Safety And Danger Of GM Food - Essay Example Using findings from studies that have been conducted and an analysis of the genetic makeup and the number of chromosomes of various organisms, this paper will establish facts about the concept of genetic mutations. It will examine and establish the facts behind the allegation that genetic engineering techniques are the reason behind the increased number of cancer cases globally. Cancer is caused by the existence and persistent growth of cells which are unregulated. It occurs where there is an unregulated growth of cells after cell division in a certain area of the body and the cancerous cells are capable of spreading to other parts of the body. The concept that genetically modified foods are carcinogenic is disputed because the predisposing factors to cancer are vast and their scope is not well understood by experts. Arguments for the case are for the opinion that the genetic composition of humans could be altered the same way that of plants is altered by the introduction of foreign genes thus causing the growth of cancerous cells. Even though there are scientists who see it as baseless, some have still gone ahead and conducted a number of experiments to determine the real effects of genetically modified foods have been conducted using rats. In this particular experiment, a group of rats is fed on a lifelong diet of some of the best selling genetically modified corn while the control experiment was fed with normal nongenetically modified meals. A report by Poulter, 2012, on the studies conducted showed that the rats that were fed with genetically modified corn developed tumors and some of their organs stopped functioning properly. 65 percent of them had developed tumors by the twenty-fourth month. On the other hand, the tumor rate of the rats that had been fed with normal food was at thirty percent (Poulter, web).

Crime mapping - Essay Example Clustering is indicated by the nearest neighbour index (NNI) and the NNI value from the table are 0.5746, 0.4679 and 0.4838 for shift 1, shift 2 and shift 3 respectively. An NNI value of 1 indicates random clustering and therefore the above NNI values are less than 1 and this indicates clustering of occurring offences. The P values for the three shifts is p value = 0.0001 and because this value is less than 0.05 then the clustering of occurring offences are statistically significant. From the table shift two has NNI value 0.4679 and a standard deviation distance value of 2887.5 and this is the lowest NNI value meaning that this shift is more clustered than all the other shifts, shift 1 has the highest NNI value of 0.5746 and a standard deviation distance value of 3039 meaning that this shift is less clustered. Shift three has a median NNI value of 0.4838 and a standard deviation distance value of 3104.7. Shift two has the lowest NNI value and this is an indication that given that shift two time is from16Hours to 24Hours there are less police officers and security agents available during this time of the day and therefore higher clustering of occurring offences. Shift one has a NNI value of 0.5746 which is statistically significant at 0.05 level of tests and this is the highest NNI value meaning that there is less clustering of occurring offences, this shift time is from 9 hours to 15 hours and during this time of the day more police officers and security agents are available and therefore less clustering of occurring offences. Shift three has a median value of NNI and this means that this shift has less clustering of occurring offences than shift two but higher clustering of occurring offences than shift one. This means that during shift three we have higher clustering of occurring offences than shift one but less clustering of occurring offences than shift two. From the above discussion it is evident that during the first shift which is from
