The Effects Of Alcohol On The Heart Rate Of Daphnia Magna

ABSTRACT This report presents the physiological changes in the heart rate of a fresh water crustacean Daphnia magna when exposed to caffeine and alcohol. Different Daphnia magnas were placed in a depression slide containing fresh water and later exposed to solutions of caffeine and alcohol. Each Daphnia magna had different responses. These data suggest there is an increase in heart rate when a Daphnia magna is exposed to caffeine and a decrease in heart rate when it is in a solution of alcohol. LAB REPORT Title: Physiological Changes in the Heart Rate of Daphnia magna When Exposed to Stimulants (Caffeine and Alcohol). Prepared for: Professor Samantha Snavely By: Carolyn Omar Iduh June 27, 2015 Introduction The inverse effects between the consumption of stimulant like caffeine and depressant like alcohol has been well established over the years. Alcohol has a paradoxical effect that makes it first appear as a stimulant (American heart association, 2015). The two faced nature is due to ethanol the most active ingredient in alcohol. Alcohol slows down the nervous system by acting on the brain’s inhibitory neurotransmitter called gamma-aminobutyric acid. Studies have shown Bradycardia (slow or decreased heart rate) in people who consume too much alcohol (ehealthMe, 2015). Drinking alcohol can completely alter a person’s concentration, mood, and coordination (National Institute on Alcohol Abuse and Alcoholism, 2013). Too much consumption of alcohol couldShow MoreRelatedEffects Of The Heart Rate From Caffeine And Ethanol1137 Words   |  5 Pagesdifferences of the heart rate from caffeine and ethanol. By understanding the topic, it can be proven that these drugs affect organisms in a certain way, such as the heart rate. The information, collected following the experiment, can be inferred in recognizing the way our body responds to chemicals when drinking coffees and colas. The experiment was conducted by inducing the species Daphnia magna to both caffeine and ethanol, while being compared to a controlled group. Daphnia magna are small crustaceansRead MoreLab Report Daphnia1855 Words   |  8 PagesEffects of Alcohol, Caffeine, and Temperature on the Heart Rate of Daphnia magna Joseph Ezra Gallo BY124L MW 8:30-11:30 Introduction Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal isRead MoreScientific Paper on a Water Flea751 Words   |  4 PagesThe Effects of Alcohol and Caffeine on the Heartbeat Rate in Daphnia Magnus ï ¿ ¼ Erika Huizenga Ashley Kofahl The Effects of Alcohol and Caffeine on the Heartbeat Rate in Daphnia Magnus Abstract The projects purpose was to determine the effects of alcohol and caffeine on the heartbeat rate in Daphnia Magnus. Our hypothesis is alcohol causes a decrease in heart rate, whereas caffeine causes an accelerated heart rate, predicting that the more caffeine we give the daphnia the faster itRead MoreAdipic Acid43555 Words   |  175 Pagesimport amount in 2004 reached 173 700 tonnes, an increase of 30.2% over 2003. The import amount of adipic acid has increased at an annual rate of over 30% for four consecutive years and the dependence on import has reached more than 50% (Xudong Zhang, 2005). Due to the high demand on import, the market price of adipic acid has started at a very high rate. In the years after 2001 the price of imported adipic acid was maintained at RMB 9 000-11 000 per ton in the domestic market. The price of
