... years ago, toward the end of the Mesozoic, The Age of Reptiles . It was among the last of the dinosaur species evolve before the Cretaceous- Tertiary extinction 65 million years ago. BEHAVIOR: Triceratops was probably a herding animal, like the other Cartesians. This hypothesis is supported by the fining of bone beds, large deposits of bones of the same species in am area. Triceratops hatched from eggs, which may have been cared for by adults. Which threatened by predators, Triceratops probably changed into its enemy, like the modern-day rhinoceros does. This was probably a very effective defense. DIET, TEETH, ADN TRICERATOPS POSITION IN THE FOOD CHAI ...
... down by energetic light rays (UV-C radiation) in a reaction that liberates an atom of chlorine, which destroys ozone by oxidising with the Ozone molecules, forming Cl-O and Oxygen. One atom of chlorine can destroy 10,000 ozone molecules! Atoms containing bromine, nitrous oxide, and hydrogen oxide radicals are also primarily dangerous. As a result, the Ozone in the stratosphere has been reduced to such an extent that ozone holes are appearing around the globe, in particular one over Antarctica that in 1995 measured 8.2 million square miles. This depletion has allowed more dangerous UV-B radiation to reach the earths surface. So what effects will ozone depletion ...
... by over 20%.” All engineering jobs are paying well, proving that highly skilled labor is what employers want! “There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services,” says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. “The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the long run it is potentially self-destructive because there will not be enough purchasing power to grow the economy,” M. B. Zuckerman. My feeling is ...
... the original rock producing the Pedler gneiss and Old Rag granite which can be observed in the Shenandoah National Park. In late Precambrian time this super continent began to rift apart under the tensional forces producing the Catoctin rift basalts that can be observed in the Shenandoah. As they rifted apart, they created a growing ocean called the proto-Atlantic or Iapetus after the father of Atlas, for whom the Atlantic Ocean is named. Towards the end of the Precambrian, the tensional forces changed to compression and subduction began. Volcanic islands grew as a result of andesitic volcanism associated with the subduction. With continued subduction and conve ...
... clouds. A cirrus cloud appears in delicate, feather-like bands that are not attached to each other, and is usually white with no shading. Cirrocumulus clouds appear like very small round balls or flakes. The cirrocumulus clouds sometimes form a pattern of a buttermilk sky. The cirrostratus clouds sometimes form tangled webs or thin whitish sheets. A large ring or halo is sometimes seen around the sun or moon when the cirrostratus covers the sky. The middle layer of clouds range in altitude from 6,500 to 23,000 feet. The altocumulus, altostratus, and nimbostratus clouds are found in the middle division. The altocumulus clouds are more rounded and p ...
... the need for other drugs. Steroids though take a few hours to have an effect and therefore ineffective if needed for immediate relief. Other treatments include allergy shots and Antihistamines which can be used as a preventer of asthma. These reduce allergic reactions in patients and therefore reducing the chance for allergies to trigger inflammation in the asthmatic. Antihistamines however, cause drowsiness and should not be taken when driving or working at jobs where you must be alert. The medications that are discussed in the case study are bronchodilator inhalers (such as ventolin) and Cromolyn (Appendix 1). Bronchodilators are asthma relievers and there ...
... . The main chemicals in air pollution that creates are sulfur dioxide and nitrogen oxides. usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This forms a mild solution of sulfuric acid and nitric acid. Sunlight increases the rate of most of these reactions. Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to the earth as . Water moves through every living plant and animal, streams, lakes, and oceans in the hydrologic cycle. In that cycle, water evaporates from the land and sea into the atmosphere. Water in the atmosphere ...
... the atmosphere. Here are a few equations: 1. (2So2+O2 2So3 2) So3++120 H 2So4 The second reaction takes place very quickly. Therefore, the making of So3 in the damp atmosphere is assumed to be the lead to the formation of sulfuric acid. Phase two: the aqueous phase, sulfur dioxide occurs as three species. [S {iv}] [So2{aq}]+[+1S03-] +[So32-] This process occurs by a twofold process. 1) So2 (aq) H++H S o3- 2)H so3-(aq ) h++ So32- The establishment of the equilibrium is dependent upon such things as ph. , droplet size, "sticking coefficient" for So2 on water, etc. What was being done to prevent acid rain was the 1995 implementation of phase one of the c ...
... from the urethra, painful urination, or painful sex. ½ of all cases of pelvic inflammatory disease, which leads to an ectopic pregnancy in pregnant women, is caused by . Ectopic pregnancy is the leading cause of death of pregnant teens in the inner city and poor neighborhoods. also causes conjunctitis. This is a swelling of the eyes which can lead to blindness. The bacteria also can lead to pneumonia. Although it is the most easily treated STI, most people in danger won’t get checked until complications show, and that is why the disease is spread so much. It takes about three weeks for most people to see symptoms. In that time, they have sexual contac ...
... the “fight” or “flight” hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine. Mineralocorticoids steroids control the overall body fluid. Mineralocorticoids are critical to regulate concentrations of minerals in extracellular fluids. The major target of aldosterone is the distal tubule of the kid ...
