C. Elegans Lab Report

Superior Essays
C.elegans is a model organism used within studies involving olfaction. In this experiment, we tested the effects of two chemoattractants, sodium chloride and butanone, on C. elegans behavior to determine which compound was most favorable to the nematodes. A quadrant chemotaxis assay using these compounds (103 mM sodium chloride and butanone) was performed. The control, 250 mM sodium azide, was distributed to each plate. Movement was traced by counting the organisms within each quadrant and the origin to determine the chemotaxis index.Exposure to these attractants minimally affected the movement patterns of the model organism and produced negative chemotaxis values. Sodium azide, the control solution, sodium chloride, and butanone had no influence on the responsive behaviors of C. elegans.

It is composed of two sections: the central nervous system, which includes the brain and the spinal cord, as well as the peripheral nervous system, which is responsible for transmitting signals from the central nervous system to target cells within the body. The nervous system is comprised of neurons, or nerve cells, that rule how an individual will respond to a stimulus. Sensory neurons, such as the ASE neuron, receive a stimulus from the internal or external environment through dendrites, and convert the stimulus into a signal that is sent into the central nervous system (Urry et al. 2013). Interneurons located within the central nervous system serve as a bridge between sensory and motor neurons, which determine one’s physical responses to stimuli (Urry et al. 2013). Through a lattice of neurons, organisms are able to perform various tasks that are meant to deter them away from stimuli or encourage the interpretation 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 Morris water maze was large 180 by 60 v centimeter high tank. The tank was filled to a 22 centimeter with water and nontoxic white paint. The maze included a circular platform and it was opaque because it was 3 to 4 centimeter below the surface. The features of the research room was same throughout the experiment and represented visual cues as guidance. The rat was placed in the maze and swam until the platform was found.…

    Bed bugs have similar engorgement characterizes as many other bugs when it comes to the sodium solution concentrations. When offered only water versus when a solution that contained phosphate-buffered saline (PBS), the later was what was found to be the situation where more engorgement occurred. It was expressed that mouthparts that bring about the acceptance of different concentrations of sodium chloride are receptors known as gustatory receptions. In the instances lower sodium was engorged and high sodium was rejected.…

    We hypothesized that pill bugs would display a positive hydrotaxis and a negative chemotaxis, but our last experiment supports a reaction to chemotaxis. Since we placed them in a tray with all chemical-filled chambers, we weren’t able to tell if they drift towards diluted solutions because they contained more water. The products of the Chi Square Test told us whether the results of our experiments were significant or not. Our results in Part A and B were significant because the calculations proved the null hypothesis wrong and supported our hypothesis; the bugs displayed a positive hydrotaxis and a negative chemotaxis in these two situations. On the other hand, Part C can be invalidated because the bugs did respond when placed between 4 concentrated-chemical solutions.…

We focused on the role of three sensory neurons in the nose of the nematode—the 1) AWA and 2)…

    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.…

    Purpose The purpose of this lab is to investigate animal behaviors by diving into the world of ethology. There are two ways pill bugs will respond to environmental stimuli: Kinesis (non-directional response) and taxis (directional response). Kinesis occurs when organisms (randomly) move around quickly when they’re unhappy and slowly when they’re happy, which is best demonstrated when one lifts up a rock or other material that the pill bugs are under. In contrast to the simpler response that does not necessarily involve many neurons, taxis is often observed in response to changes in light, heat, moisture, sound, and/or chemicals (odor).…

The integrity of the control (water) was maintained by using an eye dropper to carefully place the water into the selected chamber to test the effects. There were no major complications during the experiment. The biggest complication was the lack of movement from the pillbugs which may have made the…

    Instead a crayfish in cold water and a crayfish in room temperature were both calm the moment they were taken out of water, while the other two crayfish took their time with getting comfortable. Although the crayfish exhibits habituation, dishabituation,stimulus generalization and spontaneous recovery as its defense reflex, when stimulated with rapidly approaching targets (Glantz, R.,1974), it did not truly show if temperature had any significance to its behavior. These results tell me that temperature could have possibly not have any effect, however it does bring several other factors to the light. Some things that we missed while selecting the crayfish was gender, age and size. With the factor of size, being missed during this experiment, other researchers have found that size is directly related to behavior in both genders.…

    The Family Tetraodontidae and its Toxic Defense Mechanism Tetraodontidae, a family commonly known as the pufferfish, uses unique defense mechanisms in the wild to protect themselves against predators. Pufferfish diet consists mainly of invertebrates, so they are not viewed as dangerous or predatory animals in their ecosystems. These defense mechanisms are necessary to the survival of the Tetraodontidae family. The Tetraodontidae family’s defense mechanisms of inflation and use of the deadly neurotoxin tetrodotoxin make the family especially devastating to any predator that dares to ingest it.…

    The acids in the detergents had broken the fat in the cell membranes to the extent where the proteins were no longer able to hold their shape. The acidity of detergents plays a role in the ecosystem. If the pH is too high (alkaline) the cell will expand all the large solute molecules are able to pass through the semi-permeable membrane and if the pH is too acidic then it also does the same thing and allowed the larger solute to diffuse, it also makes the cells shrivelled not being able to hold shape. Out of all the detergents that were tested it shows that earth is the better detergent to use for it takes a higher concentration for the lip bilayer to break down to the extent that dynamo did for both experiments 1 and 2, Earth’s solution only changed colour when the beetroot was left in a 20% solution overnight not when the beetroot was kept 10% solution. The beetroot also didn’t lose its shape or much mass in experiment…
