Global Warming
.... in response to human activities, but rather where (regional pattern), when (the rate of change) and by how much (magnitude). (17,18).
Alarming information and trends are leading the scientific community in this same belief. The concept of global warming is predicting detrimental events for the future.
The most prevalent issue of global warming is the increase in overall world temperature. In the thirty year time period of 1951-1980, a 0.4C temperature increase has been documented (Hansen 36). Michael D. Lemonick predicts that unless the world takes immediate and extreme steps to reduce the emissions of heat-trappi .....

The Noble Gases
.... lamps, and lasers.
Argon is the most abundant and most used noble on earth. Sir Walter Ramsey discovered it by Lord Rayleigh and in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and fluorescent tubes. It is also used a lot in industry.
Krypton a very rare noble was discovered by Sir Walter Ramsey and by Morris W. Travers. Traces of it are found in natural gas, hot springs and volcanoes but most of it is in the atmosphere. It is used for incandescent lights and it is used in high speed photography.
Xenon is the first noble to .....

Magnesium, Beryllium, And Calcium
.... Earth’s crust. It is essential for forming leaves, bones, shells, and Portland Cement. Calcium occurs in many highly useful compounds such as marble, limestone, and chalk.
Plants and animals must have calcium to live. A plant cannot grow without a good supply of calcium. A lack of calcium prevents bones from developing properly. Calcium is the major component of teeth and bones. Calcium must be present for blood to clot. It also helps the nervous system, and it is necessary for muscle contraction. A good dietary intake of calcium is essential for proper growth and development. Calcium’s role in maintaining good vision i .....

Coelacanths
.... being such rare fish, coelacanths have very great zoological importance. First, they are "living fossils"-a life form that has been preserved almost unchanged for many millions of years. As such, they offer the scientist a view of the biology of an earlier stage in the history of life. Second, the group of fishes to which the coelacanth belongs occupies an extremely important place in the vertebrate life. They include the ancestors of all land forms, including man himself.
The earliest fossil coelacanths almost certainly lived in freshwater, but later they entered the oceans. They probably live in quiet deep waters, co .....

The Study Of Biology
.... deals with the functions of the cell and the basic strucural unit of living matter; Finally, population biology became firmly established as a major sub division of biological studies in the 1970’s. This field relates with the study of gene changes in populations, and ecology.
Biology also includes the study of humans at the molecular, cellular, and organismal levels. If the focus of examination is the application of biological knowledge to human health, the study is often termed biomedicine. Human populations are by convention not considered within the province of biology; instead, they are the subject of anthropolog .....

Earthquakes
.... 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 perpendicular to their direction of travel. P waves always travel at higher velocities than S waves, so whenever an earthquake occurs, P waves are the first to arrive and to be recorded at geophysical research stations worldwide.(Associated Press 1993) Earthquake waves were observed in this and other ways for centuries, but more scientific theories as to the causes of quakes were not proposed until modern times. One such concept was a .....

The Origin Of Humanity
.... is hypothesized to be the human evolving. Evolving from what though? The theory of evolution states that creatures change overtime to suit their surroundings. This is called environmental adaptation. The more a creature can adapt to it's environment the greater chance it has of living and show an increase in population called survival of the fittest.
A theory developed by a scientist named Charles Darwin who had conducted extensive research into the environmental adaptions of animals, for example the adaptation of the galapagos turtles from short neck to long neck so they could reach their food. This theory helps to prove th .....

Yeast
.... like any other organism, in order for yeast to survive they need to have a significant amount of nutrition. Unlike plants, yeast lacks the chlorophyll needed to create its own food. It feeds on the sugar of many different resources to stay alive. Some of the most popular are different fruits and nectars. Also, molasses seems to be a prime choice as the feeding ground for yeast.
When the yeast has finished retrieving nutrients from the sugars, it produces enzymes which are used in many different ways. Some yeast break down sugar in alcohol. This is what is known as fermentation.
Fermentation .....

Psychology

Those employed in hospitals, nursing homes, and other health facilities may work evenings and weekends, while those who work in schools and clinics generally work regular hours. Psychologists employed as faculty by colleges and universities divide their time between teaching and research and a few have administrative responsibilities as well. Most psychologists in government and industry have structured schedules. Psychologists often work alone, reading and writing report .....

Oil Spills And Pollution
.... of dead birds was 33,126 along with 138 eagles and 980 otters.
Usually, when we are thinking of oil pollution what comes to mind is maybe a disastrous oil tanker spill somewhere in an ocean that ends up killing thousand upon thousands of wildlife living in that region.
One example of this is the Exxon Valdez which spilled oil from its tanker into Alaskan waters and dumped 1.5 million gallons of fuel. (maybe you’ve heard of this)
Many kinds of oil can be spilled into the soil causing it to pollute local groundwater sources for human and animal consumption. This can result in many serious illnesses and if not treated proper .....

To What Extent Does Acid Precipitation Affect Annelids?
.... in the lowering of the acidity of rain.
Earthworms (Annelids) are a species of worm which are many segmented. They live in damp soil, usually forming intricate tunnels beneath the surface. Their bodies are lond and cylindrical, and have "bluntly tapered ends and are somewhat depressed posteriorly." (Storer, et. al, (1972) General Zoology 5th ed., McGraw Hill Books.) As earthworms burrow, thew swallow large quantities of earth that often contain large amounts of vegetable remains, often depositing, or casting, their very nutritive remains to the soil, which adds to it's enrichment. The first person to truly recognize the impor .....

Black Holes
.... According to images from the Hubble Space Telescope, the black hole is 20 light-years from the center of the galaxy, but since the black hole is so massive it is hard to explain how it could have been moved. One idea is that the black hole is moving itself. Some astronomers think that the disk of dust serves as a "fuel tank." The black hole sucks in the material which is absorbed by gravity, compressed, and heated to tens of millions of degrees. This theory would explain why radio telescopes have observed radio jets, or hot gas exhausts from the black hole's area. The exhaust may be pushing the black hole across space, a .....
