... Perhaps it’s the way that Hollywood uses a mix of fact and fiction in the series. This may have frightened many people into hating the Great White for it’s ferocity. It might have also been the size of the shark in the movie that’s kept thousands of people off the beaches and out of the water. Better yet, it could have been the overall storyline: A Great White shark with an eating disorder and a taste for human flesh. Perhaps that’s what is keeping vacationers from grabbing their trousers and snorkels. Over all, there have been 1026 attacks on humans by sharks in the last ten years. Only 294 of these attacks have been linked to Great White sharks ...
... just a ball of molten material. Since then, parts of the Earth have cooled forming the solid crust-mantle. This process has been occurring for roughly about 3.8 billion years. The mantle is about 2900 km. thick, which lies above a layer of molten magma that still exists today. The immense heat from the magma (approximately 2700(C) causes convection in the mantle (Figure 1). Convection is caused by non-uniform temperature in a fluid and density differences. This continuous convection is the cause of plate movement. Each complete cycle, called a convection cell, drives the plate in the direction of the cell. How does a 'solid' mantle move? The mantle may be ...
... second toe bore a 5 in hook -shaped, retractable claw that must have been a formidable offensive weapon. Deinonychus is known from fossil remains found in south central Montana during the 1960’s. It was a carnivorous, bird-like creature with characteristics similar to that of a Velociraptor ( one of the stars from Jurassic Park ). This fearsome beast was quite a ravage hunter. The Deinonychus attacked its larger prey in packs and often were successful in doing so because of their menacing claw. By hunting in groups, members of the Deinonychus pack have brought down dinosaurs much lager than themselves. Proof of this occurrence has been found today due the dis ...
... alliances we find ourselves locked into a self-induced ignorance and stifling conservatism. It's ironic that we have the opportunity to solve most of Canada's critical environmental issues in one fell swoop . . . with one simple plant. It is ignorance and the maintenance of the status quo that has blinded and crippled our ability to realize this resource. INTRODUCTION A plant exists that is so strong that it can be grown without requiring chemicals in almost every part of the world. Many have touted this plant as a possible way in which to wean society from its dependence on fossil fuels for energy and the need to log forests for pulp, paper and wood. ...
... hemophilia A. Hemophilia A's blood lacks the clotting factor eight. The rest of the 85% have Christmas, which lacks clotting factor nine. An extremely small number of hemophiliacs lack yet another kind of clotting factor. Both A and B forms have also been called the royal disease. Hemophilia was inherited by decedents of England's Queen Victoria and introduced into the royal houses of Spain, Germany, and Russia. Hemophilia A and B are caused by genes that are sex linked and recessive. A defective gene on the X chromosome, one of the two chromosomes, that determine a person's sex. The Y chromosomes which has no genes for clotting is the other chromosome. Male ...
... main absorption and digestion. The pH in the stomach returns to normal and the stretch receptor stop getting stimulated. #2 You are having severe stomach cramps, the doctor says that you secretin receptors have been blocked. How has this affected your digestive process and what two hormones might be able to alleviate one of the affects. Secretion inhibits stomach movement, emptying, slows secretion of gastric juices and causes bicarbonate to be dumped in from the pancreas and liver to the small intestine. This neutralizes the acid that is coming in. Since this process does not occur there is an increase of emptying of chyme into the small intestine. The small inte ...
... story. One clue is that patients have excess amounts of sodium and chloride in their sweat making it vey salty . At the University of North Carolina researchers found that salt imbalance caues thick mucus to accumulate in the patients lungd. High level of salt in lung cells draw water out of the mucus causing it to thicken.The level of salt in a cell is determained by the movement of ions across the cell membrane.Ions are carried across call memebranes by protein channels embedded in the cell membrane. Since the stucture and functions of proteins are determained by genes problems with ion transport can be assumed to have a genetic basis. In 1989 an American Cana ...
... and interesting shapes. At night the sky becomes enchanting and glorious. When the stars are out the sky is undeniably exquisite. The skys deep shades range from blue at dawn to deep oranges and purple at dusk. The sky scenes are genuinely picturesque. The forest changes it scenery in seasons instead of day and night like the sky. In the summer the forest is filled with majestic shades of green. The fall brings colorful shades of oranges, reds, and yellows. The winter deprives the forest of its colorful splendor, but brings a different type of beauty all together. In the spring all of the green magnificence returns. The forest is breathtaking anytime ...
... in the 1970's in a set aside special national park under full protection. Politicans and bureaucrats seem to be obsessed with numbers and not trends. Let me illustrate this with tigers. There are frequently requests as to the exact number of tigers, or a tiger subspecies left in the world. That tells you that there are people that care. But there are so little tigers left that we can not even keep track of them. We should look at the trend that the population is taking, rather than the number as a slice in time. Just as you might say of a young member of the Hunt family, that they were very wealthy. A hypothetical individual was 24 years old and had $1,000,000. ...
... large that we no not even a boundary, I sincerely doubt that the human race is the only form of life. It seems certain scientists have come up with other hypotheses concerning UFO's. While all astronomers yearn for a concrete explanation on UFO's, their beliefs on their origin contrast. Many looking for a more scientific definition disregard UFO's as nothing more than a mere misinterpretation of a plane, weather balloon, or meteor. Some have gone so far as to say that specific witnesses to UFO's have seen nothing more than a hallucination and "wanted" to see a UFO so their minds adapted that idea into an illusion to satisfy the urge. Personally, I have had tw ...
