Temperature Of Daphnia Magna Experiment

Decent Essays
Our research question being addressed in this experiment is whether or not escalating the temperature of Daphnia magna's environment will greatly impact the expression of its haemoglobin gene. In addition, we also want to observe if there are negative consequences that can possibly occur from this escalating gene expression. This can also be linked to whether or not global warming has been affecting Daphnia, a primary and crucial source of food for many organisms in freshwater habitat, negatively. Our hypothesis for our experiment is that if there is an increase in temperature in the habitat of Daphnia magna, then there will be increased gene expression of the haemoglobin gene. Our main expected outcome, according to background information,

    Prepare a chart for recording any observations as you test for the presence of cations in the solution. Set up and label 10 test tubes #1- #10 and place them in order in a test-tube rack. Wash and rinse all of glassware with distilled water. Prepare a hot-water bath in a 250 mL beaker by filling it up to 150 ml and bringing it to a boil. Obtain 2 ml of the solution you want to test and pour it into test tube 1.…

    The densities of 3 different solutions, water, saltwater, and an unknown solution, were calculated using a triple beam balance and a graduated cylinder. Density was also used to discover how much zinc and copper are found in a penny. The following results were found: water’s density, 1.02 g mL-1; saltwater’s density, 1.05 g mL-1; and the unknown substance labeled two’s density, 1.04 g mL-1. The percent error was calculated for water’s density as 2%. The composition of a penny was calculated using volume by water displacement and the mass of the pennies.…

    The effects of caffeine on Daphnia magna Lee Phan Lab Section: P0501 1000587723 1. Materials and Methods: Preparation: Clean 3-well specimen chambers were kept in ice and a cooling chamber was then prepared to be put under the microscope, by filling it with ice and a small volume of water. This was done to ensure the temperature would remain around 15 degrees Celcius, which could keep Daphnia magna efficiently cool.…

    RESULTS: An experiment was conducted to document the patterns of evolution in the fictional species, Cannus stannous. Fitness of the C. stannous population is determined solely by its ability to retain heat. Three genes determined heat retention; can size, skin type, and water level. Each gene had three alleles, producing 27 possible phenotypic combinations (Table 1).…

    The organism Daphnias affected affected by affected the the different chemicals in the the environment. Daphnia cannot not live in every environment therefore, when it’s not in it’s not in its natural environment [4]. I observed how Daphnia in either ethanol, caffeine, acid and base impacted the heart rate of the Daphnia. Daphnia have proven to respond to some cardioactive drugs that are known to affect human heart function [6]. I conducted two different experiments which helped me understand more about how daphnia can be affected by the environment that they live in.…

    Compensation is the maintenance of the levels of physiological processes, despite changes in temperature. This experiment was coordinated to determine whether crayfish will show metabolic compensation when acclimated to various temperatures. The findings of this study show that temperature had no effect on crayfish oxygen consumption. The oxygen consumption for both the warm and cold acclimated crayfish was almost the same, despite the opposite direction of the temperature change. The results of this study therefore support the hypothesis.…

    As the temperature increases, the rate of reaction increases until it has reached the optimum temperature above 37°C where the temperature is very high then the reaction rate will decrease. In the data table shown above, there is a similar pattern from increasing the temperature will increase the rate of reaction and as the temperature slowly increases to a certain point then the reaction rate will decrease. When the temperature increase above 37°C, then denature will occur. Also, the temperature increase, the kinetic energy where H2O2 molecules bind frequently with the catalyst increase the enzymes. Conclusions: An enzyme speeds up the chemical reaction, the activation energy allows energy to require to break bonds apart and lower activation…

    The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well.…

    When algal blooms are prevalent in bodies of water, specifically bays, they can cause the nitrogen levels in the water to increase. When the nitrogen levels in the water are increased, this can lead to a number of detrimental health effects when consumed. In order to determine whether or not the salinity of the water in Barnegat Bay had an effect on the rate of the nitrogen levels increasing during an algal bloom, ten sample of water were collected and tested by adding the microalgae Nannochloropsis and recording the nitrate and nitrite levels every week. The sample of water varied in salinity, and two samples did not contain the algae to act as a control. The samples were exposed to a temperature of 22°C and were tested over the course of…

    The objective of the lab was to find the calorie content of Cheetos and marshmallows. To do this we needed to use a calorimeter. The hypothesis was that Cheetos would have more calories because they have more fat in them. The Cheetos and marshmallows were lit and put in an oatmeal can calorimeter. The temputure change in the water leads to finding the calories in food.…

    One of most imperative factors regulating survival and growth invertebrate larvae, including O. vulgaris is temperature (Kamler, 1992; Boidron-Metairon, 1995). If the temperature is not in suitable, the growth of paralarvae are disrupted and can result in poor development or even high mortality. Consequently, it is a significant bottleneck in the culture of Octopus vulgaris aquaculture. Studying the effects of temperature stress on paralarvae and acquiring knowledge on how it the influences survival during the larval…

    Osmoregulation in Cyclograpsus and Plagusia crab species Hartzer, A.M, 19971613, First year BSc student, Stellenbosch University, South Africa Abstract Osmoregulatory processes within two crab species are investigated in this practical. The Plagusia, an infratidal species, and Cyclograosus, an intertidal species, are investigated to determine which is an osmoregulator and which is an osmoconformer. The haemolymph was extracted after allowing the species to acclimatize to varying concentrations of seawater. The comparative melting-point technique was used in the experiment where capillary tubes were used to collect samples of the seawater and blood, then frozen and put into an alcohol bath.…
