... two nipples. The female koala gives birth after a 20-35 day gestation period. When the joey (baby koala) is born, it is no longer than 2 cm and weighs no more than a 1/2 gram. The joey stays in its mother's pouch for 5-7 months. The term "joey² is used when you are talking about a baby marsupial. The mother gives "pap² to the joey, a liquid from the caecum (which is similar to the human organ, appendix.) This is thought to give the joey the ability to eat only eucalyptus leaves. When the joey emerges from the pouch, it clings to its mother for another seven months. The joey stays with its mother for another three or four years, until it is fully grown. D ...
... not necessary. They then gave the eggs an electric shock to “initiate development” (Adler Par. 9). This was done after years of endless research. There was extensive research done in the area of embryo stem cells. Scientists have used such mouse stem cells for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site writes, “These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body” (Par. 3). This is where genes can be altered and clones can be made. It has been a hard task locating and being able to work ...
... tangles and plaques were responsible for the women’s dementia. Alzheimer’s disease is a disorder marked by a gradual decline in brain function that gets worse with time. It used to be assumed that this change was a normal part of aging that we called senility. Some people develop this condition when they are as young as 40 years of age. However, the disease is most common in persons over the age of 65. It is estimated that approximately 10 percent of persons over 65 years of age may have Alzheimer’s disease and that in persons over the age of 85, up to 50 percent may be affected. Alzheimer’s disease is not a normal part of the aging process. It ...
... survivorship, reproduction and growth. Between critical winters of 1981-1982 the experimental grid area lost 77% of its population as compared to 79% and 96% loss for the control grids. Determining the survival rates, the authors used mark-recapture techniques, it was found that probabilities for survivorship in experimental grid (0.79+0.10) were similar to that of control grids (0.71+0.07; 0.56+0.07). Results yielded that extra food intake and cover provided from branches may have not been helpful in increasing survivorship. No differences were measured in reproduction of percentage in adult females caught lactating between control and experimental grids. Based on ...
... the “fight” or “flight” hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine. Mineralocorticoids steroids control the overall body fluid. Mineralocorticoids are critical to regulate concentrations of minerals in extracellular fluids. The major target of aldosterone is the distal tubule of the kid ...
... of malaria all over the world. It nearly wiped out the disease in some countries altogether. It has been repeatedly proven that DDT does not cause any form of cancer in humans. Contrary to what environmentalist attacks on the pesticide have alleged, the benefits of DDT far exceed the flaws. DDT was first synthesized in 1887 and patented as an insecticide in 1939 by a Swiss chemist, Dr. Paul Müller (Whelan 69). It initially became popular because of its effectiveness against insects, specifically clothes moths and parasites of both animals and plants. DDT was welcomed as a substitute for toxic insecticides like arsenic, mercury, fluorine, and lead (Whela ...
... one of several different nitrogenous bases linked to the opposite end of the deoxyribose. DNA has two specific functions: to provide foe protein synthesis, and hence the growth and development of the organism and to furnish all descendants with protein-synthesis and hence the growth and development of the organism. So all living things on plant Earth contains the genetic material DNA and the structure of a DNA molecule or combination of DNA molecules determines the shape, form, and function of the offspring. 2)The term "genetic technology"(or genetic engineering) is the modification of the genetic properties of an organism by the use of recombinant DNA technology ...
... this, however, is that the entire digital effects and animation industry is still in its infancy. The future looks bright. How It Was In the beginning, computer graphics were as cumbersome and as hard to control as dinosaurs must have been in their own time. Like dinosaurs, the hardware systems, or muscles, of early computer graphics were huge and ungainly. The machines often filled entire buildings. Also like dinosaurs, the software programs or brains of computer graphics were hopelessly underdeveloped. Fortunately for the visual arts, the evolution of both brains and brawn of computer graphics did not take eons to develop. It has, instead, taken onl ...
... in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine Monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use. Approximately 95% of the body's creatine supply is found in the skeletal muscles. The remaining 5% are scattered throughout the rest of the body, with the highest concentrations in the ...
... sea-surface temperatures in the eastern tropical Pacific rise above normal. In normal, non-El Nino conditions, the trade winds blow towards the west across the tropical Pacific. These winds pile up warm water in the west Pacific, so that the sea surface is about 1/2 meter higher at Indonesia than at Ecuador. The sea surface temperature is about 8 degrees C higher in the west, with cool termperatures off South America, dut to an upwelling of cold water from deeper levels. This cold water is nutrient-rich, supporting high levels of primary productivity, diverse marine ecosystems, and major fisheries. Rainfall is found in rising air over the warmest water, and t ...
