.... and movement (E.B. 1999) but we can not confuse the Aedes aegypti with any other mosquito for it has a very distinct look to it as well as a specific habitat. It has many related species and it’s geographic distribution is extremely wide and varied. The Aedes aegypti, with regard to both sexes, are generally similar in coloration (Womack 1993). The female adult is noticed by it’s small dark figure that is colored by white markings and banded legs. Its proboscis or snout is mostly black with regard to the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in the shape of a ‘lyre’ with two central based stripes .....

.... depression, that equates to an astonishing 15 million people. It is said that 1 out of every 6 people has had a “major” depressive episode in their life. It is estimated that it costs the nation a sum of 43 billion dollars a year in medication, lost school days, lost workdays, and professional care for depression. Tens of thousands of people out of the 15 million attempts to commit suicide because of depression and about 16,000 of those people succeed. Depression loosely defined is a disorder marked by a state of deep and pervasive sadness, dejection and hopelessness, accompanied by feeling of fatigue apathy, and low self-worth (Bourne and Russo 1998 p. .....

.... impotency in men. But out of all of these, the worst side effect of smoking is cancer; it is a life threatening disease that can affect many parts of your body at once. Lung cancer is one of the most common type of cancer caused by smoking. Smoking can cause cancer in the stomach as well in the throat. Smoking not only attacks your health, but it can also attack your pocketbook. The costs of a single pack of cigarettes has raised substantially in recent years, from 1.75 in the late '80s too nearly over $3.00 now, that’s over $20.00 a carton. Think if you smoked two packs a day for 30 years, multiply that by the price of a pack a cigarettes (think .....

.... that many people who engage in autistic behaviors have related but distinct disorders (Edelson, 1995). There is no known specific cause for , but over the years there has been a growing focus on biological etiology. Combinations of psychotherapeutic and medical treatments, as well as comprehensive educational treatment provide the best care and placement of both adults and children afflicted with .

This is a complex area which requires careful judgment by physician and patient. is a manifestation of coronary artery disease, the same disease leading to heart attacks. Coronary artery diseas refers to those syndromes caused by blockage to the flow of blood in those arteries supplying the heart muscle itself, i.e., the coronary arteries. Like any other organ, the heart requires a steady flow of oxygen and nutrients to provide energy for rmovement, and to maintain the delicate balance of chemicals w .....

.... electricity well. Weak electrolytes, like acetic acid, don’t release many ions and conduct poorly. Non electrolytes, like sugar, release no ions and form non conducting solutions. A couple electrolytes conduct electricity as solids. These solid electrolytes have ions that can move and carry charges without solvents. There are two ways to be able to have ions that are able to conduct electricity, the dissociation of Ionic Compounds, and the Ionization of Polar Covalent Molecular Substances. The Dissociation of Ionic Compounds is where particles are ionically (electrically) bonded together. They already made out of cations and anions, but in their solid s .....

.... system is no longer able to constantly maintain the natural balance that the nervous system is intended to maintain. Neurotransmitters are chemicals that nerve cells (neurons) use to communicate messages to each other. Receptors are special areas that receive these chemical messages. The key neurotransmitter in migraine is called serotonin (often referred to in the scientific literature as 5-HT or 5-hydroxytryptophan). If something interferes with the normal functioning (production, release, receptor docking, and/or re-uptake) of serotonin, that disrupts the normal functioning of the nervous system and can lead to various symptoms associated with migraine. .....

.... these years that have gone by, have lost their tail and their back legs have grown a lot. Most we see around town and in the country are green and brown. are actually many different colors. The coloring of a frog depends mostly on where the frog lives. A lot of are red, yellow, orange, black and even combinations of colors. There is even a frog that is brown with two yellow stripes down its head and back and it has bright green legs. II. Habitat of the frog If you went on a tour of the world, you would find frogs on every continent except Antarctica. The family of frogs called Ranidae, include the leopard frog and the bullfrog.
