Potato Experiment Essay

Introduction This experiment was conducted to measure the change in the Planarian’s speed according to different light frequencies. This experiment is relevant to a Planarian’s natural life as Planaria live in many different environments, and under several light variations. Planaria are found in both salt and fresh water, as well as amidst logs, soil, and a variety of plants (Conservation Commission of Missouri, 2015). This immense variety of environments corresponds with a variety of light…

1. It is necessary to list the experimental conditions when reporting a chromatogram because it will allow universal comparison. In the event that you want to compare your results with a colleague, the factors that can affect the results are listed and taken into consideration to get an accurate comparison. 2. The type of column used is listed, this column contains the stationary phase and the mobile phase is pumped through the column under pressure. The dimensions of the column are listed as…

“ring” like bells（1）, not all of them endless displays of wildflowers (2), change into different colors, sometimes appears as veins of brown and red throughout the rock, and how it forms are considered as the ringing rock’s four mystery natures from now and on. It was said ,Ringing Rocks Park that situated near the small Delaware River community of Upper Black Eddy possesses this “ringing” quality,was the largest boulder field in Pennsylvania . The ring human can hear is not the first sound, but…

Each member of the team recorded their own data which can be found in tables in Appendix A. When measuring, advantages and disadvantages when noted about each device. The small slide ruler was very precise, but the downfall was that it was too short to measure longer items. The ruler was convenient to use but its precision was limited by the lack of marking smaller the sixteenths of an inch. The tape measure allows for measuring very large objects while still proving to be very precise, but…

subsequently. Two experiments were conducted. In the first experiment, forty-five participants watched videos of traffic accidents, ranging from five to thirty seconds long. After watching each video, the subjects were asked questions about the accident, with the crucial question being “About how fast were the cars going when they hit each other?”, but different groups of participants were asked with different verbs, such as “smashed” and “bumped”. The results from this experiment indicate that…

patients. Laboratory strains of mice, however, are highly inbred, reared in artificial environments, and do not experience the same selective pressures as wild populations, such as the ability to forage and to elude predators. As a result, biomedical experiments conducted on laboratory strains may not be reflective of processes occurring in naturally reared mouse populations, and indeed, may not be reflective of what occurs in human patients. Open field tests are a standard method of assessing…

There were a total of 30 participants in the experiment. This was not a huge amount of participants, but it was enough for the researchers to maintain more control in the study. The participants were children (ages 7-11) and adolescents (ages 12-16) who were diagnosed with MDD at least 5 weeks prior this study in the NYS Psychiatric Institute in New York City. Before the study began, the researcher made sure the participants were not receiving any medications or therapy after being diagnosed to…

According to U.S labs, up to 100 million animals die each year due to animal experimentation in the lab? Animal experimentation is helping the understanding of diseases and new surgical techniques on both human and animals. Animal experimentation also helps the understanding of the correct medicine to use for any specific sickness they might have. Animal experimentations are very harmful the the animal body and is very cruel. Animals both small and large are taken away from their natural…

For our experiment, we will test SRT protein ligaments in a variety of conditions to determine the functionality and resilience of SRT protein ligaments relative to artificial and native human ligaments tested under the same conditions. The first test will examine the effects of the internal environment of the human body on SRT proteins. For this section of the experiment, we will place SRT ligaments in a solution analogous, in temperature and acidity, to the environment of the human body. The…

Introduction: Animal testing is a posing issue in our society. During this research project the question of “how should the issue of animal testing be addressed?” will be investigated. The reason as to why this question was picked is due to the amount of people that wear makeup that has been tested on animals, but are unaware of it. During this research assignment, the subheadings  What are the laws and regulation of animal testing?  What brands conduct the most amount of animal testing? …
