The consequence of Alcohol and Caffeine within the Heartbeat Rate in Daphnia Magnus

Summary

The tasks purpose was to determine the consequences of alcohol and caffeine on the heartbeat price in Daphnia Magnus. Each of our hypothesis is usually alcohol causes a decrease in heart rate, whereas caffeine causes an accelerated heart rate, forecasting that the more caffeine we offer the daphnia the more quickly it heart beat rate will become and the heartbeat rate will certainly decrease as we give the Daphnia alcohol. Following doing the experiment all of us found that the more caffeine we added to the Daphnia Magna the faster their heartbeat level became. We also found that after we added alcohol to the Daphnia the heartbeat rate also increased not promoting our speculation.

Methods and Materials

Position: Washtenaw Community College, 4800 East Intratable Drive, Ann Arbor, MI 48105 LA building 205 at 12: 30p. m. January 31, 2010 Supplies: microscope, two glass micro slides, two pipettes, three Daphnia Magna, 2%, 4%, and 6% alcohol, 1%, 1 ½%, and 2% caffeine, aquarium water, a stopwatch, a person to record the data, administer the drugs and water to the Daphnia, and a person to count the heat beats. Procedure for the control: Help to make sure that alcoholic beverages and caffeine are the parameters effecting the heartbeat price we began by capturing a live Daphnia and placed that in a despression symptoms slide which has a drop of pond drinking water from the traditions jar. All of us removed any extra water with the hint of a newspaper towel. Up coming we added one drop of aquarium tank water to the Daphnia. Then simply we started to count the quantity of heartbeats pertaining to 10 mere seconds and then increased by 6th to find the beats per minute and recorded the end result. After two minutes we all repeated the task, and the again after one other two minutes to get three examining of pulse rate on the control. Process of alcohol and caffeine: To determine the effects of liquor...
