Compare and Contrast an Alligator vs. Crocodile Essay

Compare and Contrast an Alligator vs. Crocodile - Essay Example Alligators are generally categorized as belonging to the alligatoridae family of crocodilians that is seen to also include the caimans. Perhaps on the most distinguishing characteristic aspects of the alligator is the fact that the noses of alligators are generally shaped to have a rather wide U-shaped, and rounded snout that can be deemed as having the appearance of a shovel (Barnes-Svarney and Svarney187-188). This broad design of an alligators snout can be perceived to have been designed mainly for strength and is designed to ensure that the animal can be able to easily withstand the stress to its bone structure caused when it applies massive force in cracking the rather hard shells of invertebrates such as turtles that form a significant part of its diet. As a result of an alligator’s upper jaw being significantly larger than its lower jaw, its jaws completely overlap when its mouth is closed with the teeth on the lower jaw becoming completely hidden as they neatly fit int o small depressions located in the upper jaw (Barnes-Svarney and Svarney187-188; Tan 40). This aspect can be seen to be especially pronounced in relation to the large fourth tooth of the animal located in the lower jaw. The salt glands situated on the tongues of alligators are less effective as compared to those of crocodiles and generally appear to have lost their innate ability of enabling the animal to excrete significant amounts of salt (Tan 40). Alligators can be able to grow and attain a length of about 14 to 16 feet a length that is considerably larger that of some crocodile species (Smith 205). With a V-shaped snout, the snout of a crocodile is basically found to be more pointed as compared to an alligator. The shape of its snout is seen to cause the animal to become more generalized and much better adapted for a wider range of prey. A crocodile’s upper and lower jaws are fundamentally the same width

Carbon based pollutants - Research Paper Example This paper will first focus on CO2 emissions discussing its negative impact on health. Then, the paper focusing on the government’s role in reducing CO2 emissions will discuss the Caps and Trade policy of the US government and the American New Clean Energy and Security Act. Among the various detrimental greenhouse gases, CO2 is the one that has the most virility. Although, on a molecule-for-molecule basis, methane is a more intense greenhouse gas than carbon dioxide, but as it is present only in small quantities, its effect is minimal when compared to CO2. (Schobert, 2002). CO2 levels have shown an uphill path due to rampant industrialization that started in the 19th century. With economics deciding the fate of a country as well as of an individual, Industrialization acted as a ‘catalyst’ for economics as well as environmental degradation. â€Å"Humans have been modifying the environment through processes associated with industrialization...One of the most important results of these activities has been increased emissions of carbon dioxide (CO2)† (Berliner, 2004). The common medical fact is humans have to exhale CO2, as high exposure of CO2 and build up of it in the human body will kill the person. However, CO2, emitted from the ind ustries as well as fuel based vehicles, are physically as well as mentally harming humans, other living beings and also the environment. The high exposure of CO2 will affect or injure the human’s organs including heart, lungs, etc causing many diseases like lung diseases, breathing problems, cancers and even death. The results of a study covering few heart patients from Boston showed that, carbon pollutants particularly from traffic exhausts was found to increase ST-segment depression, a condition in which there is a reduction in the hearts ability to conduct electricity. â€Å"When levels of black carbon and particulates in the air
