.... has to exert dominance over other males. This can also be verbally, intellectually, physically, and aesthetically. In our society we have always praised the athletes that achieve the most amazing physical feats or that have achieved cosmetic perfection. Lets face it, having large muscles enhances confidence, strength, and physical attraction from the opposite sex which can lead to positive popularity. Being extra strong can also dramatically aid an individuals performance in most sports. A person that is in shape usually portrays a sense of control and enjoyment for their life that is envied by most. Anabolic steroids have been .....

.... from the impact scatter around the crater making a rim like structure. The northern hemisphere is very low compared to the southern hemisphere. In the north the ground level rarely reaches above one km below the datum. This stark contrast between north and south is thought to have happened 3 Gyr ago. The south was continuously bombarded with meteors. The north would get hit but it would erode or volcanic flows would cover it. The north also has evidence of ancient stream channels and at the extreme north and south glaciers are still present in the form of an ice cap. Tharsis: The region known as Tharsis is at the .....

.... surface area which enhances the productivity of respiration. The inner membrane and outer membrane effectively divide the mitochondria into two internal compartments. The space located between the outer and inner mitochondrial membrane is called the intermembrane space. The space enclosed by the inner membrane is called the mitochondrial matrix. It is here that many of the metabolic steps of cellular respiration occur. The intermembrane space reflects the solute composition of the cytosol, because the outer membrane is permeable to small solute molecules. it has its own small group of enzymes, because the o outer membrane is .....

.... subtle ways. The inherent properties of wood have always made it attractive as a versatile resource but there are other, more subtle ways in which it affects people. The tropical rainforests, responsible for producing most of the earth's breathable air, have been given the lofty title of "lungs of the Earth," and as stated by the Canadian Encyclopedia Plus '93, "forests provide an additional, although intangible, benefit: the opportunity for renewal of the human spirit" (CAN ENCYC). Once humanity accepts these facts, we open ourselves up to profound responsibilities regarding their protection. Unfortunately for both ourselv .....

.... are drawn with the aid of a keyboard, mouse, or tracking ball. One selects the starting point of a line, the ending point, and the line is drawn. A scale at the bottom of the screen tells how long the line will be. On some CADD systems, the computer itself can measure how long the line will be while the operator inputs the length of the line. Lines are the basis of all drawings. Straight lines are fairly simple and quick to make, but what about curved or wavy lines? That's what different CADD commands are made for. Different CADD commands make different things on the screen possible. There are commands for dimensionin .....

.... gone into identifying the sources of acid rain and the damage that it causes. As research continued, the situation reached catastrophe proportions in the late 1970's. By this time, thousands of lakes in Canada and Scandinavia had been declared dead, devoid of life, while emissions of acid gasses continued to rise. Acid Rain Chemistry As mentioned earlier, the term acid rain is used to describe a variety of different types of acidic deposition. These include "wet" deposition such as rain, snow and fog, as well as "dry" deposition in the form of acidic gases and dust. The term acid rain is only used to describe deposition which is m .....

.... is required. The product is known as smog. The notorious brownish color of smog is due to nitrogen dioxide of the mixture. Increased temperature stimulate the reaction, which is why ozone conditions are worse in the summer. It is an oxidant, meaning it takes electrons away from other molecules, and disrupts key structures in cells by starting chain reactions. Ozone is a serious national problem. Half of the largest urban areas in the United States exceed the ozone standards. The worst regions in the US include California and the Texas Gulf coast, and the northeast and the Chicago- Milwaukee area during the summer. The o .....

.... merely the start of a new beginning. After all the leaves have fallen, and the ground is littered in seas of immense color, the very structure that carried the leaves remains-the trees. They live on long after the leaves have fallen and died and remind us that no matter how long, cold, and terrible the winter is a new spring will come. Even though loved ones die and leave the earth behind the memory of them still remains planted firmly in the soul of the family. Eventually after the winter of pain and sorrow is over a new realization occurs that they have gone on to a better place and that they will see them again. Following the co .....

.... of electrons involved in the formation of (a) sodium chloride and (b) calcium fluoride. Each atom forms an ion with an outer shell containing eight electrons. For many elements, compounds cannot be formed by the production of ions, since the energy released in the formation of the lattice of ions would be insufficient to overcome the energy required to form the ions would be insufficient to overcome the energy required to form the ions in the first place. In order for the atoms to achieve a noble gas configuration they must use another method of bonding by the process of electron sharing. From figure 2, you can see that th .....

.... words, summarize difficult concepts, and often utilize attractive visual aids. Authors strive to communicate issues to audiences of varying levels of education. In order to accomplish this effectively, authors adapt their work in a format that expresses their concepts to audiences in pragmatic fashion. However, a disadvantage is that these adaptations can lead to misinterpretations of information. Attached is a newspaper article I obtained through the web but was printed in the "Discoveries" section of The Dallas Morning News on September 14, 1998. It was written by Karin Jegalian and it focuses on cloning and its biologi .....
