Internal temperatures can modify the contraction of the heart by increasing or decreasing heart rate.5 The goal of the experiment was to subject the crayfish to different conditions to monitor the change in contractility of the
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.
Introduction: Isopods are crustacean, which is split into smaller groups, called order. Scientifically Isopoda order is called isopods, which include pill bugs and sow bugs (Crustacean class). Most of the time isopods are mistaken for “bugs” since they look like insects.
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.
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.
2013). A sinusoidally oscillating sphere was used between frequencies 5 to 150 Hz using a two-alternative forced study (Gaspard et al. 2013). 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). Vibrissae were restricted with mesh of different sizes ranging from large (10%, 3.175 mm) to extra fine (100%, 0.035 mm) (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
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.
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.
Kilgore Trout and Dwayne Hoover had an interaction with each other and with other characters also where dehumanization takes place. It is the personal qualities which give Breakfast of Champions discouraging and cold hearted mood. Dwayne Hoover and Kilgore Trout was representative of success and failure in dehumanization in the society. In this book Vonnegut invented like electric chair, bull, alien, etc.
An overall engaging story; doesn’t rely on too many actions. The story goes because of Joanna’s internal conflict. Her thoughts drive the story along with the descriptive language. This language pulled me in. So much attention went into the details to show how numb her mind and body is at this point, especially when she has arrived at her house and the story reflects on how “the New Jersey highway system [left] her body a limp bundle of cord and nerves” (1).
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
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.
In this essay I will argue that the reasoning behind perdurantism, more specifically worm theory, is more satisfactory in explaining the persistence of the milk over time then the opposing endurantist claims, though it is not without fault. It is first important to examine what we mean by identical. It is important to distinguish between being qualitatively and quantitatively identical. If the object was qualitatively identical, then it must possess all the same qualities, and if an object is quantitative the same, then it will also possess the same spaciotemporal property. With regards to whether the fresh milk and the sour milk are identical, we are referring to their quantitative identity, so whether they are in fact the same ‘thing’.
Kandel studied sea snails and other animals with simple nervous systems in an attempt to explain what memories are: synapses or cells? Kandel stimulated the snails’ sensory neurons directly with electrodes. By a process of elimination, neuron by neuron, he mapped out the entire neural circuit of a simple behavior in the snails (the gill-withdrawal reflex) that changes and learns in response to its environment. Then, by removing parts of the circuit to a petri dish and subjecting the neurons to electric shocks and different chemicals, this changed the three neuron circuit in the snail. Function of the neuron changed with increase in the amount of the neurotransmitter produced by the neuron.
