cavity is one of the most frequently reported extra-hepatic disease associated with HCV infection. It has been suggested as a possible triggering factor for precancerous and cancerous oral lesions. Evidences suggesting a strong correlation with oral lichen planus (OLP), which can have a potential for malignant transformation and many epidemiological studies indicated a significant correlation with OSCC (Carrozzo and Scally, 2014). The first study conducted by Nagao et al., 1995, suggested a…

two or three miles wide and is made up mainly of three types of silver-firs. Muir describes this area as the simplest and best defined of the three zones. The highest zone is the alpine zone which is made up of dwarf pines, heathworts, sedges, and lichens. The pines grow up to an approximate elevation of 9,500 feet.…

If a tornado powerful enough happened and depleted the soil, a pioneer plant like lichen would begin to grow after a very long recovery period. Then, soil would begin to form and plants would start to grow again. Lastly, after hundreds or thousands of years, the soil would be back and animals would return to the tundra. A major problem…

process and why it is important to keep the traditions going many years to come. The tools needed were such things as brain hooks, oil jar, funnel, and embalmer’s knife. Some of the materials needed for mummification were things like linen, sawdust, lichen, beeswax, resin, natron, onion, Nile mud, linen pads, and frankincense. Some of the tools are thing we still used today in preparing the remains of a body. (###############) The steps in preparing the corpse is very important first the body…

Also known as Gray Ghosts, Caribou, are only found in limited numbers in the contiguous United States. Most of them are found in the deep forests of Idaho, near the border of Canada. Caribou have a high risk of becoming extinct, they could be found on the top of the list of most endangered species. Predation is one of the most reasons why caribou are facing endangerment. Caribou fall victims to predators such as wolves and cougars. Biologists have tried to create plans to prevent more caribou…

was massive production of black sooty smoke from furnaces that were used to burn coal. When the smoke was released into the atmosphere via chimneys, it coated surrounding buildings with a dark, black surface. Also the soot hindered the production of lichen in trees thus killing it and making the bark of trees darker than usual. When the dark colored moths landed on the trees and buildings, birds could not spot them to eat them therefore they became more popular and with time they reproduced…

Squamous Cell Carcinoma Squamous cell carcinoma is a common form of skin cancer. It begins in the squamous cells in the outer layer of the skin (epidermis). It occurs most often in parts of the body that are frequently exposed to the sun, such as the face, lips, neck, arms, legs, and hands. However, this condition can occur anywhere on the body, including the inside of the mouth, sites of long-term (chronic) scarring, and the anus. If treated soon enough, squamous cell carcinoma rarely spreads…

Vancouver is a coastal city in B.C. It has a population growth of 4.4%. This change had affected Vancouver because they now have more pollution and deforestation. Once Vancouver got more people the demand for vehicles has increased and the demand of other resources has increased as well. Since more people are using vehicles the pollution has increased there. It didn’t affect vancouver that much but, the increase has been a concern to the government. They decided to lower hybrid cars to help stop…

Industrial Melanism of Biston Betularia or the Peppered Moth in England has been a textbook example of natural selection since it was first noticed. Before the industrial revolution the peppered moth was most commonly found in the light colored Typica variety. During the industrial revolution there was a significant rise in the dark Carbonaria form and a slight rise in the intermediate Insularia form. Beginning in 1970 the Typica variety has been rising in frequency again. Carbonaria went from…

Alaska’s tundra support numerous avian migratory species during all four seasons, providing a breeding, rearing, staging, refugee and overwintering habitat. Some mammalian species that live in the Alaskan tundra are; muskox, caribou, foxes, wolves, lemmings and raptors. Some of the animals, such as the caribou, depend on tundra vegetation to survive the year. Foxes are dependent on the polar bear for the majority of its meals. For example, as soon as a polar bear is done consuming a seal, the…
