... Page 378.) Animal rights advocates and activists generally have ethical objections regarding treatment of animals during experimentation, but the use of animals in research for the benefit of all people is and always will be justifiable. Over 99 percent of all animal experiments are on rats and mice developed expressly for laboratory use. "Less than 1 percent of experiments involve cats, dogs, farm animals, nonhuman primates, frogs, fish, and birds." ( ŻEncyclopedia of Medicine, AMA®, "Animal Experimentation", Page 110.) Animal rights advocates try to sway public opinion by showing grotesque pictures of destroyed cats, dogs, farm animals, dolphins, and monk ...

... absence of water in the environment affects the surface area to volume ratios in plants. It is observed that plants in moist environments have more lush, larger foliage, while plants inhabiting desert conditions are generally smaller and have less photosynthetic surface areas. Hypothesis: Alternative Hypothesis: states the hypothesis being tested in this experiment. Photosynthetic structures of plants adapted to arid environments have a lower surface area to volume ratio than plants adapted to less dry or moist environments. Null hypothesis: there are no differences between the wet and dry habitat plants and observed differences are purely a result of chan ...

... systems are very important to a mineralogists and geologists; specification of the system is necessary in the description of each crystal system. Isometric This system comprises crystals with three axes, all perpendicular to one another and all have equal length. Tetragonal This system comprises crystals with three axes, all perpendicular to one another; but only two are equal in length. Orthorhombic This system comprises crystals with three mutually perpendicular axes, all of different lengths. Monoclinic This system comprises crystals with three axes, all unequal in length, two o which are not perpendicular to another, but both of which are perpe ...

... Some people have been known to be as young as 13years of age. Most colon polyps are benign but some become cancerous. Most FAP patients develop cancer by the age of 39. Another form of hereditary cancer is Hereditary Non-Polyposis (HNPCC). HNPCC accounts for five to ten percent of all cases. HNPCC develops also at a young age but not as young as FAP patients. The actual cancer appears in the persons 40's. HNPCC is known as a "fast growing" form of cancer. Along with colon cancer HNPCC patients are also at a much higher risk for other forms of cancer. Page 2 The causative factors of these cancers are not known at this time. Many doctors, scientists, and me ...

... first example of man performing corrupt experiments is genetic engineering. In this case, man alters the genes of the fetus. This might be acceptable if the reason for the alteration is a life or death situation. If the baby will not be able to live without the procedure being done, then it is acceptable. But nowadays, doctors are performing genetic engineering to pre-determine the baby’s sex. If parents are now allowed to choose the sex of their child, who can say where to stop? Every parent would want their child to be the "perfect" child. How the child looks, how it thinks, and anything else would be the parents choice and that is not their decision. It ...

For example, it is estimated that the food supply would reduce by forty to fifty percent without the use of on our crops. The FDA, EPA, and the Department of Agriculture try to ensure that the use of is necessary to the extent in which they actually are used by performing studies and proposing bills and laws to Congress. There is no dispute that are harmful. The purpose of is to kill certain fungi, plants, and even animals, so it seems only natural that they would have some ...

... predators. Wald noted that research is ongoing in growing agricultural products directly in the laboratory using genetically engineered bacteria. Genetically engineered animals are being developed as living factories for the production of pharmaceuticals and as sources of organs for transplantation into humans in the United States and abroad. Fish are being genetically engineered to grow larger and at a faster rate. According to U.S. News and World Report, many pharmaceutical drugs, including insulin, are already genetically engineered in the laboratory. Many enzymes used in the food industry, including rennet used in cheese production, are also available in ...

... can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of acid rain. Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will increase the acidicy of already acidic rocks and soil, such as granite, or the soil which results from corroded granite. Acidic chemicals, and alkaline chemicals react to each other by reducing the alkalinity or acidicy of each other. Which ever has the strongest pH level, usually will neutralize or reduce the p ...

... Consequently, a single ounce of gold can be drawn into a wire five miles long. Gold's malleability is also unparalleled. It can be shaped or extended into extraordinarily thin sheets. For example, one ounce of gold can be hammered into a 100 square foot sheet. Gold is the most reflective and least absorptive material of infrared (or heat) energy. High purity gold reflects up to 99% of infrared rays. Gold is also an excellent conductor of thermal energy or heat. Since many electronic processes create heat, gold is necessary to transfer heat away from delicate instruments. Gold alloy is the most tenacious and long-performing material available for protection of the ...

... area. Haphazard clear cutting of forests, while it maybe what Meadows would like us to think, does not happen. With every industry, every aspect is carefully debated and analyzed for the short and long term outcomes. Any industry that capitalizes on earth's resources figuratively signs a pact with the earth. This pact bonds this industry to the earth and requires that any harvesting of resources is not done so with haste and waste. There is a symbiotic relationship between the two. For the industry to exist there must be a constant supply of the resource. Without a constant supply the industry dies. Now, many people believe that the logging industry's obj ...
