CODEINE (C18 H2, NO3 H3PO4 1/2 H2O)

... of morphine, the other alkaloid in opium. Codeine is classified as a narcotic, it has the same painkiller effect as morphine but is only one-sixth to one-tenth as strong. Codeine occurs as a colorless or white crystals or as a white, crystalline powder and is slightly soluble in water and freely soluble in alcohol. The phosphate and sulfate salts of codeine occur as white, needle- shaped crystals or white, crystalline powders. Why is it used? Codeine is most useful in the relief of mild to moderate pain. It is also used as a cough rem ...

Predator - Prey Relationships

... need one another or one needs the other to survive. Symbiotic interactions include forms of parasitism, mutualism, and commensalism. The first topic of discussion in symbiosis is parasitism. Parasitism is when the relationship between two animal populations becomes intimate and the individuals of one population use the other population as a source of food and can be located in or on the host animal or animal of the other population(Boughey 1973). No known organism escapes being a victim of parasitism(Brum 1989). Parasitism is simi ...

Ants, Little But Mighty

... she start her colony? Well in the spring all the males and young winged queens leave there nest and fly high in the air and mate. The few ant queens that survive this “marriage flight” cast off there wings and instinctively begin to look for a spot to start a new ant colony. After making a nest, the young queen ant seals off the entrance and begins to lay eggs. Some of the first batch are eaten by the queen for nourishment. When the surviving eggs hatch they become like larvae. After a few weeks each larva spins a cocoon around ...

Acid Rain And Its Origins

... all the deadly toxins that go into our environment every second. Without this exploration we could kill ourselves. Not only will we kill us but we will kill off everything else. What did I pick to write on Acid rain with all the other important environmental topics? I chose it because we are subjected to precipitation all the time. I was interested to see just how dangerous acid rain is. If it really is dangerous, I was also interested to see what thing's people can do to help stop its effects. If we cannot stop the effects, I would atle ...

Religion & Evolution

... to us. We question the existence of God, or the creation of mankind rather than blindly accepting faith-filled beliefs we may received from our parents as children. Perhaps it is because we live in a nation filled with many peoples of different beliefs whose Gods are all so varied and different that it is difficult to fathom that they are all the same divine being. It is also plausible that we just have a desire to quench the thirst for knowledge that lies deep within ourselves. As for myself, I cannot believe in a being which created a unive ...

The History Of Carbon

... is diamond. Diamond is the hardest substance known on earth. Although diamonds found in nature are colorless and transparent, when combined with other elements its color can range from pastels to black. Diamond is a poor conductor of heat and electricity. Until 1955 the only sources of diamond were found in deposits of volcanic origin. Since then scientists have found ways to make diamond from graphite and other synthetic materials. Diamonds of true gem quality are not made in this way (Beggott 3-4). Graphite is another form of carb ...

Comets

... nucleus, coma, hydrogen cloud, dust tail, and ion tail. The nucleus is pretty solid and stable, composed mostly of ice and gas with a small amount of dust and other solids. The surface of the nucleus is best described as a black crust. Comet nuclei can range from 1 kilometer to about 50 kilometers across. The black crust on the surface of the nuclei helps the comet to absorb heat, which causes some of the ices under the crust to turn to a gas. Pressure builds up underneath the crust and causes the surface to bubble up in some places. Eventu ...

The Importance Of The Ozone Layer

... is really disappearing, we need to understand what it is and what it does. When ultraviolet light from 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 ...

Environmentalists

... ranger and a firefighter indicate his attachment to the wilderness that he considers “our natural home” is something very real to him. His concept of “Eco-Defense”, in which he gives a right to protect their home, is an original and unique way of thinkng of environmental protectionism. McKibben shows us the damage we have done to the natural world and makes a plea for an end. He was born to two journalist parents, married a journalist, and wrote for and edited the The New Yorker . Abbey and McKibben write differen ...

Computer Mediated Evnvironments

... has changed dramatically with the rapid diffusion of computer and information technologies throughout businesses and homes. The two most notable changes that have increased potential of linking buyers and sellers are the number of households owning personal computers (over 33% in the U.S.) and the exponential growth of applications of the Internet, most notably the World Wide Web (WWW). With increased penetration of computers, particularly multi-media computers equipped with CD-ROM drives and modems, subscription-based services such as ...

The Hippopotamus: Endangered Species Report

... reason the price-per-kilo is so slow is because hippo ivory is very brittle compared to the much stronger elephant ivory. Elephant ivory is no longer at the biggest risk for poaching; hippo ivory is. Eastern Zaire once had one of the largest hippo populations in the world, around 23,000 hippos. According to a count done in 1994, this number has now dropped to 11,000. The 1989 ban on elephant ivory is the main cause attributed to the exponential rise to hippo ivory trade. "European and African activists are petitioning advocacy groups, incl ...

Earthquakes

... accurate. This paper will discuss a little about in general and then about how predictions are made. Earthquake, “vibrations produced in the earth's crust when rocks in which elastic strain has been building up suddenly rupture, and then rebound.”(Associated Press 1993) The vibrations can range from barely noticeable to catastrophically destructive. Six kinds of shock waves are generated in the process. Two are classified as body waves-that is, they travel through the earth's interior-and the other four are surface waves. The waves are fu ...
