In 1953, on the primitive ground, the 1st experimental demonstration for the evolution of complex molecules in a natural way from simpler components was discovered. In this experiment, Stanley Miller and Harold Urey took a mixture of the different materials like a "primordial soup" of water, ammonia (NH3), carbon dioxide (CO2) and methane (CH4) and then energized it by passing discharge of electricity through it (Chaisson, & McMillan 365). A few days after the experiment was done, they examined their mixture and discovered that the mixture contained lots of the amino acids that are similar to those that are nowadays found in every living thing on earth. Later on, scientific researchers successfully discovered nucleotide bases by performing a similar experiment.
The above figure shows the experimental settings of the Miller-Urey Experiment. Almost a week later, different complex molecules and amino acids were detected at the bottom of the trap, which reproduces the primordial mass within which heavy molecules were produced in the overlying atmosphere would have diminished (Chaisson, & McMillan 365).
There are many basic components in microspheres that are required in the formation of life but these microspheres are not living itself. Microspheres do not have the deoxyribonucleic acid (DNA) hereditary molecules. Despite the fact that no real life cell has been created yet from the beginning, most of the biochemists believe that the chemical evolution is the series of experiments most importantly from simple molecules that are not biological nearly to the life itself has been fully proved (Chaisson, & McMillan 365).
The figure above shows the chemical evolution. In this figure, a tiny drop similar to protein and rich of carbon shows the combination of many of the molecules of amino acid in a ...Download file to see next pagesRead More

Elevator Experiment
...the American culture (Lett, 2009) . I found myself in this Emic experience when I got onboard an elevator and would not face the front door and without talking to anyone or answering any questions. Mt experimentation was both participatory and observatory as I could clearly notice that the people in the elevator with me saw me as someone who was breaking basic rules of life. Reasons as to why Americans have rules regarding the riding of elevators are unstated. However these could be associated to the need to respect social existence. As much we are all individual beings and are entitled to personal and individual freedoms as to how we should behave and conduct ourselves (in a way that do...

Experiment or Quasi-Experiment
...1 Assignment 2 The hypothesis of my proposal is "Children who have high self-efficacy in softball are more likely to play baseball in a park district league." With this hypothesis, I am proposing the Nonequivalent Groups Design, or NEGD specifically for this experiment. This experiment intends to measure the amount of self-efficacy of the children towards playing softball. Moreover, it also intends to find out if those children that show high efficacy would like to play softball as a formal team or not. In this study therefore, the group that is used as a sample is intact and similar as the treatment and control groups. According to William M.K. Trochim, in this type of research design the most often...

Tuskegee experiment
.... The reason was that researchers were studying the effects of syphilis, which did not appear soon enough. So, they lingered on with the experiment for four decades. 4. Kantian ethics state that it is wrongful to conduct an experiment without taking informed consent from subjects. The experiment is also unethical if it has no social value. Hence, in Kantian terms, Tuskegee experiment was wrongful. 5. Nurse Evers was definitely to be blamed. She did not want the well being of her patients, since she was the one who always told them that they were being treated for bad blood only. She misinformed the patients and hid the...

Chemiluminiscence Experiment
...Chemiluminiscence Experiment Introduction Chemiluminescence is the process that leads to production of light energy froma chemical effect. Exothermic reactions produce quantities of heat which undergo conversion to light energy (Roda 50). The purpose of the experiment is to foster understanding of chemiluminescence to the learner by considering the concepts of exothermic reaction and emission of energy (Roda 51). The learner is to make recordings, inferences plus observations in the process and at the end of the experiment. Students will exhibit their understanding in the use of various lab apparatus such as beakers and thermometers. This undertaking...

Zimbardo's experiment
...abruptly in 6 days because the participants suffered psychologically. The more “powerful” prison guards became sadistic day by day while some of the “prisoners” suffered humiliation and torture each day and entered serious depression owing to the constant stress. The plight was shown clearly in the “Stanford Prison Experiment” video. 5. There are a few ethical concerns regarding this psychological experiment. Firstly, the participants were not informed about the experiment appreciably since Zimbardo himself was unaware how stressful the experiment could become hence the consent of the participants was not fully informed. The “prisoners”...

...Experiment Convenience number Experiment Convenience I choose cornflakes for this assignment. I take cornflakes every day before going to school and I think I have some kind of special relationship with this product. What is this products “hedonics”? Once I bought the product my expectations were very high. Cornflakes are packed in a way that is able to attract the consumer purchasing the product. The product seems to be so easy to prepare and highly nutritious. The aroma is excellent and has a sweet taste. The texture is very soft once you mix the cornflakes with milk. However, without mixing with milk the texture is rough. What benefits does it provide for...

Breaching Experiment
...by the notifications and that her friends were also annoyed, especially when comments that were made on her personal pictures that resulted in her friends being notified. She added that the researcher should “just go ahead, collect all the data required, and be done with it”. The response from the participant can best be described as irritated and confused, which made the researcher think about just how much Facebook has shifted in the past ten or so years from when notifications and comments were always welcome. Discussion The most interesting aspect of this experiment was just how much expected social norms on Facebook have changed since first...

Scientific experiment
...and beer production due to the fermentation process. The fermentation process involves the use of substrates in the absence of oxygen to produce energy. This has been used in the breweries and bread industries. In the sewerage treatment too there is the application. In addition, the process of aerobic respiration is important for biogas digester. In short, the application of aerobic respiration in the artificial and natural phenomena is wide and of greater impact. Experiment hypothesis Respiration is basic, essential process in the body of an organism. All organisms need energy for their survival in most cases the organisms acquire food...

...phenomena is wide and of greater impact. Experiment hypothesis Respiration is basic, essential process in the body of an organism. All organisms need energy for there survival in most cases the organisms acquire ther food substrates from other organisms which in turn is broken down to produce the energy. When these substrates are absent the organism will not be able to have effective respiration, this will inevitably result in the drailment of some processes which may pose dangerous effects on organisms. These effects emanates from the starvation by the organisms. Again this is mostly...

Miller-Urey Experiment
...of the carbon existent in the system they contrived in their experiment had turned to organic compounds (Willis, 2000). They also discovered that nearly 2 percent of the carbon now constituted 13 of the 22 amino acids that went into the making of proteins in living cells (Willis, 2000). Glycine was found to be the most abundant amino acid in this protein soup (Willis, 2000). No doubt the molecules produced in this experiment were simple biochemical compounds instead of being complete living cells or systems. However, the experiment conducted by Miller and Urey did establish that certain...
