  • Acid Rain - 999 words
    ... an affect the fish in the water in two ways: directly and indirectly. Sulfuric acid directly interferes with the fish's ability to take in salt, oxygen and nutrients crucial for daily life. Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is key in their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fishs gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissu ...

  • Animal Intelligence - 963 words
    Animal Intelligence? Often those who study animal intelligence are searching for the human reflection in the animal world. They feel that by unraveling the workings of the animal brain, they might find clues to the mysterious minds of humans. And because of their closeness to humankind, they find monkeys and apes especially fascinating. A major component of intelligence lies in flexibility of mind and adaptability to situations. When things change, when they are not the way they were before, the intelligent animal notices and tries to adjust to the changed circumstances. The instinctual animal, such as a honeybee collecting for the hive, sometimes cannot adjust, so it continues in its old be ...

  • Ants - 392 words
    Ants Ants are social insects that live in colonies being some of the most successful of insects. Ant colonies include one or more queens, workers, eggs, larvae and pupae. The worker ants maintain their developed structures known as "nests". Nests protect the ants against their enemies, some protection against extremes of weather, and are often placed close to water and food sources. Some ant species nest in the ground, many times under concrete or slabs. Some species will be found in wood such as fence posts, dead logs, and hollow trees or within structures. Ants are formed with a head, a thorax, or mid-section, and an abdomen connected to the thorax by a very short, narrow stalk. On their h ...

  • Biotin - 873 words
    Biotin Biotin is important for healthy hair and skin. 100 mg of biotin may prevent hair loss in some men. Biotin helps to relieve muscle pain. It promotes healthy nerve tissue, bone marrow and sweat glands. It also relieves seborrheic dermatitis in infants. Biotin works with folic acid and vitamin B12 to break down fats, protein, and carbohydrates. Biotin is found in most foods and also manufactured by bacteria in the intestinal tract. Most biotin deficiencies are associated with the consumption of raw egg whites which contain avidin. Avidin binds with biotin to prevent its absorption into the blood. Cooking the egg whites deactivates avidin. Biotin is non-toxic and probably not required in ...

  • Cats - 1,236 words
    Cats Many people today have pets for pleasure and companionship. Nearly any animal can be a pet, such as hamsters, rabbits, birds, fish, frogs, horses, and even cats and dogs. Besides being a loving companion, pets serve many other purposes as in protecting homes, destroying vermin, and providing a means of transportation. The elderly and the childless couples can rely on a pet as an emotional outlet. In addition, pets can be kept for their beauty, rarity, or for the beautiful sounds that birds can make. Today pets are usually purchased from breeders, pet shops, or animal shelters rather then individually captured and tamed. All pets were made domestic, including cats. Cats are the second mo ...

Pivorun Dolphins of the Amazon River: How Sotalia fluviatilis and Inia geoffrensis coexist in their habitat The Amazon River and its lush, beautiful forest are surely among the most amazing ecosystems in the world. The ever-present, primordial cacophony that echoed in my ears as I stood breathlessly watching saddle-backed tamarins (Saguinus fuscicollis) leap from tree to tree is what I will forever crave to hear again. As a biology student, I have always read about the great biodiversity of the neotropics, as the importance of hab ...

  • Finch In A Pinch - 752 words
    Finch In A Pinch Problem Statement As scientists, we have come to this island to observe the evolution of finches when forced into an unfamiliar habitat with a changing food supply. Hypothesis We believe our finch, Pherous robustus, will have a good chance at survival because its beak will allow for the finch to grasp many different seed shapes and sizes. Conclusion During our first 5 years, corn grew well on the island. Our finch population steadily increased during this time period. Our finch was very well adapted to eating the corn because it was very easy for our finch to pick up. During the next five years there was a drought and only block plants grew. Our finch population steadily dec ...

  • History Diagnosis And Treatment Of Equine Protozoal Myeloencephalitis - 1,575 words
    History Diagnosis And Treatment Of Equine Protozoal Myeloencephalitis HISTORY DIAGNOSIS AND TREATMENT OF EQUINE PROTOZOAL MYELOENCEPHALITIS. Equine Protozoal Myeloencepalitis is a serious neurological disease in horses caused by a parasite protozoa thought to be sarcosystis neurona. The disease was first identified in the 1960's when lesions and inflammation were seen in the brain and spinal cords of horses that had died of severe neurologic disease. Protozoa were discovered on the lesions in 1974, however the vector was unknown and the disease considered rare. Recently the opossum has been isolated as the probable vector and the likely parasite organism identified as Sarcosystis falcatula. ...

  • Hopewell Culture - 1,813 words
    Hopewell Culture Studied since the discovery of the conspicuous mounds in Ross County Ohio, the Hopewell have been an archaeological enigma to many. The tradition is so named for the owner of the farm, Captain Hopewell, where over thirty mounds were discovered. Earlier studies focused more on the exotic grave goods such as precious metals, freshwater pearls, many of these objects had come from all corners of the continent from the Rocky Mountains to the Gulf of Mexico, and north to the mid-Atlantic coastline (some say Hopewellian influence reached Nova Scotia). Earlier scholars of the Hopewell (1950s through 1960s) were well aware of the influence of the "Interaction Sphere", yet concluded t ...

  • Mariculture - 1,793 words
    Mariculture Mariculture As the Spanish entered the capital city of Tenochtitlan they were astounded at the many marvels of the city but one of the things that most caught the eyes of the foreigners was the extensive plant growth on the lake surrounding the city. These images were describe the among the first recorded descriptions of large scale mariculture. Mariculture, or aquaculture, refers to the rearing of the aquatic organisms under controlled or semicontrolled conditions. Although there is a simple difference between the two, aquaculture generally refers to the exploitation of freshwater fish and mariculture more generally refers to the culture and farming of marine organisms. Simply p ...

  • Native Americans - 1,251 words
    Native Americans Many times throughout history, specific events occur that explain why the existence of Native Americans are necessary for the Spanish and English colonists to survive. The Native Americans were like parents to the Spanish and English colonists. As a newborn baby is introduced to the new world, alike, the Spanish and English were introduced to a New World in which the Natives were already a part of. Their inhabitance of the land dates back to many thousands of years ago where they inhabited all regions of the Americas. When the Europeans arrived the Natives gave the colonists knowledge about the land. At times the Natives cared for them and supplied them with food and various ...

  • North Korea - 3,011 words
    North Korea The United States has been presented a dilemma towards its foreign policy with the Democratic Peoples Republic of Korea (North Korea). North Koreas alleged launch of a new Taepo-Dong I missile on August 31, 1998 has heightened American worries and escalated an already tense situation with North Korea. The United States response towards this new missile, which could possibly be able to reach the edges of both Alaska and Hawaii , will be a factor in its decision on whether or not to continue to finance support towards North Korea. New sanctions could mean the collapse of a weak North Korean economy. Already on the brink of economic and political collapse, the loss of U.S. and KEDO ...

  • Ozone Layer Poisoning - 1,099 words

The increase in radiation will start to diminish crops and other food sources. Starting with the depletion of the ozone layer, the domino effect of the extinction of biological systems on Earth would continue to plants and then on to the marine ecosystem. The effects of poisoning of the ozone layer will lash out on the marine ecosystem. The marine ecosystem would severely suffer from the thinning ozone and the increase exposure to ultrviolet radiation. Starting with phytoplankton, the foundation of acquatic food chains, would loose th ...

  • Primate Evolution - 1,720 words
    Primate Evolution Variation in the choices of food on a daily, seasonal, and yearly basis is one of the greatest differences between primate species. Primate diets have generally been divided into three main food categories-fruit, leaves and fauna (including insects, spiders, and bird's eggs for the most part). The different diets also are referred to as Frugivores, Folivores, and Insectivores (fruits, leaves and insects respectively). These gross dietary categories are correlated with aspects of primate activity patterns such as home range and group size. There are different problems that have to be overcome in order to obtain a balanced diet on a day-to-day basis. New leaves and mature lea ...

  • Samwise Gamgee - 1,154 words
    Samwise Gamgee What exactly is a rain forest, you say? Well, on the outside, a rain forest has a wall averaging 20 feet thick that is made of a tangle of vines that love light. This wall seals off the interior creating the illusion that the whole jungle is this thick. But if you find an animal path or stream to follow, you can slip through and enter this mysterious world. Once you're inside, you can look up and see a tree canopy that's as high as a 17 story building! And it's pretty dark too, a perpetual twilight. Only 1% of the sunlight ever actually touches the floor of the forest. And moonlight, even a full moon, doesn't get through at all. You'd better have a flashlight with you if you p ...

There are only two noticeable fluctuations on the entire island and one is the old limestone quarry that has been filled in, but still has depreciation in ground level. Types of Soils The heavy limestone buildup under the soil prevents the island from having mature soil. A layer of humus covers the limestone less than six to eight inches thick on the eastern side of the island, and considerably thicker getting up to two feet on the western side. (Moline 30). Vegetation differences cause the difference in thickness. The western side of the isla ...
