Paragraph 1 Topic Sentence: “Racism is the false belief that people are divided into a hierarchy of races, with certain groups inherently superior to others by virtue of genetic inheritance.” •Prejudice or animosity against people who belong to other races •Racism is the belief that race accounts for differences in human character or ability and that a particular race is superior to others •The belief that people of different races have different qualities and abilities, and that some races are inherently superior or inferior •Racial stereotypes and jealousy are sometimes the cause of racism Concluding Sentence: All in all, racism is the discrimination of individual people all throughout the world.
We also know that glaciers range from temperate valley glaciers to ice streams.
Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.He is credited to be the first scientist to suggest that the unstable carbon isotope called radiocarbon or carbon 14 might exist in living matter. Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. Libby who first measured radiocarbon’s rate of decay and established 5568 years ± 30 years as the half-life. Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating.
