.... common practice, due to lack of funds and supplies. Though recovered patients pose no serious threat, the virus is present up to 7 weeks after being treated. Vomit and diarrhea contain the infected blood and mucus so any contact with this, e.g. in poor drinking water can cause contraction of the virus. Luckily enough Ebola is not airborne and in some cases due to its self-limiting nature, it has been known to die out within a person before killing the host. In one case when a Swiss researcher found the Ebola Tai virus, she contracted it from a chimpanzee. This was during an investigation into the spur of deaths among them at the time. .....

.... thought and need and process that we engage in.” (Harry Sands and Frances C. Minters, 1977, p.2) The brain consists of nerve cells or neurons. Each neuron has an electrically charged part. It receives electrical signals from other neurons, and passes them to others. All the functions of the brain depend on electrical signals that are send from one neuron to another. The normal brain generates an electrical rhythm in order way and this order in epilepsy is broken by some neurons discharging signals. Because of some genetic defect there will occur a short electrical storm that is caused by neurons and the subject will get a seizu .....

.... geophysicists seeking to explain the phenomenon of polar wandering revived it. Since then, the modern theory of Plate Tectonics has evolved from and replaced Wegener's original thesis. Plate Tectonics is the theory that deals with the structure, history, and dynamics of the earth's crust. The earth's crust is formed of 13 continental plates. The boundaries of the zones are where tectonic activities occur, and where earthquakes and volcanic eruptions tend to happen. The plate tectonics theory was thought up in the 1960s and 1970s, with ideas taken from Wegener’s earlier thoughts. Earlier, Wegener and other scientists had noted that .....

.... bringing the remainder of the genome behind it. Most often, the entire genome isn't transferred. The bacterial genome that is delivered can be measured in minutes from the origin of transfer. That is, the amount of time it takes for a particular gene to be transferred from one bacterium to another indicated how far it is from the origin of replication. METHODS AND MATERIALS: Media Preparation: The starting material was Medium 56-glucose agar (MM560). The components of the MM56 are found in figure 1. From this, we made two types of media, complete and selective. The reagents used, along with their stock and final concentrations are found in .....

.... has not had a complete understanding of how earthquakes are caused, and what can be done to predict when they will strike. This essay will discuss how earthquakes are formed and occur, how scientists can more accurately predict the arrival of earthquakes. Before contemplating how earthquakes might possibly be prevented, it is essential that the process and formation of and earthquake be understood. Earthquakes are caused when the earth's crustal plates move, rub, or push against each other. The earth's crust (the outer layer of the earth) is made up of seven major plates and approximately thirteen smaller ones. The name plate is used .....

.... Pictures of a robin and a cardinal that we saw while stepping out of the car. We all got our gear out of the car and walked over to the trails. We had to decide what trail to take. We had three choices the first trail was half a mile long, the second trail was two miles long, and the third trail was four miles long. Since it was such a beautiful day we all decided to take the third trail that was four miles long. We started hiking around 11:00 AM. While we were hiking we heard wings flapping, we all turned and saw a robin fly towards the ground, pick up a worm, and feed it to her babies. Everyone thought that it was cute. .....

.... The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects mechanical energy from the winds that sweep along the water. This energy has been produced by the sun which warms the earth's surface and sets the air above in motion. The sun .....

.... Ranier area, a young Idahoan businessman named Kenneth Arnold spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation. According to his estimate the aircraft were approximately the size of a DC-4 airliner ( Jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying Saucer" coined by a reporter named Bill Begrette. Although not the first UFO sighting in history, Kenneth Arnolds account .....

.... drop of water---or a drop of human blood. Viruses have the most exquisite ability to sense the right cell surfaces. They don't just cause diseases in people, they infect every form of life on earth. Some emerging viruses are very serious. Common examples are the viruses, B and C. The B pattern of illness was recognized at the end of the nineteenth century, yet the virus itself was not isolated until 1963. One hundred and seventy six million people are carrying the surface antigen of this one virus globally, and the infection causes a vast amount of illness and death, including most of the fatal cases of liver cell cancer.3 To prevent .....

The families have home territories that they rarely leave. families may co-operate to catch large animals. es chase their prey. They wear them out in a long chase because they arenÕt very fast runners. Large animals are chased until the es can catch them or until the weaker ones drop back. es donÕt always get their prey, however kangaroos can lean back on their tails and kick hard enough to rip open a Õs stomach. The gestation period of the is about 63 days, and the litters average about 5 to 8 pups. After 2 weeks, the mother .....
