.... of the food chain. The warmer waters that are brought by these changing cycles hold less dissolved oxygen forcing fish to go deeper or venture elsewhere. Due to a lack of data during occurrences it is not fully known if fish populations are depleted solely due to exposure to . A decrease in their growth and reproductive success has been observed by many surveys in coastal waters. The link between climatic effects around the world and is now well established. It has taken many years of studying to understand how the pieces of the puzzle, from ocean currents to .....


Ebola
Number of pages: 4 | Number of words: 1060

.... cause disease in humans, while Reston only causes disease within monkeys. Filoviruses, arenaviruses, flaviruses, and bunyaviruses are the viruses responsible for causing viral hemorrhagic fevers.

These diseases usually progress until the patient becomes very ill with respiratory problems, severe bleeding, kidney malfunctions, and shock.

.... costs. The economics of a mine depends upon ore reserves, grade, type of ore, and the location. In order to mine, many months and millions of dollars have to spend in construction. There are only a few mines are discovered in convenient places, this costs a lot on transportation and labor on such an atmosphere. Construction includes food, health, accommodation and recreation facilities for the hundreds of working man.

Cloning 8
Number of pages: 5 | Number of words: 1212

.... are cut from a plant and placed in a flask with a nutrient medium. The cells grow and divide, forming embryonic tissues that are transferred to soil, where they produce complete plants. Grafting is another method of cloning used in Horticulture. Matching cuts are made in the stems of two plants, which are then fitted together so that their transport systems are in contact. The wounded area heals, and the two stems become a single physiological unit. All the McIntosh apple trees now in use and many other fruit varieties have been derived by grafting from single ancestral tre .....


Bacteria 2
Number of pages: 3 | Number of words: 608

.... mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic comp .....


Alzheimer’s Disease
Number of pages: 3 | Number of words: 739

.... found in the brains of Alzheimer's victims. They are found within the cell bodies of nerve cells in the cerebral cortex, and take on the structure of a paired helix. Other diseases that have "paired helixes" include Parkinson's disease, Down's syndrome, and Dementia Pugilistica. Scientists are not sure how the paired helixes are related in these very different diseases. Neuritic Plaques are patches of clumped material lying outside the bodies of nerve cells in the brain. They are mainly found in the cerebral cortex, but have also been seen in other areas of the brain. At the co .....


Hemp - Miricale Plant
Number of pages: 2 | Number of words: 362

.... far more and safer chemical compounds suitable for conversion to methane than any other plant. This renewable fuel contains no sulfur and while growing helps remove carbon dioxide from the atmosphere via photosynthesis. For thousands of years, all good paints and varnishes were made from an oil from the plant. Today, it has almost been totally replaced by chemically derived oils. In closing, it is estimated that if just 6 percent of all our farmable land were seeded with this plant, it could supply us with all our fuel, gas and oil needs. I find it funny that government offici .....
