Worm Lab Report Essay Example

Worm Lab Report Paper The proper name for Blackmore is Luminous Variegates, they are freshwater worms most commonly found in North America ND Europe. The blood in Blackmore circulates from the dorsal blood vessel toward the head through a series of rhythmic contractions. A common pulse rate for the Blackmore is 7 to 8 pulse/minute. Hypothesis. If a stimulant increases heart rate, then when the Luminous Variegates is put into Nicotine its heart rate will increase. Materials and Methods: -First, fill a Petri dish with water and insert 15 blackthorns into the dish from the bucket containing all tot the Blackmore. Extract one worm into a pipette then insert into the capillary tube, Place the capillary tube under a microscope and adjust until the blood flow is seen. Pick one segment and count how many times it contracts during a minutes time, use the pipette and push the worm out of the capillary tube and into another Petri dish for the Petri dish which contains the worms that have already had their control pulse rate counted), Continue these steps doing one control and one nicotine test for each worm and make sure to count pulse rates from the same area of each worm that the data is as consistent as possible.

Take one form from the trash dish and insert into the Nicotine for one minute, make sure to measure how much water is getting into the Nicotine to know how much the solution is diluting. This was controlled so that we could make sure each worm was being put into the same strength nicotine solution. Take the worm and put it into a separate pipette and then another capillary tube and measure the pulse rate for one minute. Take the worm out and put it into the rehab Petri dish, a place for the worms to get their heart rates back to normal before joining all of the worms. Continue these steps and record the pulse rate once in the nicotine for each of the worms. Make sure to calculate both the mean and median from both the control and stimulant trials. Results: -The dependent variable is the pulse rate of the Blackmore in pulse/min. The independent variable is the nicotine added which is 2. Ml with ml H2O. The same IS worms were used in both trials ( each worm was tested once for each), the same Nicotine was used tort all stimulant trials, worms were in the Nicotine for the same amount of time, the pulse rate was recorded at the same time for ACH worm, same capillary tubes were used, same pipette was used, and worms were put into the same Petri dishes. Two trials were done with the Nicotine at ml and nine trials were done with 2. 5 ml Nicotine along with 1 ml H2O We had to dilute the solution because every worm in the 2. Ml Nicotine solution died. Spring water served as the positive control since it serves as the worms everyday habitat.

Free Essays on Oppression Of Women

Women’s Studies 2:30-3:45 MW The social construction of gender and feminist theories of oppression correlate simply because the social construction of gender is the basis for many feminist theories. Oppression is a socio-political system designed to purposely confine, shape, manipulate or reduce a particular class or caste of people solely on arbitrary grounds and for the advantage, of another class. Marlyn Frye states â€Å"a woman in an oppressive society is somehow like a bird in a cage.† Women are oppressed in many ways from issues of sexuality to harassment in the workplace. In one simple example neither sexually active nor nonsexual active women are in the right. A sexually active woman will be thought of as a whore, slut, or nasty. A nonsexual active woman will be thought of as green, unable to sustain a man, or lesbian. Either way the woman cannot win, it is one of the many double standards that women must face everyday. Firestone’s feminist theory argues that â€Å"Women are physically weakened by their reproductive biology and that the male dominated society arbitrarily takes advantage of this fact, and even makes that weakness more drastic.† I believe that this is quite true and that it is wrong to give gender roles. Gender roles are determined by specific biological differences in men and women, such as women are expected to do light weight house work because they are less masculine than a man, or men are taught to fight and be manly as described in â€Å"Learning to Fight†. Because of these gender roles in our society men are typically taught to dominate over women from birth to death and because of this women are unfairly oppressed. But where and why did these gender roles start? There are many explanations to those questions but few right answers. One common answer to that question lies in the bible, Genesis 3:16 â€Å"To the woman he said, I will greatly increase your pains in child bearing; with p...

Sadistic Killer and Rapist Charles Ng

Sadistic Killer and Rapist Charles Ng Charles Ng and Leonard Lake rented a remote cabin in the 1980s near Wilseyville, Calif., and built a bunker where they imprisoned women and used them as sex slaves, torturing and murdering them, their husbands, and children. When the spree ended, police connected Ng to 12 murders, but they suspected that the real number was closer to 25. Ngs Childhood Years Charles Chi-tat Ng was born in Hong Kong on Dec. 24, 1960, to Kenneth Ng and Oi Ping. He was the youngest of three children and the only boy. His parents were thrilled that their last child was a boy and showered him with attention. Kenneth was a strict disciplinarian and kept a sharp eye on his son, constantly reminding Charles that a good education was his ticket to success and happiness. But Charles was more interested in martial arts so he could follow in the footsteps of his hero, Bruce Lee. Charles attended parochial school, and Kenneth expected him to do all his assignments, study hard, and excel in his classes. But Charles was a lazy student and received low grades. Kenneth found his sons attitude unacceptable and got so angry that he beat him with a cane. Acting Out At 10, Ng became rebellious and destructive and was caught stealing. He disliked Western children and attacked them when their paths crossed. When he started a fire in a classroom while playing with off-limits chemicals, he was expelled. Kenneth sent him to boarding school in England, but he was soon expelled for stealing and shoplifting and sent back to Hong Kong. College in the U.S. lasted one semester, after which he was convicted of hit and run driving but, instead of paying restitution, lied on his enlistment application and joined the Marines. In 1981 he was jailed for stealing weapons but escaped before trial and fled to California, where he met Lake and Lakes wife, Claralyn Balazs. He lived with them until Ng and Lake were arrested by the FBI on weapons charges. Ng was convicted and sent to the penitentiary in Leavenworth, Kan., while Lake made bail and went into hiding at a remote cabin in Wilseyville in Californias Sierra Nevada Mountains. The Ghastly Crimes Begin After Ngs release from prison three years later, he reunited with Lake at the cabin and they began living out Lakes sadistic, murderous fantasies, killing at least seven men (including Lakes brother), three women, and two babies in 1984 and 1985. Authorities believe the number murdered is much higher. The spree ended when Ng and Lake were seen shoplifting a bench vise at a lumberyard to replace one they had broken torturing their victims. Ng fled; Lake was stopped in a car registered to one victim with the drivers license of another victim. He was arrested and, during a break in interrogation, committed suicide after writing down his and Ngs real names. Police continued investigating. They found the cabin in Wilseyville and gruesome evidence of the murders: charred body parts, corpses, bone chips, weapons, videotapes showing sexual abuse and rape, bloody lingerie, and a bed with restraints. They also found Lakes diary, which detailed acts of torture, rape, and murder he and Ng had performed in what he referred to as Operation Miranda, a fantasy that centered on the end of the world and Lakes desire for sexual slaves. Investigators also found a bunker built partially into a hillside with a room designed as a cell so whoever was in the room could be watched and heard from an outer room. Complete details of the tapes contents were never disclosed. A Long Legal Battle Ng was charged in the U.S. with 12 counts of murder. He was tracked from San Francisco to Chicago, Detroit, and finally Canada, where he was arrested for robbery and attempted murder committed in that country. After a trial he was imprisoned and, following a six-year, $6.6 million legal battle, was extradited to the U.S. in 1991. Ng and his lawyers used a variety of legal tactics to delay his trial, but it finally began in October 1998 Orange County, Calif. His defense team presented Ng as an unwilling participant in Lakes sadistic murder spree, but prosecutors introduced cartoons Ng had drawn depicting murder scenes in the Wilseyville cabin in details that a nonparticipant wouldnt have known. They also produced a witness who had been left for dead in the killing spree but survived. The witness said Ng, not Lake, had attempted to kill him. Fast Decision From the Jury After years of delays, tons of paperwork, and millions of dollars, Ngs trial ended with guilty verdicts in the murders of six men, three women, and two babies. The jury recommended the death penalty, and the judge imposed it. As of July 2018, Charles Ng was on death row in the California Department of Corrections and Rehabilitation, continuing to appeal his death sentence.

Political World Leaders of World War II Research Paper

Political World Leaders of World War II - Research Paper Example The paper tells that both leaders have left significant different memories, one of which is the unforgettable holocaust initiated by Fuhrer Adolf Hitler and a successful giant leap of economic redemption of Singapore from a Third World country to become another Asian Tiger country within the three decades of Lee Kuan Yew’s rule. Each leader delivered significant changes that they now deserve to be called great icons in the history of world leaders. Adolf Hitler who was the reason for the outbreak of World War II and Lee Kuan Yew who transformed Singapore from a Third World country to another Asian Tiger country, have been chosen and juxtaposed to learn the similarities and contrasts of their qualities and styles as leaders as well as how their reigns brought impact to the world.   Credited to Hitler’s achievements were as follows: â€Å"awarded the Iron Cross, First Class in December 1914†; â€Å"annexation of Austria and Sudetenland†; wrote the book â⠂¬ËœMein Kampf’ where it was an anti-Semitic, anti-Communist diatribe outlining his strategy for remaking Germany and becoming a conquering power throughout Europe†. â€Å"By 1938 Hitler had made Germany the most powerful and feared country in Europe (and perhaps in the world)†. â€Å"Majority of the German people supported him because they saw during his early leadership to his credit how unemployment virtually disappeared, the rising prosperity of the masses, the new social institutions and the increase of German prestige in the 1930’s.’s. All these achievements of Hitler were unparalleled in the histories of other modern totalitarian dictatorship† (Hitler, A. 2011). On the other hand, achievements credited to Yew include: redemption of Singapore from a Third World Country to become an Asian Tiger country now aligned with other rich Asian countries like Japan, Hongkong, and Taiwan. Singapore is now an envy of many neighboring Asian countrie s. Of Lee Kuan Yew’s outstanding achievements in redeeming Singapore, eradication of corruption was best recognized and envied by many ASEAN nations because ‘Corruption’ has alwaysbeen considered a systemic problem commonly found and associated with Third World nations (underdeveloped countries) including most Asian countries. Other Yew’s achievements include the substantial â€Å"increase in the living standards (Loh,K. 2011)† in this country: â€Å"As Prime Minister, Lee Kuan Yew presided over an exponential increase in Singapore's Gross Domestic Product (GDP) from US$704 million in 1960 to US$38 billion in 1990. This figure currently stands at US$222 billion, or over 300 times its level in 1960. Adjusting for cost of living differences, Singapore's GDP per capita was ranked 3rd

The Death of the Traveling Salesman Essay Example | Topics and Well Written Essays - 1250 words

The Death of the Traveling Salesman - Essay Example Sometimes the silence can be deafening; the song of the birds can be maddening. At times I find myself thinking of some other places, meeting other people, living another life. It would be nice to have another friend, just perhaps to have somebody to tell me about other places and things that are far beyond the woods that surround me. But then I thought, it won't be long and Sonny and I will have another one with us, and I quietly smile in anticipation. I brought out mother's old lamp outside to clean it. It was dusty and dull, but if I just give it a scrub, it would show, though not quite as clearly now, the beautiful lamp it once had been. Gently, as if in reverence to my mother's relic, I let the rag touch the lamp. At once, I was lost in reminiscence of all those wonderful times when this lamp shone in the center of our room. The many nights that we spent together sitting around it telling stories and laughing at jokes seemed to flood back to my memory as I began to push with more force into the crevices of the lamp. Ah, how I miss all of them - my family and our life in this very same house. I missed them all, but I could not shake the thought of wishing that someday, I'd be somewhere else. Half-smiling, I meticulously worked on cleaning my lamp while lost in reverie when, suddenly, a crash somewhere down below jolted me back to the present. I looked out and waI looked out and waited, my heart pounding like a thousand drums inside my chest. What could that be It sounded like a giant rock falling down the ravine, but it could have been something else. I remember hearing a whirring sound before the crash, something like a car, but cars never go this way. Was it possible that a car jumped of the ravine Were there people inside Are they hurt I found myself trembling, not just because I worried about people I never even knew, but also because I was excited that someone had wandered this way. I was scared to know what happened to them, while at the same time it scared me not to know anything about them. I was thinking what to do when I heard footsteps coming towards the house. There in front of me was a man, middle-aged and dressed too impeccably for somebody wandering through the woods. Immediately, I thought, this man survived falling down the ravine. "Good afternoon, madam," he said. I just looked at him in shock: I was shocked that somebody got out of the car before it fell, shocked that he was still able to gather his things, shocked at finding him there in front of me. Then there was something else: perhaps, I was too dumbfounded to have someone else here to break the silence for me. He began to talk about his car; he had an accident he was saying. "Sonny ain't here now, but he'll be home soon," I told him, "he can pull your car out of the ravine for you." My husband Sonny could do just about anything; he is my hero. "Are you okay" He didn't seem to hear my question. He was looking at me with glazed eyes, as if he was looking at me but not seeing me. He was detached, as if his mind was wandering perhaps in disbelief at how he had survived the accident. I do not blame him. "I am still sick" he goes on to tell me that he isn't well. Before he could finish, I open the door to let him in, not knowing why I trusted this man to come inside with me. Perhaps I pity him for what happened, perhaps because I was lonely and I wanted some company. Probably because I could see that, despite his

The Problem Of Domestic Violence :: Violence Against Women Essays

A problem has become known and to many, they feel that it's about time that the general public has taken notice. This problem has been a taboo for centuries and in the mid nineties it has chosen to let itself be known, the problem that I am talking about is domestic violence, it has ruined families, and demoralized the victims for years and now because of the "trial of the century" we finally are allowed to discuss it in detail, without fear of reprisal, now we get to familiarize ourselves with it and eventually after we get to know all about it we can, through treatment, get rid of it. In this paper, I will discuss problems with the so called epidemic of domestic violence. This entire paper will be about domestic violence, and because of that I feel it is important to note that "in most families men and women do not engage in physically abusive behavior" (The Brown U.), but because the media feels that it is their public duty to deceive us into believing that this problem is an "epidemic" (Domestic V.) we feel that, that is the case. Webster's dictionary defines epidemic as "a rapid spreading of a disease; to many people at the same time", this is not the case with domestic violence, one it didn't just happen overnight, it has just been popularized overnight, domestic violence has been going on from as far back as anyone can remember and probably farther than that, and two, this is not affecting many people at the same timem, because, as I've stated before, "in most families men and women do not engage in physically abusive behavior". If you as the reader gets anything out of this paper, it is important to me as the writer, that you find that, while domestic violence is a major problem for some families, it is by no means an epidemic. The major reason domestic violence has become so widespread over the last couple of years is because of the O. J. Simpson trial, as one person put it "the O. J. Simpson case would do for domestic violence what Anita Hill did for sexual harassment" (Domestic V.). The trial of the century brought a much needed attention to a issue that for too long was pushed to the back burner; domestic violence was a major issue in the case and it became evident, through the mass publicity of the case, that women weren't crying wolf all these years, because of "the murder of Nicole Brown ... the media would focus squarely on and

Hamlet Act 3 – the Dumb Show

The Dumb Show As Claudius asks for the ‘light’, he wants actual light. The light also means the act of asking for forgiveness. People who are of the same rank or are comfortable with each other speak to each other is pros. Hamlet speaking to the players, he speaks down to them in verse. For the play within a play, Shakespeare uses rhymed verse to elevate the language. This was done because Claudius was of a higher status and this raises the severity of the crime. Hamlet is using the language to identify the’ criminals’, through the language.Blank verse – an official occasion or speaking to someone older (like poetry), like Hamlet and his Mother. Hamlet tells Horatio that he admires his sense of loyalty, character and sincerity. In the Excerpt: Identify 3 metaphors, how the theme of appearance vs reality is revealed In what ways is Horatio similar to hamlet? In what ways is he a foil? Is Horatio expendable in the plays plot development? Is act 3 the c limax? No, I do believe that this was the climax. I believe iIs it evident that act 3 might be the climax of this play? This is because at this point we discover who Hamlet truly was. He is not the ideal hero we actually perceive him to be. His murder of Polonius was equal to the murder of King Hamlet. In both cases, there are children who lost their lives. Even though Claudius’s murder was pre-meditated, murder is still murder. Even though Hamlet did this without planning, the fact that he was able to take a life so abruptly shows that he is not in essence the ‘hero’ within the play.Anachronism – When something doesn’t fit the context of the play. For example Hamlet’s school didn’t exist in the time in which Shakespeare wrote the play. The recurring motif is son’s avenging their fathers. (Old Norway and Young Hamlet) Now Hamlet kills Polonius who has a son. Laertes After getting evidence that Claudius is actually guilt, he feel s that he can now kill Claudius. That is why he kills Polonius without confirming why it was. (Deduced that it was Claudius hiding)
