Daphnia Hypothesis
In this lab, the problem was, how do certain types of drugs affect body’s homeostasis. The drugs tested were prescription painkillers and hemp. The hypotheses stated that both drug were depressant drugs thus meaning that heart rate, and along with it, metabolism. The hypotheses are, in fact, true statements that can be backed with the data collected. The initial heart rate before the drug, hemp was applied, was 216 BPM. The final heart rate, with the drug was 132 BPM. That is a change by -84 BPM. This proves that hemp lowered the heart rate of the Daphnia, like the hypothesis stated. The overall average for all the groups, there is a similar trend with a -7% change meaning the every test had the same outcome of the heart rate decreasing. There …show more content…
The Daphnia could have some leftover effects from the previous testing. The two daphnia tested were not the same size or had the same BMI. So thes could mean that certain types of drugs work faster when a person is skinnier or fatter, thus meaning the drugs didn’t take their full effect at the same time. This meaning that when the data was being recorded when the drug wasn’t at its highest peak of effectiveness. Assuming that the Daphnia and huma react in similar ways with drugs, the bugs might act completely different from another. Sometimes people need more of the drug to get it’s effects or vise versa. Meaning the data is not universal and definite. The altitude could might as well affect the rate in which a drug kicks in. Similar to all the other SEES, this means the data might not be when the drug is in full effect. Some might have been looking at the lungs instead of the heart meaning the data would be about the lungs instead on the determined heart rate. If the slide was not fully cleaned off and had residue from the previous drug the Daphnia could have absorbed that left over drug and had some of effects from the sed drug. Meaning that the heart rate could have gone up a litle or down a little showing inaccuracy in ONE certain drug and its effects on heart

    We took an indented microscope slide and out the daphnia on it with water and put another intended slide over it. After that, we put the slide into room temperature water (18 degrees Celsius) to measure the daphnia’s normal heartbeat per minute. After that, we put the slide under the microscope and counted the number of beats per 15 seconds. We then repeated the procedure with water that was 4 degrees, 8 degrees, 26 degrees and 33 degrees Celsius.…

    The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight, hearing these could be attributed to loud noises or too much light going into your eye. Chemical stimuli differ because chemicals such as caffeine and alcohol usually cause these to affect cognitive abilities and heart rate. These same things can also affect muscle response and glandular response causing twitches and the production…

    Essay On Daphnia Magna

    The purpose of this study is to understand the feeding rate of Daphnia magna. D. magna is a species of Daphnia that belongs to the suborder Cladocera (Ebert, 2005). They live in freshwater and feed on small, suspended particles in the water. They are filter feeders. Phyllopods, which are leaf-like appendages, provide a filtering apparatus for the collection of food. These structures beat to produce a constant current of water, allowing particles to be filtered by fine setae on the thoracic legs. The particles are then transferred to their mouth groove to be ingested. D. magna typically feed on planktonic algae (Ebert, 2005). The following experiment uses algae to test what affects the feeding rate of D. magna. The rate of filtration is dependent on multiple factors including temperature, food density, body size, and water pH.…

    Daphnia Experiment

    In this laboratory experiment, our control was the Daphnia that gets spring water, whereas the drugs were the independent variable and the heart rate was the dependable variable. The first step our group did was to place the Daphnia into a clean depression slide. Next, we added a small drop of the spring water and put a cover slip over the slide. Then, we waited for one minute prior to placing the slide on the microscope in order to allow time for either solution or the drug to take its effect. After we put the slide on the microscope, we located the heart of Daphnia and counted its heartbeats while the other member kept time for each three 10-second trials. We recorded our data and calculated the average heart rates of three trials we found during the experiment. Afterwards, we calculated the average 60-second heart rates by multiplying the averages of our 10-second heart rates by 6. These procedures were repeated with the rest of solutions as well, including caffeine, aspirin, alcohol, sleep-aid, and…

    : If daphnia are exposed to poor water quality from manmade factors such as car antifreeze, plant pesticide and cigarette ash then their quality of life decreases and changes their behaviors and potentially kills them because the harsh chemicals cause their natural functions to shut down and cause death. Although my hypothesis was partially correct I believe there are more factors than just the introduction of chemicals that would weaken the daphnia. Before my experiment I had designed my plan to observe the daphnia for an hour but I had to change my time to a half an hour due to lack of time I had left after setting up my experiment. I would observe two petri dishes at a time rather than all 4 at the same time. If I could redo my research…
