Juror Eight In Twelve Angry Men By Reginald Rose - 776 Words
Picture a room with a large table in the center. There is a door, but it is locked. Filling up all the twelve seats around the table, there are twelve men: jurors debating the murder of a man living near the el tracks. The manââ¬â¢s son is his alleged killer, but one juror is not convinced. This image is from Twelve Angry Men, a play written by Reginald Rose. The Eighth Juror is being fair to the child, explaining how there are many ââ¬Å"what-ifsâ⬠in the situation. Juror Eight brings up many different pieces of evidence and logic to try to understand both sides of the case. He also wants the other jurors to see each side because he wants a fair trial. So, Juror Eight plays a very important part in this play. Juror Eight began the story byâ⬠¦show more contentâ⬠¦Instead of getting angry at the Sixth Juror immediately and saying hurtful things back, he continued with his argument politely. In summary, Juror Eight reveals many traits and characteristics of himself and these characteristics and his actions impact the story greatly. When the Eighth Juror tried to open the discussion and give the boy a fair trial, he created the whole story. The entire play would not have even occurred if not for the Eighth Juror. At the start, all of the jurors wanted to go home. Several even talk about how they want to ââ¬Å"get this over withâ⬠(Rose 7). So, all jurors were willing to vote as quickly as possible even if it meant that the defendant may not get the fairest hearing. But, the eighth was not willing to allow this because he wanted a fair trial. So, without the Eighth Juror, would there even be a story to tell? Most would think not. Juror Eight says many things that make the rest of the jury think a lot about. For instance, he states, ââ¬Å"Itââ¬â¢s not easy to identify a voiceâ⬠(Rose 32). By bringing up this valid reasoning, he added to the story and gave the boy a fair chance by questioning whether the story of everybody involved in t he case is definitely true. Furthermore, if the Eighth Juror had not promoted the discussion of this boyââ¬â¢s case, everyone would have voted guilty beyond reasonable doubt.

Persuasive Essay On Drunk Driving - 1114 Words
Each year, 13,000 people are killed by drunk drivers with a blood alcohol level above .08. Advocates of a new standard for in-car breathalyzers say that most, if not all, of those accidents could have been avoided if the drunk driver hadnt been able to turn his or her car on. If Congress and Mothers Against Drunk Driving get their way, could your next new car could come with a breathalyzer pre-installed? Much confusion surrounds in-car breathalyzer devices for those convicted of a DUI (driving under the influence) or DWI (driving while impaired), their nationwide rollout and several bills going through Congress on the matter. Some predict well all be driving a car with a similar device in future -- guilty or not -- whereas someâ⬠¦show more contentâ⬠¦Local, national advocates Carl McDonald, of MADD, is quick to point out that while the campaign group is in favor of mandatory interlock penalties in all cases of DUI or DWI, or for about 1.5 million Americans convicted each year; the group is not in favor of a rollout of breathalyzers in every new car. Some say that MADD is in favor of putting interlocks in every car, McDonald said. This is not the case. An interlock device is a method by which people demonstrate sobriety by actively doing something. We would never subject the population to that kind of thing by car. Thats only for offenders. Citing remarkable progress in the number of states signing into law mandatory interlocks for all offenders, he says the law is an easy sell to lawmakers -- even in the face of opposition from states rights groups. He adds that safety legislation on airbags and seat belts also became a federal issue and puts a timeframe of about ten years on a majority of states adopting, and enforcing, an interlock law for all offenders. What happens in real life...there are people who have been arrested and convicted of drunk driving, McDonald said. Following that conviction they were suspended.

In vial one, a wild type hyper female Drosophila and wild type mellow male Drosophila were crossed respectively to determine the dominant behavioural phenotype. The first reciprocal cross was then carried out in vial two to define whether or not the behavioural phenotype is x-linked recessive. According to the results obtained from vial one, when the wild type hyper female and wild type mellow male was crossed, the resulting offspringââ¬â¢s phenotypes were all wild type hyper. This cross shows that the hyper behavioral phenotype can be considered dominant in comparison to mellow. In the reciprocal cross, the behavioural phenotypes were isolated from one another while the wing veins were kept constant (in this case both wild type). When the wild type mellow female Drosophila and wild type hyper male Drosophila were crossed, all female offspring obtained a similar phenotype to that of the male parental while all the male offspring had phenotypical combinations similar to that of the female parent. We will write a custom essay sample on Biology Simulator Assignment or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This set of results shows that the mellow behavioral phenotype is a recessive x-linked gene carried by the female because the resulting male offspring showed the same characteristics to that of the female parent (received X ââ¬â chromosome from female parent). On an additional note, there was a higher frequency of females in comparison to men; 121 and 105 respectively. In addition, the behavioral gene is sex -linked also because of the different resulting phenotypical ratio in comparison to the cross carried out in vial one. Another cross was carried out in vial three to determine the dominant wing vein phenotype. A wild type hyper female and veinless hyper male were crossed and as a result, all male offspring consisted phenotypical characteristics similar to that of the female parent while the female offspring had the same characteristics to that of the male parent. The results from this cross are somewhat similar to that of the reciprocal cross carried out in vial one. All male offspring had features exactly alike to that of the female parent, thus showing that wild type gene is x-linked recessive as all male offspring were wild type and hyper. It is also important to note that in this cross, a higher population of males existed than females (112 hyper wild type and 104 veinless hyper respectively). The second reciprocal cross was carried out in vial four directly after the above cross. This cross displayed a concise picture of which behavioral and wing vein phenotypes were dominant. Unlike the cross the done above, this time, a veinless hyper female and wild type hyper male were crossed and the resulting male and female offspring were all veinless hyper. Thus, proving veinless and hyper behaviour are the respective dominant phenotypes among the female and male Drosophila. Another cross was carried out to derive the first filial generation in which a veinless hyper female was crossed with a wild type mellow male and as a result, the offspring were all veinless hyper (a total of 214 offspring) which can be seen on the cross ââ¬â record sheet under vial seven. A second filial generation was derived from a veinless hyper female and male Drosophila were crossed to distinguish a gene linkage relationship among the two phenotypes. Due to the genes being sex-linked, specifically x-linked recessive, the typical 9:3:3:1 ratio cannot be expected. However, a chi-squared test was carried out to determine how ââ¬Ëââ¬â¢offââ¬â¢ our values were from the expected critical value of 7. 815 (obtained at a p-value of 0. 05) since such a ratio was not expected. A chi value of 31. 1 was achieved which is greater than the critical value. Thus, the null hypothesis is rejected because the genes are linked which means that they are located very closely together on corresponding chromosomes. However, hypothetically, if a 9:3:3:1 ratio had been expected and if the chi value had been less than the critical value, than the null hypothesis would have been accepted as this indicates that the genes are not linked and are independently assorted (less cross overs /variation).
