Free Essays on Gonoreha

Gonorrhea Gonorrhea, also called â€Å"the clap,† is the most commonly reported sexually transmitted disease in the United States, with 1.5 million cases occurring per year. Ninety percent of infections occur in people under 30, with 15-19 year olds reporting the highest infection rates. Gonorrhea is caused by the bacteria Neisseria gonorrhoeae, which infects the mucus membrane of the urethra and genital tract. It can be spread through sexual contact and condoms provide protection against the disease but its not 100 percent effective. An infected woman who is pregnant may give the infection to her infant as the baby passes through the birth canal during delivery. Approximately eighty percent of women and ten percent of men with gonorrhea show no symptoms. If symptoms to occur the happen 2-8 days after transmission. Symptoms experienced by men include a painful urination and a fluid discharge. Women may experience a discharge, painful urination, bleeding, or lower abdominal pain. Ampicillin, amoxicillin, or some type of penicillin used to be recommended for the treatment of gonorrhea. Regardless of what drug is prescribed, it is important that the patient take the full course of medication and that he or she return to the doctor's office or clinic for follow-up. All sex partners of a person with gonorrhea should be tested and treated appropriately even if they do not have symptoms of infection. If gonorrhea is not treated, the bacteria can spread to the bloodstream and infect the joints, heart valves, or the brain. The most common consequence of gonorrhea, however, is PID, a serious infection of the female reproductive organs, that occurs in an estimated 1 million American women each year. PID can scar or damage cells lining the fallopian tubes, resulting in infertility in as many as 10 percent of women affected. Because gonorrhea is highly contagious and yet may cause no symptoms, all men and women who have sexual...

The Grassland Biome Habitat

The Grassland Biome Habitat The grassland biome includes terrestrial habitats that are dominated by grasses and have relatively few large trees or shrubs. There are three main types of grasslands- temperate grasslands, tropical grasslands (also known as savannas), and steppe grasslands. Sufficient Rainfall Most grasslands experience a dry season and a rainy season. During the dry season, grasslands can be susceptible to fires which often start as a result of lightning strikes. The annual rainfall in a grassland habitat is greater than the annual rainfall that occurs in desert habitats. Grasslands receive sufficient rainfall to support the growth of grasses and other plants, but not enough to support the growth of significant numbers of trees. The soils of grasslands also limit the vegetation structure that grows in them. In general, grassland soils are too shallow and dry to support tree growth. Variety of Wildlife Grasslands support a variety of wildlife including reptiles, mammals, amphibians, birds and many types of invertebrates. The dry grasslands of Africa are among the most ecologically diverse of all grasslands and support populations of animals such as giraffes, zebras, lions, hyenas, rhinoceroses, and elephants. The grasslands of Australia provide habitat for kangaroos, mice, snakes, and a variety of birds. The grasslands of North America and Europe support wolves, wild turkeys, coyotes, Canada geese, cranes, bison, bobcats, and eagles. Some common plant species that occur in North American grasslands include buffalo grass, asters, coneflowers, clover, goldenrods, and wild indigos. Key Characteristics The following are the key characteristics of the grassland biome: Vegetation structure that is dominated by grassesSemi-arid climateRainfall and soils not sufficient to support significant tree growthMost common at mid-latitudes and near the interiors of continentsGrasslands are often exploited for agricultural use Classification The grassland biome is classified within the following habitat hierarchy: Biomes of the World Grassland Biome The grassland biome is divided into the following habitats: Temperate grasslands - Temperate grasslands are habitats that are dominated by grasses and have lack trees and large shrubs. Temperate grasslands include tall-grass prairies which are wet and humid and short-grass prairies which are dry and experience hot summers and cold winters. The soil of temperate grasslands has an upper layer that is nutrient-rich. Seasonal droughts are often accompanied by fires that prevent trees and shrubs from growing.Tropical grasslands - Tropical grasslands are grasslands that are located near the equator. They have warmer, wetter climates than temperate grasslands and experience more pronounced seasonal droughts. Tropical grasslands are dominated by grasses but also have some scattered trees. The soil of tropical grasslands are very porous and drain rapidly. Tropical grasslands occur in Africa, India, Australia, Nepal, and South America.Steppe grasslands - Steppe grasslands are dry grasslands that border on semi-arid deserts. The grasses found in steppe grasslands is much shorter than that of temperate and tropical grasslands. Steppe grasslands lack trees except along the banks of rivers and streams. Animals of the Grassland Biome Some of the animals that inhabit the grassland biome include: African elephant (Loxodonta africana) - African elephants have a large head, large ears, and a long muscular trunk. The two front incisors of African elephants grow into large tusks that curve forward.Lions (Panthera leo) - Lions are the largest of all African cats. Lions inhabit the savannas of Africa and the Gir Forest in northwest India.Spotted hyena (Crocuta crocuta) - Spotted hyenas inhabit the grasslands, savannas, and semi-deserts of sub-Saharan Africa. Their population densities are highest in the Serengeti, a vast plains ecosystem that stretches from northern Tanzania to southwestern Kenya.American bison (Bison bison) - Millions of bison used to roam North Americas grasslands, boreal regions, and scrublands but the relentless slaughter of bison for meat, hides, and sport drove the species to the brink of extinction.
