Effect Of A Substance On Daphnia - 1285 Words

Abstract: The experiment was conducted by a number of individuals to see how the effects of a substance would have an effect on a Daphnia. The Daphnia’s were placed in multiple different substances environment to see the effect it would have on their heart rates. When doing the experiment the first step was to take the Daphnia and put it a Water solution to observe the heart rate of the Daphnia and record the heart rate. Recording of the heart rate were taken for when the Daphnia were in the Water solution that way they could compare with the next solution which was Caffeine. Caffeine was chosen because it raises the heartbeat of humans, so they wanted to see what would happen when given to a Daphnia. One drop of Caffeine was dropped onto the Daphnia and then observed to get a recording of the heart rate. The results for both of the solutions were different which arose the question of whether the Caffeine had an effect on the Daphnia’s. The control group was tested first with 5 trials of different Daphnia, this gave an average heart rate of 114.8 with a difference of 0 between the two Daphnia. The heart rates were recorded 3 times for each Daphnia, for each trial 2 Daphnia’s were tested. When the Daphnia were placed in the toxin the results showed a very obvious change in heart rate with an average of 15.6 in heart rates between the Daphnia placed in water and the Daphnia mixed with caffeine. The experiment was done in a controlled environment in the Parker build atShow MoreRelatedThe Normal Heart Rate Of A Daphnia Magna1552 Words   |  7 PagesIntroduction The purpose of this lab was to determine the normal heart rate of a Daphnia Magna and decipher the different effects that various substances had on it.

An Examination Of Paranoid Personality Disorder - 862 Words

An Examination of Paranoid Personality Disorder Introduction Paranoid personality disorder is a mental disorder that is classified as a â€Å"Class A† or â€Å"abnormal behavior.† This means that individuals with a paranoid personality disorder are overtly arrogant, mistrustful, suspicious of others, driven, industrious, and even successful in solitary careers, unromantic, typically high-minded and severely observant towards the external environment (Akhtar, 1990). The first descriptive case study of paranoid personality disorder began in 1893 when leading French psychiatrist Magnan distinguished paranoid psychoses into two types: chronic delusional state of systematic evolution and delusional states of the degenerates (Akhtar, 1990). He divided the latter category into three subtypes: paranoia associated with mental defect, chronic delusional states with a good long-term prognosis, and the delusional states of degeneracy (Akhtar, 1990). According to Magnan, the short-lasting, paranoid developments emanated from a constitutional degeneracy or a fragile personality that showed individual thinking, hypochondria, undue sensitivity, referential thinking, and suspiciousness (Akhtar, 1990). Thus, the reason I chose this topic because I knew a neighbor diagnosed with paranoid personality disorder. This tragic event happened during 1992 and in Atlanta, Ga.

Massive disappearance Free Essays

You awoke one day then you find that the world becomes suddenly empty of about 11 million Latinos that comprise at least the area of California. This is the controversial core premise behind the film â€Å"A Day Without a Mexican†. In essence, the film appears to highlight the idea of how America at least is dependent on the workings of this often-abused sector of the society. We will write a custom essay sample on Massive disappearance or any similar topic only for you Order Now Directed and co-written by Sergio Arau along with Yareli Arizmendi, the movie emphasizes the stereotyping of Latinos as Mexicans in California, and presumes all of these individuals are illegitimate immigrants. Moreover, the primary message that the film seeks to convey is that many individuals in the society take for granted the contributions brought both by legal and illegal Latino immigrants who work for these people. The range of the contributions of these Latinos covers most—if not all—of the essential endeavors in the society. From being a fruit harvester to being elite executives in a renowned place like California, Latinos play a huge role in the performance of the nation’s economy. This is one of the significant messages underlying the movie which is based on a brief film of the same director. The content of the movie can be summarized in the idea that an unexplained event covers California. That is, people within the state cannot communicate with individuals residing outside California. This is coupled with the disappearance of all the Latinos which heightens the chaos that surrounds the people. Particularly in California, the film depicts the central idea that nobody in the place likes or appreciates Latinos. This feeling is overturned by the sudden events in the movie, specifically the part which shows the disappearance of the Latinos. What the film is essentially attempting to establish is this idea: that, perhaps, the only way for everybody to realize the social worth and individual importance of these Latinos is to make them feel their absence in the society. That way, the disappearance of the Latinos will force these people to do the usual things and important social roles by themselves—which is why Latinos are an important segment of California. The movie narrates this plot by portraying the lives of four individual characters, all of whom share an integral part in their respective professions. A teacher as well as a common housewife, Mary Jo Quintana shares the same effect of the wide disappearance of Latinos with Senator Abercrombie, Louis McClaire, and Lila Rodriguez. In general, the massive disappearance opens up their once-private lives. As experts bring up various theories in an attempt to explain the disappearance of the Latinos, the status of the entirety of California starts to decline. The events led to the depreciation in the cleanliness of the state as garbage mounts in the streets of California and in the economic devastation of the state. This in particular sums up the idea that, indeed, Latinos have an important role in the continuance and progress not only of California but of America as a whole.

Essay about Missing Persons The Media Bias to Report Only Pretty Blonde Girls Essay Example For Students

Essay about Missing Persons: The Media Bias to Report Only Pretty Blonde Girls Essay A constant sight on the news or internet is of a missing person. Studies by the crimelibrary say that over 800,000 people go missing every year (4). Of those, a little over half are men, half are ethnic minorities and around 50,000 are adults. For such democratic statistics, one would imagine that there would be an equal amount of media coverage for these demographics, yet that is not true. If we observe carefully, we can see that the media tends to follow a certain pattern with who they pick to report on. Usually they are young, pretty blonde girls. At the very least they are likely to be women. Going by what we see, it would be a fair assumption to say that most individuals who go missing are female, youth or Caucasian, yet the statistics speak otherwise. Currently there is a long-standing debate dealing with the effects of media. Some believe that the media is just something to indulge or watch and that it has no significant affect on people while others say that has a powerful pull on society as a whole. Research indicates that bias in media articles leads to minorities and women being portrayed in a stereotypical or harsh manner (Hazell and Clarke 3). This leads to African Americans being seen as individuals fit for â€Å"lower status occupations,† (Hazel and Clark 7). Black men were also seen as hostile, intimidating figures mainly working as athletes or musicians while women were portrayed as domineering, overly expressive people (Hazel and Clark 9). Research also suggests that the media is a major decider in what crime cases get chosen to air on the news. While it was previously thought that what went on the news was arbitrarily picked or based on the most interesting cases, it turns out that it is not quite the case. J. .
