Ecstasy the hug drug
Ecstasy the hug drug Love Drug In America, some 5 million people regularly take some kind of illegal pill. Ecstasy, or also known as MDMA, was first developed as an appetite suppresser. Now it is used mainly for "rave life". Ecstasy not only can have an effect on a person mentally, but also physically. Ecstasy first originated in Germany as an appetite suppressant. It was never tested; therefore, when it hit the market, dieters seemed to complain of mirages, psychedelic featu...
Effect of temp on endo and ectotherms (metabolism)
Effect of temp on endo and ectotherms (metabolism) Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the...

Ebola virus
Ebola virus The Ebola Virus Cause of Disorder Ebola is a virus and part of the negative-stranded RNA family known as filovirus. It was discovered in 1976 in Africa and was named after a river in Zaire. When the virus is looked at under an electron microscope the filoviridae appear as being long, thin and occasionally they have 'branches' sprouting from one place or another. Ebola can also take the form of a 'U' or a 'b'. There are four known strains of the virus; they are Ebol...
Ebola
Ebola In the year 1976, Ebola climbed out of its unknown hiding place, and caused the death of 340 people. Fear gripped the victims faces, and uncertainty tortured their minds. The people of Zaire waited outside clinics, churches and in their homes for a treatment of the horrible disease, but there was no cure. They were forced to watch people die, hoping that they would be saved from the violent death of the Ebola virus. From the year of 1976 to the present date of 1996, researchers have se...
Ecology Assignment
Ecology Assignment 1. Explain why any one species cannot live everywhere. Any species cannot live everywhere because this would effect the natural balance. Also one species cannot adapt to all the different environments of our planet. For example a marine creature can only live underwater and cannot live on ground. 2. Explain how the activities of some species can lead to: a) an increase b) a decrease in the population size of another species. Some species act as population cont...

Three out of four people die, and the fourth person, who lives, will suffer severely. This virus is believed...
Ebola virus 2
Ebola virus 2 The Ebola virus is a member of the virus family called Filoviridae. There are three strains of filoviruses: Ebola, Marburg, and Reston. All of these diseases are very fatal to monkeys and humans. The Ebola virus is airborne and can enter the body through any opening in the skin, especially cuts. Ebola has the ability to spread from cell to cell very quickly, and kills 50 to 90 % of human victims. The mortality rate in monkeys is currently unknown. Ebola, like HIV, is said...
Ebola virus 3
Ebola virus 3 The History of the Ebola Virus There are many diseases out there that do not have a cure nor even a simple treatment. The unfortunate ones lay on their deathbed, crying out for mercy or praying for a miracle to happen. Their bodies slowly deteriorate and eventually rest in peace. The Ebola Virus is held responsible for the lives of nearly six hundred people. Back in 1976, when this so called Ebola Virus was first discovered in Zaire, very little was known about this v...
Ebola virus 4
Ebola virus 4 EBOLA VIRUS Ebola virus, a member of the Filoviridae, burst from obscurity with spectacular outbreaks of severe, haemorrhagic fever. It was first associated with an outbreak of 318 cases and a case-fatality rate of 90% in Zaire and caused 150 deaths among 250 cases in Sudan. Smaller outbreaks continue to appear periodically, particularly in East, Central and southern Africa. In 1989, a haemorrhagic disease was recognized among cynomolgus macaques imported into the United Stat...
Early synthetic polymers
Early synthetic polymers Early Synthetic Polymers Polymers have been around longer than we have. In fact, polymers are as old as life itself, as all life on earth is based on three types of polymers, namely DNA, RNA, and proteins. But this report is about some of the earliest synthetic polymers, that is, polymers made by humans, specifically, the cellulose derivatives. The very first synthetic polymer was of course leather, a modified natural polymer, an artificially crosslinked form of...
Earthquakes 2
Earthquakes 2 Earthquakes can simply be defined as a naturally induced shaking of the ground caused by the fracture and sliding of rock within the earth's crust. There are at least 6,000 earthquakes detected throughout the world each year. Many people have heard about or experienced first hand the effects that an earthquake can have. But many people don't understand what causes them and what exactly is happening during an earthquake. In the following paper I will be explaining the causes...
Earthquakes
Earthquakes An earthquake is shaking or trembling of the earth that is volcanic or tectonic in origin. "A broadly satisfying explanation of the majority of earthquakes can be given in terms of what is called plate tectonics. The basic idea is that the Earth's outermost part also called the lithosphere consists of several large and fairly stable slabs of solid and relatively rigid rock called plates" (Branely 154). These plates continuously move pushing and rubbing against each other. ...
Ebola 2
Ebola 2 In 1976, Ebola virus made it’s first appearance in Zaire, Africa, causing the death of hundreds of people. The second outbreak occurred western Sudan, also in 1976. These were large outbreaks, resulting in more than 550 cases and 340 deaths. In 1979, Ebola mysteriously re-appeared in Sudan causing 34 cases and 22 fatalities. The most recent Ebola Zaire outbreak started with a surgery on a suspected Malaria patient in Kikwit, Zaire on April 10, 1995. As in the 1976 outbreak, fu...

ESP
ESP Extra Sensory Perception Everyone knows about the five senses. Taste: the sense that allows us to enjoy an essential part of life, eating. Hearing: the sense that enables us to carry a conversation with each other. Sight: without this we not be able to do things we take for granted, like driving for instance. Touch: this detects pain and prevents us from injuring ourselves further. Smell: this helps us identify hazardous chemicals which stops us from burning our lungs. ...
Eagles 2
Eagles 2 The bald eagle is truly an all-American bird -- it is the only eagle unique to North America. It ranges over most of the continent, from the northern reaches of Alaska and Canada down to northern Mexico. The bald eagle, our national symbol, is listed as endangered under the Endangered Species Act in 43 of the lower 48 states and listed as threatened in Michigan, Minnesota, Oregon, Washington, and Wisconsin. (There are about 40,000 bald eagles in Alaska and none in Hawaii.) However, ...
Early health and medicine
Early health and medicine Early Health and Medicine Today our personal health is often something we take for granted, because over the years we have developed more advanced vitimens, medicines, and cures for numerous sicknesses. In the early days, getting sick was much more terrifying than it is today. The cures for diseases were not much healthier than the diseases themselves. Any illness in the early 19th century could be very serious , no matter how big or small. For example, tod...
Early intervention and
Early intervention and In the past children with disabilities were most often neglected, abused, and even killed. Today, however, society has become more understanding and involved in the lives, as well as the education of people with disabilities. In 1975, PL 94-142, otherwise known as The Education for All Handicapped Children Act, was the first step to providing adequate education for disabled students. Since then, many laws have been passed to increase the quality of education provided f...

And Vesicles Thousands of structures with membranes crowd the eukaryotic cytoplasm, the most numerous being called the endoplasmic reticulum (ER), a dense network of membranes running through the cytoplasm of every cell and enclosing a network of interconnected tubes (cisternae), which form a connecting channel throughout the cytoplasm. ‘Endoplasmic’ means ‘inside the cytoplasm’, and ‘reticulum...
Dsl should be the standard for telephone lines
Dsl should be the standard for telephone lines DSL Should Be the Standard for Telephone Lines There is a new technology being developed that would make standard phone lines digital instead of analog. This technology is called DSL, or digital subscriber line. Because of DSL's great superiority over our standard analog lines, all of the US's phone lines should be upgraded to DSL. One of DSL's advantages would be line sharing. Because of DSL's digital format, the data being passed over t...

Dsl DSL TECHNOLOGY Whether at home or at work, at school or on the move, we all want more speed from every service we choose to use. The theory goes that the greater the speed of service delivery we obtain to meet our daily needs - from grocery shopping to information and entertainment - the more leisure time we can create for ourselves to enjoy. The fact is that in an accelerating world, our expectations and demands keep outstripping the art of the possible and the result is frustrat...
