... in the electrostatic force law. One idea was that there are two types of electricity, which were later named positive and negative by Benjamin Franklin. Another idea was that electric samples of the same kind repel each other, and those of different kinds attract each other. This later was named the law of electrical charges, and is essential to the understanding of electricity. A third idea was that if the distance between electric charges is increased, the force of attraction or repulsion decreases. All matter is made up of very tiny particles called atoms. Atoms are made up of even smaller substances called sub ...

... Adrenaline affects many different types of tissues throughout the body. The release of adrenaline prevents hypoglycemia (low blood sugar), by binding adrenergic receptors in the hormone releasing cells of the pancreas. Epinephrine is called the “fight� or “flight� hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the bo ...

... have frozen, and there would be no life on earth. The Washington Post has reported that the earth is warmer than it has been in 1,200 years.2 Recently, the summer of 1999 set records for heat in much of the United States. The average world temperature has increased one degree Fahrenheit over the last 120 years, making the world hotter than it has been in 100,000 years. From the beginning of the industrial revolution, concentrations of carbon dioxide have increased by 30%, concentrations of methane have doubled, and nitrous oxide has risen by 15%. The increases of these chemicals have enhanced the heat trappi ...

... because they increase and improve our supply of medicines, foods, building materials, and other products made from plants. If one were to try and pin-point the most important thing a botanist does, it would be impossible. They do so much for us, yet get little recognition for it. Whenever you take an aspirin, eat some vegetables, or even sleep in the house that was once built, you can thank a botanist for it all. Many people, such as myself, would wonder why someone would want to be a botanist. The main reason anyone can name is that plants have intrigued people for thousands of years. Plants are used for de ...

... The increase of the population of a species is caused by the predator when it stops feeding on a species lower than the predator in the food chain. So when the predator stops or reduces the amount of feeding on a species, the population of the species would start to increase. 3. It is seldom possible to count all the individuals in a given space. Explain one method by which biologists can study population densities without obtaining such data. Scientist barely ever count the amount of individuals in a certain area because it would take too much time. Instead of actually counting the number of individuals in an ...

... clones would be mindless zombies, Frankenstein monsters, or 'doubles.' This is all nonsense. Human clones would be human beings like you and me . . . They would be carried and delivered after nine months by a human mother . . . Consequently, a clone twin will be [years] younger than the original person. (1) Whether or not scientists should or should not clone humans is a tough question to answer. Legally, are scientists able to make clones? The answer is no. Should scientists be able to make a headless human? (body parts) Yes, as long as no law exists banning headless humans. Before going into this cont ...

... of what is now known as the computer were made by the United States military in the 1940's and 1950's. The needs of the military at the time required that a system be created that could aid in the aiming of ballistic military equipment. Today’s modern computers are undoubtedly the result of the United States military’s early developments and technological advancements in computing. Because of the military’s need for the computer earlier this century, great advancements have been, and will continue to be made in the way of computers and other technologies. Truly the first computers, or tools made with t ...

... Romans based their system of gods on what they believed was up in the sky. Zeus and the other gods and goddesses were based on the planets that were visible to the people of that time. Astrology was also popular in Babylon, Egypt, the Middle East, and China. Modern Astrology has changed as new planets have been discovered. Astrology is about the interaction between the planets, including the Sun and the Moon, and the Star Signs. It studies the mathmatical cycles on which these interactions are based. In some ways, the forces between the planets involved in Astrology can be simplified into one word : gravity. The S ...

It also contains information from a newspaper article about a new monitoring site for acid rain in Irish Cove locat ...

... the sun hits the earth's atmosphere, it hits and divides the oxygen molecule (O2). Each molecule then attaches with other oxygen molecules to form O3. O3 is ozone. So when ozone is formed, harmful rays from the sun are absorbed. The O3 molecule is very reactive and it bonds easily with other molecules it the atmosphere. When and oxygen atom from the ozone reacts with a chloride ion from chlorine monoxide, the ozone molecule is destroyed. So chlorine monoxide is an ozone destroyer. There is always a certain amount of chlorine monoxide in the atmosphere. It is important to remember that ozone is constantly being c ...
