If Dr. Hayes’ believes his research is correct, why won’t he release his raw data for independent review? There was no difference in the effect of atrazine on both genders. For both genders, once the level was past 1 ppb, a steady decrease of size is noted, but when less than 1 ppb, a minimal increase is seen. In both trials, the data had the same pattern of size increase and decrease with the levels of atrazine despite the different levels, thus the experiment was repeatable. The effect of an exposure that is less than 1 ppb typically resulted in a small increase in size, but once the atrazine level was 1 ppb or greater, there was a steady decrease in the muscle’s size.
As we did not analyze a large area, which encompassed multiple biomes, we did not find the “s” shape graph, which is evident in figure 1 in the literature review. The gradual flattening of the graph is because species are not counted twice (when the area expands). The plots analyzed were also relatively homogenous and the species were fairly frequent. Hence, when the plot has been expanded enough (in this case to approximately 6 m2) most commonly occurring species have been found and counted. From then on, it is only the occasional infrequent species that is added to the number.
The darker mice have a mutated Mc1r gene because they present a darker coat from the light-colored coated mice. This happens because of a mutation in the Mc1r gene that increases the production of eumelanin by melanocytes that then results in a darker coat. This is alternative to the lighter-coat mice who have a lighter coat because their Mc1r gene goes through no mutation resulting in a presence of melanocytes which produce melanin and therefore decrease the production of
Erasmus Darwin mentioned that the color found on many animals were to help concealed themselves from a prey or to avoid some type of danger in which they may be found in. Nineteenth century naturalist such as Wallace main focus was finding out information on how an animal can blend in with its environment or surrounding objects in which an organism was found in. By the end of the ninetieth century an individual named Abbott Thayer main focus was to find out how many different types of camouflage existed. He also went into extend of wanting to know why having the camouflage ability is important and how some organisms may use it as sexual signaling. Abbott Thayer work he has done in the past in greatly influential since he had outstanding ideas on camouflage species.
Doing this disservice of non-white cultures ultimately becomes a problem as there are no real views of the world truly in pop culture. This exclusivity really becomes a problem in our society because white people are still seen as superior and this takes our country a step back in becoming an equal and diverse country. Even though this might not seem like a big deal, the
In addition, Brumfield’s low IQ scores, considering IQ tests margin of error, is enough to question his intellectual capacity as reasonable doubt and win his Atkins hearing. As far as the 5th Circuit claiming that the state court was not in violation of his rights because they initially did not provide him funds to make his case, is of no importance since the state court had acknowledged their mistake. After given the funds to show proper evidence Brumfield was indeed shown to be
Disaster could have been avoided if Victor had made an attempt to contain his work, instead of assuming that leaving an unpredictable being could have no negative outcomes. Victor’s blind pursuit of fame and ignorance was akin to that of Icarus, and his lack of forethought was akin to that of Jephthah. Considering all the evidence and comparisons, it is abundantly clear that it was not the pursuit of knowledge and fame that doomed Victor Frankenstein; but it was his divine ignorance and responsibility that had doomed
Overall, this experiment was not as effective because it was performed on adults, who are already set in their ways opposed to children that are more easily influenced. However this experiment did allow white individuals the opportunity to be discriminated against, which was something they had never experienced. Also, none of the people stood up for each other, which was one of the goals going into the experiment. Because of the results of the adult-aimed experiment, this should remain an experiment for children who have not yet formed their ideas and perceptions of
An example of a symbolic threat would be like not having the same values and beliefs. According to Stephan et al. based on the first study, “Neither the symbolic threat nor the realistic threat by themselves caused more negative attitudes than the control condition, but then realistic threats and symbolic threats were combined they did lead to more negative attitudes” (5-6). Most racial and ethnic groups do not have the same cultural values and beliefs. A good example that projects a clear image of both realistic and symbolic threats combined would the current immigration issue in the U.S. President Trump has persuaded enough people that undocumented immigrants are a threat for our socioeconomic standing.
DuBois also wanted it to be recognized that high unemployment among blacks was not because they were lazy it was because whites did not want to employ them. (PP. 241,242) Slide 6 Most contemporary sociologists agree with Weber’s view of ethnicity Most contemporary sociologists also favor DuBois’ position The reason why most contemporary sociologists will disregard Weber’s view of race is because most contemporary sociologists think we may even have a subjective perception of biological similarity. (P. 242) Slide 7 Historically race has mattered more to people than ethnicity did Ethnic groups face discrimination as well but they do not not experience it to the degree that race does Racial categories are basically given to people while ethnic groups are usually chosen by people for themselves (although it wasn’t always this way) (P. 242) Slide 8 The textbook mentions a lot that many different sociologists find that they see race and ethnicity overlap in many places which makes the differences between the two so hard to
The purpose of this study was to determine whether a relationship between implicit racial preferences and explicit racial attitudes/personal experiences exists. A weak positive correlation between the IAT and survey was predicted, due to previous studies’ positive correlations, but also due to the mitigating factor of the sensitive topic potentially yielding inaccurate survey responses. My results did not follow the previous studies’ findings, as there was no correlation between the IAT results and survey responses, but Greenwald et al.’s meta-analysis (2009) did caution that more sensitive topics would have less predictive validity. Baron et al. (2006) examined the relationship between implicit race preferences and explicit race attitudes at various ages (6, 10 and adulthood) to understand the origins of implicit racial preferences.
With further research I learned of gamatic isolation and preyzgotic barriers, which is the reason as to why simply put, differing species are just not able to create hybrid organisms of the two. The first barrier to hybrid and chimera creation is preyzgotic barriers, which limit the chances of different species from even coming into contact with one another. Prezygotic barriers can include factors such as differing mating rituals, and differing environments. However, if two species successfully manage to make contact with one another, gamatic isolation is the reason as to why the said egg and sperm cannot successfully combine, therefore making crossbreeding with certain species is simply
This means that the intervention did not produce evidence that the intervention is beneficial to decreasing my stress according to my definition. Statistical significance was achieved because the mean was below the standard deviation section, along with five data points. Since the study lacks clinical significance, yet shows statistical significance, the intervention is not realistic for me, even though it may be working and may simply be due to chance. Even though the intervention lacks clinical significance, I am happy with my results because it close to my
The reason to make this claim is that the researcher found that gases lighter than air (helium and nitrogen) had longer mean hang times and gases heavier than air had shorter mean hang times in Table 2 and because of the error bars in Graph 2, it showed significant differences between the means. This was reinforced with the results found in the ANOVA and Tukey test. Since all the p-values were less than 0.05, the results were also statistically different. These results differ from the works of other scientists. Other scientists have found that helium and other
Even polices that are grounded in theory often are not well supported or are difficult to implement. An example of this would be the scared straight program. While these visitation programs are extremely popular and have a logical appeal to the public there is little research to suggest that their support is justified. Scared straight programs focus on the severity rather than the swiftness or certainty of crime, therefore lacking two fundamental components of deterrence theory. Evaluation of scared straight programs has proven that they have no effective or actually harmful (Mears,
