Water Transitions
Words: 687 - Pages: 3.... seventy percent of the earth's
surface (Groliers). Sea water doesn't just contain hydrogen, oxygen,
sodium, and chlorine; it also contains every naturally occurring element.
Although seawater has a fairly constant ratio of major elements, salinity
and seawater can fluctuate. Normally, the salinity is thirty-four to
thirty-seven parts per thousand (ppt.), but on a particularly rainy morning,
the salinity may decrease to something as low as thirty-two ppt. (Stuller
29).
The mixing of freshwater and sea water forms a third type of water,
known as brackish water. Brackish water can be found in a variety of
mixing zones such as river del .....

It was identified by Albert Magnus about 1250, and he described the way to manufacture it. Since then the method has scarcely changed: the mineral arsenopyrite is heated and decomposes with the liberation of gas. The gas can be condensed on a cold surface. Metallic was first produced in the 17th century by heating with potash and soap.
General Properties

Cells
Words: 358 - Pages: 2.... It is in the cytoplasm where all of the other
organelles are stored. There are six main organelles in the cytoplasm. First,
the mitochondria, which provides energy to the cell through ATP and respiration.
Then there is the endoplasmic reticulum which separates parts of the cell. Then
there is the Golgi apparatus which is used for sorting, storing, and secretion
for the cell. Next are lysosomes, which hydrolyze macromolecules. Then there
are centrioles that play a major role in cell division. And lastly there are
vacuoles which have a variety of storage functions.
The plant cell is similar in most ways. The only really big di .....

Coral Reefs 2

Atolls, on the other hand, are formed far offshore and they make a ring-shaped reef that close a circular lagoon. Coral reefs are the largest biological structures on the planet, with the largest being the Great Barrier Reef covering over 2000 kilometers along the East Coast of Australia. The reef is said to be 500,000 to 2,500,000 years old and is said to be visible from the moon. There is only one problem with this beautiful structure and that is the carelessness of man. Silt from deforested lands and pollution from cr .....

Science
Is global warming occurring?
- According to Accu-Weather, the world's leading commercial forecaster, "Global air temperatures as measured by land-based weather stations show an increase of about 0.45 degrees Celsius over the past century. This may be no more than normal climatic variation...and several biases in the data may be responsible for some of this increase."
- Satellite data indicate a slight cooling in the climate in the last 18 years. These satellites use adv .....
