A Chromosome Study Lab An examination of the chromosomes of a cell under high magnification can give much information about an organism. Figure 1 shows the chromosomes of a somatic cell as they might appear in an organism if enlarged many times their natural size. A somatic cell is any cell making up the organism except for reproductive cells. In this investigation‚ it is expected that you: a. learn what a chromosome Karyotype is. b. prepare a Karyotype of chromosomes according to the instructions

Michael A. Joyner English 112 25 0ctober 2014 The Atomic Bombings Were Necessary To the dismay of many people on August 6‚ 1945‚ the first atomic bomb was used in the history of mankind as a part of warfare. Many people died as a result of these bombings in Hiroshima and Nagasaki‚ and because of the bombings‚ Japan knew it had been defeated‚ so it soon afterwards surrendered to America. I believe that the bombings were necessary in order to make Japan surrender because Harry Truman‚ the President

comes to the topic of animal testing‚ most of us will readily agree that it is a debatable topic. Where this argument usually ends‚ however‚ is on the conversation if animal testing is necessary. Whereas some are convinced that using animals for testing has contributed to many lifesaving cures and treatments‚ others maintain that these animals are very different from humans and‚ therefore‚ make poor test subjects. My own view is these animals have produced many treatments‚ but not outcomes that are

Electoral Votes Are They Necessary Someone asked the question what is an Electoral College‚ what does it mean and how does it work.

Gun Control and Why it is Necessary What does it take to maintain a proper and orderly society? This question is not easily answered. There are numerous statements that can answer that question. One answer that some people may use is “Gun Control: Securing the use‚ sale and purchase of firearms in a society so that the murder and violence rates decrease.” There are different extremes of the gun control issue. There are those who say that ALL firearms should be registered by ALL owners or that

which eukaryotic organisms produce egg and sperm having half the genetic information (haploid) of the other cells in the organism’s body (diploid). You will notice some similarities to mitosis but some definite differences in meiosis that result in genetic diversity in the gametes as well as the offspring formed by the eventual fusion of the egg and sperm. Two of the most noted differences in meiosis are that 1) there are two complete divisions resulting in four daughter cells and‚ 2) meiosis has

they are rarely used in self-defense. More gun control is necessary because people are killed by guns very often. Private Citizens shouldn’t have handguns because they don’t serve any military purpose. A common person shouldn’t have their hand on a gun unless they’re serving the country or state. Guns cause violence‚ which is why there are so many mass killings. Not everyone has to be armed to feel safe. More gun control laws are necessary and need to be stricter for the protection of women.

“Eukaryotic chromosomes are generally much bigger than those of prokaryotes. In eukaryotic cells‚ replication may begin at dozens or even hundreds of places on the DNA molecule‚ proceeding in both directions until each chromosome is completely copied. Although a number of proteins check DNA for chemical damage or base pair mismatches prior to replication‚ the system is not foolproof. Damaged regions of DNA are sometimes replicated‚ resulting in changes to DNA base sequences that may alter certain
