Hurricane Floyd
... is in the western Pacific Ocean than it is called a typhoon. One in the Indian Ocean is called a cyclone. The danger region of a hurricane is normally in the Gulf of Mexico or the Atlantic Ocean. The hurricane season is the six month time period from June-November. The peak month of hurricanes is September.
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded int ...

Klinefelter Syndrome
... cell separate, ulimatiing producing two new cells having 23 chromosomes each. Before meiosis is completed, however, chromosomes pair with their corresponding chromosomes and exchange bits of genetic material. In women, X-chromosomes pair, in men, the X and Y-chromosomes separate, and meiosis continues. Otherwise it is not something that happens by the law of nature in which you are randomly chosen in its specific frame of how many times it happens, whom it effects, and how it happens. There is really no specific frame in which it invariably happens. It is known through that it happens during the process of meiosis in which chromosomes split.

Chesapeake Bay Pollution
... throughout the Bay. The oyster and blue crab catch, however, continues to dwindle, and some find fish populations have declined. Species, such as striped bass have increased to the point that they are commercially viable again.
The Chesapeake Bay's decline was evident as early as the 1950s. In the late 1970s, state and federal scientists began an extensive study to determine the reasons for the Bay's decline. Three major problems were identified; excess nutrients from wastewater, agricultural lands, and developed land; sediment in runoff from farms, construction sites, and eroding lands; and possible elevated levels of toxic chemicals.
Nitrogen and phosphorus are ...

Humpback Whales
... individual whale, like a fingerprint. The humpback's skin is freqently scarred and may have patches covered with diatoms.
Humpback whales have 14-35 throat grooves that run from the chin to the navel. These grooves allow their throat to expand during the huge intake of water during filter feeding. They have small, round bumps on the front of the head edging the jaws.
Humpbacks have huge, mottled white flippers with rough edges that are up to one-third of its body length; these are the largest flippers of any whale. The humpback's genus, Megaptera, means "huge-wings," referring to its flippers. The flippers may have barnacles growing on them.

Mononucleosis
... the ages of 15 and 30. Both men and women are affected, but studies suggest that the disease occurs slightly more often in men than in women. Doctors estimate that each year 50 out of every 100,000 Americans have symptoms. Among college students, the rate is several times higher. does not occur in any particular "season," although authorities in colleges and schools, where the disease has been well studied, report that they see most patients in the fall and early spring. Epidemics do not occur, but doctors have reported clustering of cases. Transmission: EBV, the virus that causes most cases of , infects and reproduces in the salivary glands. It also infect ...

Klinefelter Syndrome
... described this condition in 1942, it was not until 1956 that other researchers reported that many boys with this description had 47 chromosomes in each cell of their bodies instead of the usual number of 46. This extra sex (X) chromosome causes the distinctive make-up of these boys. All men have one X chromosome and one Y chromosome, but sometimes a variation will result in a male with an extra X. This is and is often written as 47,XXY. There are other, less common variations such as 48,XXYY; 48,XXXY; 49,XXXXY; and XY/XXY mosaic. All of these are considered variants.
The major effect of the extra X chromosome in boys with seems to be the function of th ...

Acetylation Of Ferrocene
... disparate products. Not only do we get acetylferrocene, but we
also get diacetylferrocene, some unreacted ferrocene reactant, and acetic acid
as well. We will use thin layer chromatography (TLC), column chromatography
(CG), and IR spectra analysis in order to determine the what proportions of
each of these compounds will be present in the final product.
Both TLC and CG are excellent methods of measuring the presence of a
given substance. Both methods turn around a compounds polarity. As one recalls,
polarity is a measure of the electronegativity of a compound determined by their
placement in the periodic chart. Specifically, in this lab we are talking about ...

Plate Tectonics
... Among the seafloor features that supported the sea-floor spreading hypothesis were: mid-oceanic ridges, deep sea trenches, island arcs, geomagnetic patterns, and fault patterns.
Mid-Oceanic Ridges
The mid-oceanic ridges rise 3000 meters from the ocean floor and are more than 2000 kilometers wide surpassing the Himalayas in size. The mapping of the seafloor also revealed that these huge underwater mountain ranges have a deep trench which bisects the length of the ridges and in places is more than 2000 meters deep. Research into the heat flow from the ocean floor during the early 1960s revealed that the greatest heat flow was centered at the crests of t ...

Damn Near Everything There Is To Know About Cells:
... muscle and nerve tissues. Plant tissues include those
of the stem and root. Many cells in tissues are linked to each other at
contact sites called cell junctions. Cell junctions help maintain differences
in the internal environment between adjacent cells, help anchor cells together,
and allow cells to communicate with one another by passing small molecules from
one cell to another. Groups of two or more tissues that function together
make up organs. An organ system is a group of organs that work together to
carry out major life functions.

Air Pollution
... to control pollution, initiated during the 1950s, resulted in the successful elimination of such sources of pollution as industrial effluents and the outdoor burning of trash and debris. Nevertheless, pollution continued to increase as a result of the increased number of motor vehicles. Exhaust fumes from the engines of automobiles contain a number of polluting substances, including carbon monoxide and a variety of complex hydrocarbons, nitrogen oxides, and other compounds. When acted upon by sunlight, these substances undergo a change in composition producing the brown, photochemical smog for which Los Angeles is well known. Efforts to reduce pollution from a ...
