C. Elegan Essay

Improved Essays
Throughout history, our understanding of neurological sciences has vastly improved alongside the examination and research of C. elegans. Through their ease of accessibility, C. elegans, have become a staple organism in discovering the mechanisms in which the nervous system promotes survival (Allen et al. 2015). The C. elegans’ structural integral is very straightforward, consisting of 302 neurons, with 60 of them being sensory neurons (Pieczynski 2016). Thanks to this simplicity, we can easily observe C. elegans’ reaction to various reactions to stimuli in order to observe changes in behavior. Furthermore, because the worms have many genes in common with humans, we can draw parallels towards the human brain and its neurological functions. Stimulation through olfaction is a specific way to observe the neurological behavior of C. elegans. C. …show more content…
elegans. In in a similar study, 2-nonanone has strong repellant properties toward C. elegans as their neurons detect chemicals that aren’t beneficial for them (Bargmann 2006). This shows that C. elegans use their olfactory senses to determine what they like and what they don’t like in order to compete for survival in their environment. Based on this evidence, the C. elegan is an exceptional model organism in studying neurological behavior, specifically on olfaction. A future study to be performed should be one in order to test the effects of a mixture of an attractive chemical and a repellant in order to see if the C. elegan would travel to the high-affinity attractant despite the possible danger of a repellant. Such an experiment would allow us to pursue the ways in which C. elegans may exhibit behavioral changes based on risk and reward systems. In conclusion, the chemical, 2-nonanone, proved to be an effective repellant towards C. elegans due plates 3 and 4 having a negative CI and previous research depicting the repellant chemosensation of

    This experiments purpose is to study the effects of manmade chemicals on daphnia. By observing 2-3 daphnia in 4 different environments I rated each Daphnia magna on a scale of 0 to 5 on how it affected their health. I averaged each of the daphnia’s heath based on their behavior and apperence. One pure water, then three other environments exposed to antifreeze, pesticides, and cigarette ash. After observing each environment for 30 minutes I discovered that cigarette ash is the most toxic to daphnia I rated their health at a 0 and antifreeze is the only chemical I tested that didn’t result in death I rated the daphnia exposed to antifreeze at a 2 due to the change in appearance and downfall of health .…

    The purpose of the lab was to observe the environmental impact on the behavior of pill bugs (Armadillidium vulgare) by using the steps of the scientific method. . We placed two pill bugs in an enclosed space and recorded the amount of time they spent in two categories of living spaces: hard rocks or soft sphagnum moss. Despite predicting that they would have a preference for a softer area, both pill bugs spent more of their time in the rocks than in the moss. This suggests that Armadillidium vulgare has a preference towards environments with hard surfaces over soft ones, possibly due to factors like light or surface area. However, certain experimental errors such as material density and poor handling may have skewed the accuracy of results.…

    The general argument made by author Michael Finnegan in his work, Republican Party disruption in Trump’s Nevada victory”, is that Donald Trump persuades his audience with his speeches and the cruel words he uses to get voters to vote for him in order to become President of the United States. More specifically, Finnegan argues that Trump has the necessary power to become the ruler of the United States. He writes quotes Trump when he stated, “We might not even need the two months, folks, to be honest.” This line reveal the confidence that Trump has for himself for winning the elections and Finnegan agrees with him when he stated “Trump might be right.”…

    While the goal of the goldfish lab was to teach the subject how to jump, this objective was unachieved, resulting in the inability to have our fish learn the trick. This outcome was most likely do to the minimal capacity in the brain of the goldfish, making it hard for the animal to remember how to perform the skill being taught. The fish only has a memory that lasts 3 seconds; however, the task took longer than 3 seconds to complete, resulting in the incapability of performing the jump. Also, the goldfish would not eat the food that was provided, influencing the failure of completing the trick because the fish would not interact with the incentive that was presented. In order to persuade the goldfish to complete the task, the food was going to be constantly raised higher until it located out of the water, in which the fish would have to jump and reach it.…

    Although Scott Russell Sanders and Gene Logsdon were taught lessons about life by completely different beings, the two writers write with similar aspects. In the essay, “Buckeye”, Scott Russell Sanders uses his experiences and lessons that he learned to describe his opinion of nature. His purpose resides in his fathers’ memory and the importance of the natural world. As for Gene Logsdon and his essay, “Lessons The Crick Taught Me,” he uses the “crick” from his childhood to explain his love and his connection with nature. Both authors are concerned with issues that such as where the source of primary learning comes from and the education with which they were raised.…

    1) Explain how the Lin et al. used the catFISH technique to determine which neurons are involved in particular behaviors (3 pts) Lin et al. used catFISH (cellular compartment analysis of temporal activity by fluorescent in situ hybridization) to compare the activation of c-fos expression during two successive episodes of behavior (either the same behavior or different) in the same animal. Through experimentation, researchers discovered that animals killed five minutes after fighting expressed only nuclear c-fos transcripts, while animals killed 35 minutes after fighting solely expressed cytoplasmic c-fos transcripts. Furthermore, after two consecutive behavioral episodes (of the same behavior), separated by 30 minutes, researchers discovered…
