Worm Pulsation Case Study

341 Words2 Pages

1. Worm Pulsation a) According to the hypothetical data depressants like alcohol have little influence on pulsations rate. Depressants slightly decreased the worms’ pulsation during the experiment. Stimulants like caffeine and ginseng had a much more significant influence on pulsation rate. Stimulants increased the worms’ pulsation rate during the experiment. b) After the comparison of data, I found that the mean pulsation rate for the worms suspended in alcohol was slightly lower than the pulsation rate of the same worm before contact with the drug. After contact with the alcohol the mean change of pulsation rate ranged from -2 to 2, with the average result being 0. These shows use that that alcohol did decrease some of the worms’ pulsation

    From the data obtained in Tables 1-3, we were able to plot multiple graphs using excel. These graphs give a better representation of the data as seen in Figures 1-9. It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes.

    Daphnia Magna are small crustaceans that are excellent for observing the effect of depressants on their nervous system. The purpose of this specific experiment is to observe the effect of ethanol, aspirin, and caffeine on daphnia’s heart rate. Not only do these chemicals affect heart rate, but they also affect the frequency of reproduction, number of eggs produced, and body structure. Pesticides similar to these chemicals can be released into the environment and daphnia re useful in monitoring toxicity levels. The agents being tested in this experiment can be administered to determine the effects of hormones, stimulants, antidepressants, and neurotransmitters.

    In this experiment, Pill bugs were exposed to different environments within a closed space and observed to determine which environment they preferred. The four different environments tested consisted of flowers, dirt, grass, and an empty space. Ten pill bugs were placed within the shoe box and observed for a total of 15 minutes to determine what environment the bugs preferred. The independent variables were the different conditions in each section of the shoe box, while the dependent variable was the behavior the pill bugs displayed. Throughout the experiment, the control variable was the empty section of the shoe box.

    The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants.

If the stimuli were detected the manatee would press a paddle if not it would remain still (Gaspard et al. 2013). While establishing the tactogram lips were not flared concluding the BLHs were used to sense the hydrodynamic stimuli (Gaspard et al. 2013).

    Nonetheless, besides fish, many other kinds of poikilothermic animals, such as snakes and frogs, use lungs instead of gills to breathe, and further researches may be conducted to explore if caffeine has an effect on their metabolism. For example, forty northern leopard frogs with similar body size will be captured and divided into twenty trials, and each two frogs will be tested in the same control and experimental conditions as the goldfish metabolism experiment did. The collected slopes of oxygen concentration will then be converted into oxygen consumption rate and analyzed by the paired t-test. If the difference in the oxygen consumption rate between the control and experimental groups is statistically significant, this experiment will show that caffeine affects the metabolism of frogs, one kind of poikilotherms that use lungs to

    There are approximately seven billion human beings in the world, each having their own culture and traditions. Coincidentally enough, “The Tequila Worm” is based on a small town in Texas, with a family who shares the same family traditions as mine. Viola Canales, the author, talks about the main protagonist, Sophia, and how she celebrates her culture. The making of Easter cascarones, celebrating Dia de Los Muertos, and her connection with her father, Sophia’s life is not so different from mine. Therefore, Sophia’s life and experiences are uncanny similarities to mine and that is what this essay will focus on.

    For instance, we could not conclude that mitochondrial activity is present in Supernatant II. However, our experiment showed that the boiled corn kernels did not undergo any mitochondrial activity while the raw corn kernels did. This might indicate that raising the temperature might have an effect on the function of dehydrogenase. Moreover, our found that starch granules are present in both sediment I and the “gunk”. Indeed, some parts of this experiment were not successful because the procedure was not followed

    Caffeine, Nicotine, ethanol, and a control solution were tested. The heart rate of Daphnia was measured after exposure to each of the chemicals. After testing, it was found that ethanol depressed the heart rate while exposed, but the heart rate stabilized after exposure. With exposure to nicotine, the heart rate increased by 20%. If more nicotine was added, the effects were varied and sometimes irreversible.

    The effects of alcohols on membrane have also been researched quite extensively. Previous studies have found that alcohols disrupt the structure of cell membranes (Goldstein, 1986). They have also found that ethanol has a stronger effect than other alcohols (Patra et al, 2005). From this research and literature the expected results of the experiment were to see an increase in membrane permeability, this result was observed. The study provides a brief insight into what kind of effects alcohol can have on cell membranes but it is limited.

    The Cheese and the Worms by Carlo Ginzburg lets us understand the life and times of a miller, from the rural mountain town of Montereale, made to stand trial for his views on God and religion. In this story, we are able to see how the life of a commoner does not need to be shown in statistics. Through the lens of Menocchio’s trial documents we have the ability to see how one man saw the world and how he interacted with others in his small town. Through his interactions with other citizens of his time we are able to draw conclusions on the world around him. Stories such as Menocchio’s give us an important understanding on relationships in cultures lost to history.
