.... by commercial boats for the small amount of oil that can be extracted from their body. This oil is used to lubricate small parts in watches. Cheaper oils have been found, so dolphins are not hunted for this reason anymore. Dolphins can be caught in tuna nets by accident. Since dolphins have to breath at the surface they drown in tuna nets. It is estimated that 4.8 million dolphins were killed in tuna nets from 1959 to 1972. Under pressure from animal rights activists tuna consumers will not accept tuna from canners that do not protect dolphins. Animal rights .....

.... will improve efficiency or produce a greater yield. An acidic catalyst works due its acid nature. Catalysts are strong acids and readily give up hydrogen ions, or protons: H+. Protons can be released from hydrated ions, for example H3O+, but more commonly they are released from ionisable hydroxyl groups (R-OH) where the O-H bond is broken to produce R-O- and H+. When the reactant receives protons from an acid it undergoes a conformational change, (change in shape and configuration), and becomes a reactive intermediate. The intermediate can then either become .....

.... hunting. “The Black Rhino also has a long gestation period of 15 months with an interbirth interval of a single calf every 2.5 to 4 years, making it a slow process for rhinos to be introduced back into the world by birth” (International Rhino Foundation 3). “The Black Rhino is illegally hunted for its ivory horn that ranges between one foot to one foot eight inches long” (Speart 26). The animal is slaughtered for its horn while its carcass is left for the vultures. Since the Black Rhino was put on the list in the 1980s, conservation agencies have aided t .....

.... from the cell of its mother, and it had an exact genetic replica of its mother. This spurred arguments about cloning humans (Recer). After Wilmut hinted he may be repeating his experiment to silence the critics (Recer). Wilmut does not have the courage to repeat his experiment, also that the government will never allow him to repeate it. Another reason for cloning is that before it was done and even now scientists think cloning could help produce genetic models of human diseases. With this researchers could understand them and develop cures . Also cloning co .....

.... things to come. Two pharmaceutical companies, Sandoz and Ciba-Geigy, merged to create a new company, Novartis. The largest pharmaceutical merger in history, this new company is valued at over $100 billion. A near merger between Glaxo and SmithKline would have created the world’s third largest company, with a budget large enough to fund the estimated cost of sequencing the human genome. Its capitalization would have been larger than the annual gross national product of some 143 of the world’s nations (Enriquez 925). These mergers also allow the companies to .....

.... very helpful tool for cleaning our homes. The pacemaker is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are outside of the Earth's atmosphere. It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where there is no gravity and writing with pens would otherwise be impossible. They are convenient tools on Earth when we are trying to write on vertical surfaces. A zero-gravity training system is used to help astronauts become more comfortable with the c .....

.... self-induced ignorance and stifling conservatism. It's ironic that we have the opportunity to solve most of Canada's critical environmental issues in one fell swoop . . . with one simple plant. It is ignorance and the maintenance of the status quo that has blinded and crippled our ability to realize this resource. INTRODUCTION A plant exists that is so strong that it can be grown without requiring chemicals in almost every part of the world. Many have touted this plant as a possible way in which to wean society from its dependence on fossil fuels for energy .....

.... been dated between 4.5 million and 1.1 million years old. There has also been evidence that the australopithecus "man" lived in australia where fossils have also been found. The first discovery of an australopithecus fossil was made in 1924. The body of the australopithecus is smaller than humans, but biffer than chimpanzees. Also, The brain size of australopithecus is bigger than humans at about 475 cubic centimeters. This is also biffer than the chipanzees, but the brains were not developed in most areas. For example speech. The australopithecus species all .....
