Potato Experiment Essay

The hypothesis that was tested in this experiment was that both strains of brewer’s yeast will grow better in fermentable sugars (sucrose) than in non-fermentable sugars (glycerol) because it is a better carbon source. The prediction for this experiment is that the fermentable sugar (sucrose) will cause the TRY 143 flo ↑ yeast to increase growth the greatest and the TRY 140 flo ↓ to increase in…

constructed by space aliens. Sagan believes there’s a dragon in his garage, but can’t explain if it’s actually there because he has no real evidence to show that there’s an actual dragon in his garage. He then experiments his theory, according to Sagan the dragon is invisible. In his experiment he spreads flour all over the floor to locate footprints but the dragon floats in the air. Next, he tries to detect the fire from the dragon with an infrared sensor, but the dragon produces heatless fire.…

dogs were removed were responsible for the discovery of insulin, which is important for the lives of diabetics (ProCon.org). Experimentation on chimpanzees is also responsible for a hepatitis B vaccine, and researchers are hopeful that similar experiments on chimps can yield a vaccine for hepatitis C (ProCon.org). Thalidomide, used for the treatment and prevention of a skin disease caused by leprosy, caused birth defects and death among infants. However, if tested on animals first, its…

acknowledges a counterargument to his argument. What is it? Wilson’s “nod” to his critics is best exemplified in the final paragraph of this article, in which Wilson points out that “Human behavior is complex, and it is not possible to conduct experiments to test all aspects of what people do or why. But there are entire disciplines dedicated to the experimental study of humans and they are tightly controlled and ethically acceptable ways.” Wilson is saying that the science of studying humans…

could have been achieved by the manipulation of the positive pairing rather than the actual liking of the DE100 logo itself. The DE100 experiment had a simple and straightforward design which would be easy to replicate. It is not time consuming, therefore, boredom is avoided for the participants and therefore, it is cost effective for the researcher. The experiment allowed for the replication of the Chen et al. study to appreciate that the manipulation of one thing (positive pairing) could have…

Tucker performed science in action by performing an experiment with skin tissue in order to determine the gene responsible for formation of the skin features. Example two relates to Lab #11, “Diversity and Adaptation”. “Skin organs” are relatively small features that allow organisms them to eat, survive, and…

I have also learned that it can get very complicated if safety measures are not taken. Planning ahead of time for extraneous variables, and possible mistakes is critical to attain accurate results. Also, because psychology is a social science, experiments do not work the same way in this area as they do in chemistry, which I have taken. In chemistry, the results are predictable, and controlled. In psychology, if we are measuring a…

most effective compliance techniques. Also, it is a huge manipulation tool for those who master and understand it. In the first study, there were six experimental conditions based on random assignments. There were only male participants in this experiment due to women being reluctant to comply…

books (Ariely). Ariely uses the concept of behavioral economics to help prove how decisions are made. He aims to answer: What influences our decisions? In the book, Predictably Irrational, Ariely explains how decisions are made very well by using experiments to support his thesis. Predictably Irrational examines the rationality of decisions people make on a day to day basis. Ariely explains that decisions are not what we would expect them to be, instead they are predictably irrational.…

Summarize: This article examines the effects of acute exercise on long-term memory. They assessed for memory by using a paragraph recall, in which participants listened to two paragraphs and then had to recall them 35 minutes later. Participants were randomly assigned to one of three groups: exercise prior to exposure, exercise after exposure, or no-exercise. The participants included 48 young adults recruited from the University of North Carolina-Greensboro campus. There were 15 men and 33…
