... a similar explanation as to why the is the most prolific of the invigorated species. Often s and many other invigorated species are referred to as "generalists." This has to do mainly with how and what they eat. In this respect, few other creatures have such catholic tastes or more ingenious methods of satisfying them as have s (Gilbert, 1991, p. 69). The list of what exactly the consumes is quite extensive. Eighty percent of their diet is rodents. However, they will eat pretty much whatever they can find. Watermelons are also a food source for this omnivorous and carnivorous species. As one of my sources puts it, the takes what it can get (Jones, 19 ...
... variey of sources Radiation: from the cosmic and radioactive isotope decays UV light: there were no protective ozone layer and thus immense heat. Electrical discharge from the never ending lightning caused chemical reactions to occur very often and there was also another source of heat from the young earth crust which was volcanically active. For most chemical reactions to take place, a spark of electricity is needed, and this was provided by the lightning in the atmosphere. Amino acids basically consist of hydrogen, nitrogen, oxygen and carbon. Due to all of the lightning chemical reactions took place between molecules of N2 and H2, thus these molecules formed ...
... such as glass or mica. Method We were set the task of investigating the factors that come into play when determining the resistance of a piece of wire. We would be provided with the necessary apparatus needed to carry out the investigations. The basic setup would involve a circuit with a set of cells connected in series with an ammeter and the piece of wire being investigated, and a voltmeter connected in parallel with the wire. The ammeter is placed in series with the wire. An ammeter has a low resistance, so that it introduces as little extra resistance as possible into the circuit. The voltmeter is connected in parallel with the wire. Voltmeters have a hi ...
... whatever is cool at the time. This usually means the biggest, meanest, least efficient car or the fanciest toys, generally leading to wasteful packaging and harmful chemicals or other bad stuff. “In short, Impact = Population * Affluence * Technology.” (Ehrlich, 1990) The problem is that everyone cares too much about societies image of them that they don’t think about the results of their actions. We also have a problem with the consumption of our resources. Many of the resources that we rely like fossil fuels, forests, and water are non-renewable. We are rapidly depleting these and have nothing to use when they are gone. Our society will have ...
... The membrane is essential to the survival of a cell due to its diverse range of functions. There are general functions common to all membranes such as control of permeability, and then there are specialised functions that depend upon the cell type, such as conveyance of an action potential in neurones. However, despite the diversity of function, the structure of membranes is remarkably similar. All membranes are composed of lipid, protein and carbohydrate, but it is the ratio of these components that varies. For example the protein component may be as high as 80% in Erythrocytes, and as low as 18% in myelinated neurones. Alternately, the lipid component may ...
... hours, they would have to close a gap of four thousand miles at an altitude of 245 miles while traveling at 17,500 miles per hour, only to have to move within three inches and two degrees of a quickly moving, very fragile object in space. One small thrust of a poorly aligned engine could cost one of four space-worthy shuttles and the world's first and only long-term space station. Docking was over with soon, and was followed by the cosmonauts of Mir greeting the astronauts of Atlantis. Gifts of flowers, candy and fruit were given by the Americans, who in return, following a Russian tradition, received gifts of bread and salt. Knowing the importance of the missio ...
... mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies include: reproductive disruption in starfish due to PCBs, bird eggshell thin ...
... arthritis, ulcers, hypertension, and diabetes. Also without research on animals we never would have been able to get drugs tested and approved for use. Animals help us to teach and practice new surgical techniques to doctors who perform today's delicate cardiac, ear, eye, pulmonary, brain surgeries, and other live saving surgery's. And most people faced with their death would rather live even if it meant killing animals. Next, animals help other animals as well. Veterinarians must learn the surgical techniques first so they can perfect their skills before they use them on other animals. Drugs for animals also use animal research to find cures for animal diseas ...
... area degenerates it leads to scarring or hardening ("Sclerosis") in the region. Over 5,000 Americans are diagnosed with ALS each year. There is great variation in the course of the disease. Symptoms usually appear in individuals between the ages of 40-70, though the disease has been reported in both younger and older persons. Survival after the confirming diagnosis is, on average, two to five years. Progression of ALS varies with each individual; therefore, some will live longer--up to 10 years, and about five percent will exceed 12 years. In some cases, the disease seems to plateau. Many patients are able to live productive and satisfying lives especially with ...
... people are eating considerably less than the average of 10 pounds per week. A world population of 10 to 11 billion by mid century will have an individual allocation of 6 to 7 pounds per week, equivalent to the diet of todays members of society living in poverty. Food projections are extremely uncertain since natural disasters are unpredictable and may increase if the forecasted effects of global warming materialize. Also, environmental degradation is increasing while water allocations are decreasing. Society will not be suddenly surprised by a “crisis point” at which food supplies are no longer adequate. Todays isolated anarchy and famine (which is politically ...
