... muscles. They have torpedo-shaped bodies, which enable the animals to move through the water quickly and easily. There skin is rubbery and smooth. They have a layer of fat beneath there skin which keeps the dolphin warm and stores food. It is also think that the blubber helps them to stay afloat, since it as lighter then water. have distant cautious that make them direct the other whales, most dolphin species have a distinct beck where as porpoises have a more rounded shape to there head. They also have a hooked-shaped dorsal fin not fend in other specious, as will as conical teeth. Erans explains that evolved from the Mesonychicsi, large land mammals and the ...

... along the east coast of Australia. The reef is said to be 500,000 to 2,500,000 years old and is said to be visible from the moon. There is only one problem with this beautiful structure and that is the carelessness of man. Silt from deforested lands and pollution from crowded coastlines choke them, and overuse by coal miners, fisheries, and even tourists deplete and destroy reefs. There are many more factors which add to the destruction of the reefs, which if not stopped it will destroy all reefs. s are animals, not plants, sunlight is the key to their survival. They need it to power the millions of microscopic algae, called zooxanthellae, that live in th ...

... to the stripped-down eggs of Scottish blackface ewes” (Adler Par. 8). These nuclei had a full set of chromosomes, so fertilizing the eggs was not necessary. They then gave the eggs an electric shock to “initiate development” (Adler Par. 9). This was done after years of endless research. There was extensive research done in the area of embryo stem cells. Scientists have used such mouse stem cells for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site writes, “These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in ...

... spherical or disk shaped. are the most varied-shaped rocks of the sedimentary world. The way come to be is the mineral matter concentrates around the nucleus of a host rock. The nucleus is often organic such as a tooth or leaf or shell or fossil. As the mineral matter concentrates around the nucleus it forms harder zones known as nodules. are very odd in the sense that they very in size, shape, color and hardness. Often are mistaken for bones, fossils, meteorites and other odd objects. They can be so small that it requires a magnifying glass to be visible or as large as 10 feet in diameter and weigh hundreds of pounds. can also have somewhat of regular ...

... the way to Florida where my grandfather lived. It was a long trip to undergo, especially being six years old and knowing that my father never stopped the car. By the time we arrived at Fort Myers, it was a beautiful sunny day. The wind was gusting enough to pull my hair back, and I was admiring the palm trees, coconuts, and lizards near the Gulf of Mexico. The first few days were nice, but little did I know that I would soon be caught in the middle of a twister. I can clearly remember being in the car on a humid day with a little overcast. We were driving in the car when all of a sudden the wind started to pick up and it started raining a bit. Within five minutes, ...

... Mitosis has four sub-phases, prophase, metaphase, anaphase, and telophase. In prophase, the nucleoli disappears and the chromatin fibers become discrete chromosomes. The mitotic spindle also beings to form and the centrioles begin to move towards opposite ends of the cell. Also occurring later in prophase, the nuclear envelope fragments, and the microtubles attach to the kinetochores and overlap. In Metaphase, the chromosomes line up along the metaphase plate. The centromeres are all aligned and the sister chromatids straddle the metaphase plate. Anaphase beings when the sister chromatids are pulled away from each other. The chromosomess begin moving along t ...

... a permeability defect in the blood-air-barrier (the alveolar-capillary membrane); however, the precise mechanisms of toxicity remain an enigma. The U.S. produces over a billion pounds of phosgene (CG) per year for industrial uses; however, we do not stockpile this agent for military use. Perfluoroisobutylene (PFIB) is a toxic pyrolysis product of tetrafluoroethylene polymers encountered in military materiel (e.g., Teflon7, found in the interior of many military vehicles). The oxides of nitrogen (NOxs) are components of blast weapons or may be toxic decomposition products. Smokes, e.g., HC, contain toxic compounds that cause the same effects as phosgene does ...

... trouble with radio waves is that their long wavelength requires a large, cumbersome antenna to focus them into a narrow radar beam. The British showed that microwaves, with their short wavelength, could be focussed ina narrow beam with an antenna many times smaller. This enabled them to make more effective use of radar since an antenna could be carried on aircraft, ships and mobile ground stations. This characteristic of microwaves, the efficiency with which they are concentrated in a narrow beam, is one reason why they can be used in cooking. You can produce a high-powered microwave beam in a small oven, but you can't do the same with radio waves, which are ...

... around their teeth from hemorrhaging saliva glands and the sloughing off of their own tongues, throat lining, and wind pipe, crying tears of pure blood from hemorrhaging tear ducts and the disintegration of the eyeball lining and bleeding from every opening on the body. You see the blood spattered room and pools of black vomit, expelled during the epileptic convulsions that accompany the last stages of death. Their hearts have bled into themselves, heart muscles softened and hemorrhaging , the brain clogged with dead blood cells (sludging of the brain), the liver bulging and yellow with deep cracks and the spleen a single hard blood clot. Babies with blood ...

... The general opinions in the beginning are well- chosen considering the audience. Suzuki's tone is evident when he states "We have both a sense of the importance of the wilderness and space in our culture and an attitude that it is limitless and therefore we needn't worry." These words suggest that we are willing to reap the rewards of our vast resources but we fail to see the harm that we are doing, and will continue to do if we do not stop these actions. Although his approach for explaining his beliefs changes, Suzuki's tone of great concern remains consistent throughout the essay. After his views are presented, Suzuki begins to tell us what we have do ...
