.... problems in the world with humans and animals, it is hard to see this much money going to help just one whale. There are different types of animal stories that people hear about. There are the wonderful stories about adorable animals that do something amazing or need our help. There are also stories about animals that are used in good and bad experiments. When you hear about the treatment of some animals for research, you feel like forgetting about research. One such story was in 1988, three gray whales got stuck in freezing waters in Alaska, the whales were at risk of drowning because the holes in the ice that they were using to breathe were slowly freezing over. a large ....

.... the babies growth is slowed down. Carbon monoxide causes growing cells to be starved of oxygen, and effects the brain. This can lead to a low birth weight and higher chance of the baby dying at birth. Smoking is the single largest modifiable( changeable) risk factor in fetal growth retardation. Maternal smoking during pregnancy is also associated with genetic defects as well as an increased incidence of congenital malformations such as cleft palates, microcephalus, and clubfoot. Mothers who smoke one pack a day during pregnancy have an 85% increased risk of having a child with mental retardation. Mothers that smoke during their pregnancy have double the chance of having a ....

.... needed to run a computer, not just the kernel. Many people know of, or have at least heard of, UNIX. UNIX is both one of the oldest and one of the most powerful operating systems available today. "How can UNIX be old and yet powerful by today's standards”, you ask. The answer to this question lies in the history of UNIX; UNIX is a sort of subset of a much larger and more complex operating system called MULTICS. Both UNIX and MULTICS were developed decades ago for very large computers; only now, decades later are personal computers finally powerful enough to tackle these multitasking, multi-user systems with advanced features. Getting back to the crux of our ....

.... sphincter into the stomach. In the stomach, the muscular lining churns the food causing mechanical breakdown to take place. In the stomach lining, the pyloric glands secrete mucus that forms a mucus lining. Also in the stomach lining, are epithelial cells and the gastric glands. The gastric glands secrete gastric juices. Hydrochloric acid is released which deactivates the salivary amylase, in turn stopping the chemical breakdown of starch into maltose. Pepsinogen, which is an inactive enzyme, will change to pepsin, an active enzyme, when mixed with hydrochloric acid. Pepsin breaks down proteins, forming chains of amino acids called polypeptides. Chyme, a mixture of ....

.... acid and acetic anhydride, we obtain many disparate products. Not only do we get acetylferrocene, but we also get diacetylferrocene, some unreacted ferrocene reactant, and acetic acid as well. We will use thin layer chromatography (TLC), column chromatography (CG), and IR spectra analysis in order to determine the what proportions of each of these compounds will be present in the final product. Both TLC and CG are excellent methods of measuring the presence of a given substance. Both methods turn around a compounds polarity. As one recalls, polarity is a measure of the electronegativity of a compound determined by their placement in the periodic chart. Specif ....

.... (particularly changes caused by human activities) could cause the Earth's surface to warm up to a dangerous degree. Even a limited rise in average surface temperature might lead to at least partial melting of the polar ice caps and hence a major rise in sea level, along with other severe environmental agitation. An example of a runaway greenhouse effect is Earth's near-twin planetary neighbor Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered surface is hot enough to melt lead. Water vapor is an important "greenhouse" gas. It is a major reason why humid regions experience less cooling at night than do dry regions. However, variations in the atm ....

.... 1.5 billion cubic meters of [water] each year", (Gorrie 71). And while Canadians are for the most part are unaware of how much water they consume, they are even less aware of its presence around them. For water is an immense natural resource that rests not only around Canadians, but beneath their feet as well. In no region is this more pervasive than in the province of Ontario. Ontarians walk above groundwater supplies everyday, without the slightest notion of the extent to which they rely on this over-used and exploited natural resource. Canada as a whole "has far more water underground than on the surface - perhaps 65 times more than in surface lakes and streams",(Gor ....

.... injury before and after birth, as well as illicit substances. However, only inherited factors are generally accepted as significant causes. Evidence for such factors comes from every day experience: it is common to find families with several affected members. While such clustering'could also be due to shared non-inherited (environmental') factors,more convincing evidence has come from twin studies, as well as studies of ill individuals who were adopted away before the onset of illness. It is fair to say that even such studies do not suggest inherited factors as the sole causes. A more reasonable explanation is that there are individuals who have an inherited pron ....
