Operculum Movements
Results
My fish was administered Ketamine and a change of operculum movements was seen when you compare the baseline average of Table 1 to the operculum movements when the drug was introduced in Table 2. This difference marked a behavioral abnormality of the fish and consequently the drug dispensation was stopped. Another abnormality in behavior was the fish having rhythmic breathing and swimming compared to erratic breathing and stationary movement. It appears that the operculum movements increased when the drug took effect. It went from 41 mvmt. /minute to 71 mvmt. / minute as seen in Table 2. This would suggest an increase in metabolic rate. However, the behavior of the fish showed that it had rapid operculum movement to periods of no operculum movement which would represent a decrease in metabolic rate. My fish was the only fish to have an increase in operculum movement when 1st effect was observed.

Each fish experienced a deviation from its normal behavior. Many fish became stationary, some spastic, while others appeared to be dizzy. It shows in this table that Ketamine had a faster effect on the fish and was given in smaller concentrations than Isoflurane. This is also shown in figure 1. The R- value was 0.7772. In figure 2, the percent difference varied among all fish. The fish who inhaled Isoflurane had a slightly higher percent difference than those given Ketamine. This means that there was a higher metabolic rate change. The R-value was calculated to be 0.3857. In table 4, the t- test determined that there was a statistical difference between the concentration means when the first effect of the drug was seen. If the p-value was less than or equal to 0.05 then the mean concentrations are significantly different from each other which is the case for this

    For the Daphnia heart rate experiment, the Daphnia was subjected to different chemicals via submersion. These chemicals were used as stimuli to prompt altered cardiac activity. The altered cardiac activity, measured through heart rate, would clue to whether a chemical is having a stimulant or depressant effect, or if any effect at all. Marley et. al discusses the effects of stimulants and depressants on the CNS (central nervous system). Research by Marley suggests that depressants tend to slow down activity of the CNS, while stimulants enhance over-activity of the CNS. Past literature shows that cardiac activity is autonomous and controlled by the CNS. In the Daphnia heart rate experiment, these two principles are tested together, and used to determine if unknowns A and B are stimulant or depressant. For the Human ECG circulation experiment, two human subjects were observed under resting, mild exercise and high exercise conditions. The mild exercise condition was produced by having the subject do repetitive…

    In the following experiment, the key objective is to compare the mechanical changes in tonic force by longitudinal smooth muscle after the addition of different concentrations of the drugs noradrenaline and acetylcholine. Peristalsis is the wave of muscle contractions that allow circular muscles to constrict the gut and longitudinal muscles to shorten it in an attempt to move the food bolus towards the rectum. A series of dilutions were prepared for both drugs to deduce the effect this would have on the contractions of the mammalian gut. These were added, in turn, to Ringers solution containing the gut (a solution resembling blood serum in its salt constituents used for bathing and culturing animal cells1). Both drugs caused various changes in parameters: tension in the gut and rhythmic contractions. A kymograph helped us measure these parameters in order to draw conclusions to differentiate between the effects of the two drugs at different concentrations on the motility of the gut. Smooth muscle activity is controlled by the autonomic nervous system where the sympathetic and parasympathetic divisions work against each other, thus this experiment allowed us to deduce how one division slows the digestive system and the other accelerates it.…

    The t-test is a parametric analysis technique used to determine significant differences between the scores obtained from two groups. The t-test uses the standard deviation to estimate the standard error of the sampling distribution and examines the differences between the means of the two groups. Since the t-test is considered fairly easy to calculate, researchers often use it in determining differences between two groups. When interpreting the results of t-tests, the larger the calculated t ratio, in absolute value, the greater the difference between the two groups. The significance of a t ratio can be determined by comparison with the critical values in a statistical table for the t distribution using the degrees of freedom (df) for the study. The formula for df for an independent t-test is:…

    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…

    In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate, an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1, we observed the basal rate of three different worms, and then placed the same three worms on different concentrations of caffeine and nicotine. “Caffeine is known to act as an inhibitory neurotransmitter in the brain; it promotes sleep and suppresses aurosal, binding to the adenosine neurotransmitter receptor to block its inhibitory action” (CCNY lab manual, 2014). Before our experiment was conducted we hypothesized that increasing the concentration of caffeine will increase the pulsation rate. During this experiment we used 1.0mM, 3.0mM, and 10.0mM concentrations of caffeine. The highest the concentration the more effect it would have on the pulsation rate, so in this case we could assume that 10.0mM would have the highest effect on the pulsation rate of the blackworms.…

    The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control, elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of water. The increase in volume of the water would represent the volume of the two test subjects. We then covered each beaker with plastic, but for the elodea we placed it under a can so it could be in the dark. After waiting 15 minutes to allow them to respire we took it out and add four drops of phenolphthalein, which was also acidic, to both beakers. Once both beakers got their four drops we added drops of NaOH, which was a base, until the solution turned pink. Our results were that the respiration rate of the crayfish was higher than the elodea.…

    A researcher wanted to determine if a new anti-anxiety drug decreased anxiety levels. Three hundred patients were given the new drug and three hundred patients were given a placebo (also known as a “sugar pill” that does not contain any medicine). All of the patients were told they were receiving the new drug and were monitored for six months. At the end of the six months, all of the patient information was analyzed and the researcher concluded that because the patients given the placebo indicated the same reduction in anxiety as the patients given the new drug, the new drug was ineffective in decreasing anxiety levels.…

    My results and the graph indicate that as you add the caffeine to the daphnia, the eart rate of the daphnia increases for example the daphnia's heartbeat is 120 without caffeine, however when caffeine is added it is increased to 168. My graph shows a positive correlation and the error bars are also very small which shows that the results have a small range which suggests that my results are accurate and reliable. I think that the experiment was conducted well however there may be some ethical issues surrounding the fact that daphnias are also living species. Therefore, by using daphnias in these experiments may cause a risk for them as there would be little quantities of the species left. This would also affect other living organisms that feed on daphnias for their dietary needs therefore in the experiment we diluted the caffeine solution with distilled water to prevent the daphnia from dying and afterwards, we could put them back in their natural habitats. On the other hand, by doing this experiments it could potentially help us in the future. Also, another problem is that I may have miscounted the daphnias heartbeat due to human errors. However, as I repeated the experiment 3 times, it ensures me that the data is quite accurate. However, if I was to do the experiment again I would do more repeats to make sure the results are reliable and there would be less chance of human error. Also, I would use different concentrations of caffeine to get more accurate comparisons and to see how different concentrations may affect the daphnias heartbeat also. Overall, I think that my results are precise and distinct.…

    We filled three containers with three different concentrations of caffeine. The first container was our control with no caffeine, the second was filled with a .5% concentration of caffeine, and the third was filled with a 1% concentration of caffeine. Five daphnia were then placed in each container for ten minutes. After the daphnia were exposed to the concentrations for ten minutes, we used micropipettes to remove them from the solution and place them under a compound microscope. While they were under the microscope, we counted their heartbeats for twenty seconds then multiplied the number by three. Each group of daphnia's heart rates was averaged to get a more accurate heart rate for each concentration.…

    The purpose of this laboratory exercise was to demonstrate and explain the effects caffeine on the circulatory system of blackworms and to test the hypothesis that high concentrated caffeine will double the heart rate pulsation of blackworms. Blackworms have several complex systems including a closed circulatory system: a complete digestive tract: and a nervous system, including a brain and a cord. Because of the transparent skin of the blackworm, its large dorsal blood vessel is very easy to see through the microscope. Since the rate of pulsation is easily seen and calculated it’s easy to test the effects of different chemicals on their cardiovascular system. Since it’s known that caffeine increases the blood pressure one might expect that the blackworms under the influence of caffeine will show a grater average of pulsation rate.…
