.... are actually more closely related to storks than to the vultures of Europe, Asia, and Africa. Turkey vultures are remarkably successful birds. They range everywhere from parts of Canada and much of the United States to South America. At home in deserts, prairies and woodlands, they have even settled close to people in a number of urban and suburban areas. Observed in flight, the turkey vulture appears black with the underside of its wings grayish or silvery, giving the birds a two-toned appearance. They characteristically hold their wings in a slight V, or dihedral, thus aiding identification. On rare occasions, they hold t .....

.... ant is believed to cause a total yearly loss of $5 million in the United States (unison services. 1998). There are about 9,500 named species of ants. These ants are divided into 16 sub families and 300 genera, all which belong to the family called Formicidae, the family of ants (Hoyt. 1996). The leaf cutting ant belongs to the genus called Atta. There are fifteen different species of Atta and all are limited to the new world (Holldobler & Wilson, 1994). The leaf-cutter ant looks pretty much like a regular ant in North America except that it is a little bigger than most ants. Looking at the ant in the untrained eye a person usuall .....

.... tube, magnets and charged plates, he sent ray particles through various experiments changing the position of the charged plates. By changing the plates, he discovered he could also change the point at which the particles would hit a florescent screen at the end of the tube. He decided that the ray was made up of particles with a negative charge. He named these particles electrons. This discovery also showed that atoms had a substructure. Thomson made a model showing his idea for the atom. His model, called the raisin dough model had positive and negative particles imbedded into a positive atom. Other particles in the atoms n .....

.... ("hyper" = too much, "glycemia" = glucose in the blood). Hyperglycemia causes intense thirst, the need to urinate frequently, blurred vision, fatigue, and other symptoms. Over time, high blood glucose can cause very serious medical problems. Adding up the total toll of complications, the disease is one of the nation's leading causes of death. All complications can be largely prevented by practicing what is known as "tight control," keeping your blood glucose level as close to normal as possible. This takes time and energy, but many diabetics do it successfully and live full lives without much trouble. Scientists don't k .....

.... ethyl 4-aminobenzoate were to be separated by extraction from an ether solution. Once the separation took place, and crystallization was carried out, it became possible to determine what components were in the unknown mixture, by means of a melting point determination. Results Procedure Observations Inference Dissolve 3.05g Phenol Mixture was a golden-Neutral acid in 30ml brown/yellow color t-butyl methyl ether in Erlenmeyer flask and transfer mixture to 125ml separatory funnel using little ether to comp .....

.... of our homes that could never be done before; such as talking with distant friends and relatives, buying merchandise, doing research, and a steadily increasing number of other things. At nearly any time of day we can buy something with a credit card, or fill out a form with personal information such as a loan application, job application or insurance form. Years ago, sending this amount of personal data was impossible. Now, with the advances of computer technology, we can do what we were once not able to do; such as getting in touch with the bank and transferring money while we are miles away from the banks. Comp .....

.... the time food is digested in the unusually short intestine system of a shark. Sharks sexually reproduce. Unlike a shark, rays have flattened bodies so they can hide themselves in the sand at the bottom of any shallow water area and wait for a meal. Rays also have a whiplike tail for defense and jaws, which it uses to crush mollusks and crustaceans. Class Osterrichhthyes has the most separate species of any vertebrate class. Unlike their oceanic cosines Bony fish have a skeleton made from calcium phosphate and a slimy skin covered by bony armorlike scales. Fish of the Osterrichhthyes class have gill flaps call an operculum .....

.... USA, finally dissipating near the city of Monterrey. During its most intense phase at the western end of the Caribbean Sea, Gilbert was estimated to have central pressure of 885mbar, and maximum sustained winds in its circulation over 150kt (knots) with highest gusts in excess of 175 kt. The central pressure outrivalled the 899 mbar of the Florida Keys hurricane of 1935. Gilbert, at that stage an un-named tropical depression with maximum sustained winds around 30kt, was first spotted on Thursday 8 September some 300km east of Barbados. It brushed past Barbados and St Lucia the following day with limited wind-damage and some floo .....

.... the nucleus and the membrane, there is a polysaccharide matrix called the cytoplasm, where organelles can be found. The organelles are attached to a framework. The cell’s cytoskeleton. Every living cell has the ability to detect signals from it’s environment. The signals are usually in the form of chemical molecules, that the cell has learned to recognize. The cell decodes these molecules into messages, and acts upon them. The cell has a “language”. Signals and messages are carried by particles of matter that have a very low energy requirements. There are many, many signals rumbling around the cell. It was thought t .....

.... government would have to assume a major share in their construction. Motivated by the search for the multiple use of water resources, including navigation, flood control, and irrigation, in addition to power production, the Tennessee Valley Authority, or TVA, started government participation in large-scale waterpower development in 1933. Most major installations depend on a large water-storage reservoir upstream of the dam where water flow can be controlled and a nearly constant water level can be assured. In contrast to storage-type plants, which depend on the impounding of large amounts of water, a few examples exist where both .....
