Daphnia heart rate ethanol
WebWhen looking at the effects nicotine and ethanol had on the heart rate of the Daphnia magna, it showed that they were depressants by the decrease in the Daphnia’s heart rate in comparison to the heart rate of the control group. The results of Ceballos et.al (2010) supported the results obtained in this experimental. WebWhen the daphnia were in 5% ethanol, the rate of their heart change percent decreased, on average, by 21.70%, compared to when they were in water, as seen in Figure 1. When …

WebExplains that the daphnia's heart rate rises gradually after being submerged in alcohol for 180 seconds. when returned to water from their environment, it increases further. Analyzes the graph of the mean percentage decrease of heart rate when in alcohol against the log10concentration of alcohol. WebOur 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 …
WebMethods: In this lab, we tested the effect of caffeine and ethanol for the Daphnia’s rate of action potentials sent by measuring their heart rate within fifteen second intervals. We hypothesized that when caffeine is added to the Daphnia the heart rate will be greater than when ethanol is added because action potentials will be greater.
