The numbers of all "light" colored geese has been on the ri ....

This report proposes the need of security and ways in which the organisations secure their business information will be discussed.

Alcohol 2
390 Words - 2 Pages.... beverages were fermented. Scenes showing fermentation appear on pottery made in Mesopotamia as early as 4200 B.C. Mankind early discovered that drinking the fermented juices of certain fruits, berries, and grain produced an extremely pleasant effect. Among primitive peoples, alcoholic drinks increased the excitement of tribal festivals. In more civilized nations, beers and wines in the daily diet were believed beneficial to health.
During the 1800’s, a movement began in the United States to prohibit the manufacture and sale of alcoholic beverages. A constitutional amendment banning the beverages went into effect in 1920, but thousands of Americans defied the prohibit ....

Solar Cells
1163 Words - 5 Pages.... neutrons. each electron carries one
negative charge and each proton one positive charge. Neutrons carry no charge.
Every atom has the same number of electrons as there are protons, so, on the
whole, it is electrically neutral. The electrons have discrete kinetic energy
levels, which increase with the orbital radius. When atoms bond together to form
a solid, the electron energy levels merge into bands. In electrical conductors,
these bands are continuous but in insulators and semiconductors there is an
"energy gap", in which no electron orbits can exist, between the inner valence
band and outer conduction band [Book 1]. Valence electrons help to bind together
the atoms in a s ....
