The Effect Of Ibuprofen On The Heart Rate Of The Daphnia (Crustacean Organism)

938 words - 4 pages

Hard work, good literature Excellent detail and work effortAbstractThe project that I chose to research was the effect of Ibuprofen on the heart rate of the daphnia. The reason that I chose to do this was because many people in society use over the counter pain killers without really understanding any of the long term effects of this medicine other than clearing their aches pains, and swelling. One of the leading drugs on the market today is Ibuprofen which you may know as Motrin or Advil. Both drugs are identical except for quantity and price, and even there it might be the same. The organism I chose to work with is a crustacean called the Daphnia. Later in this report I will attempt to explain the significance of that organism and why I chose to conduct tests on it.I then, with the information at my disposal, conjured a hypothesis which I would test. Using the materials at hand I, to the best of my ability tested my hypothesis. In conducting the tests I created graphs and tables of my work.At the conclusion of my experiment I came up with an answer that was almost unpredictable with the information that I was using. Although this was a crude experiment, I believe that I did gain a lot from it.IntroductionThe drug that I chose, Ibuprofen, is an anti-inflammatory analgesic. It is propionic acid that is white and powdery, and soluble in water, and organic solvents such as ethanol and acetone. (1) Its structural formula is:(CH3)2CHCH2 CH(CH3)COOHIts role of action as a drug is not completely clear to the sciences, but that with time will change. One thing we do know is that people who have allergies to Aspirin should not take this medicine. (2)As of now we know that it may play a role in prostaglandin synthesis inhibition. (1) Prostaglandin are hormonal like substances that form in animal tissue from polly unsaturated fatty-acids. (3) They do affect several body systems including the central nervous, gastrointestinal, urinary, and endocrine systems. It has been shown to have very minor effects on smooth muscle contraction and the clotting ability of blood which we are concerned with.(4) Excesses of these substances may cause pain, inflammation, and fever.It is also an analgesic which is used to reduce or eliminate pain without causing a loss of consciousness. (4) Another name for these substances which we all know of is a painkiller.A water flea or Daphnia, is a member of the subclass Brachiopod, in the order Cladocera. They are found in the plankton of open water. (5) What I was concerned with the Daphnia was the fact that they are transparent organisms. Observing their inner organs is done with ease and what I mainly focused on was the heart.The almost...

Heart rate is defined as the number of beats per minute. Caffeine (C8H10N4O2) is a stimulant drug that is daily used by millions of people around the world to improve mental alertness and

The Effect of Temperature on the Rate of Reaction

1175 words - 5 pages The effect of temperature on rates of reaction Aim: The aim of this experiment is to find out if the reaction rate of sodium thiosulphate solution and hydrochloric acid will be affected by a temperature change. Prediction: I predict that as a result of increasing the temperature of the sodium thiosulphate, the rate of reaction will be faster. Because of the increase in temperature, the particles will gain more kinetic energy. This will

The Effect of Light Intensity on the Rate of Photosynthesis

836 words - 3 pages The Effect of Light Intensity on the Rate of Photosynthesis Plan: Aim: To investigate the affect of light intensity on the rate of photosynthesis. Theory: Before I predict what will happen I must look at how photosynthesis occurs. Photosynthesis is the way plants create a source of food for themselves. Photosynthesis requires the following resources; Carbon Dioxide, Water and light. Inside the leaves of a

The effect of light intensity on the rate of photosynthesis

1641 words - 7 pages to photosynthesise has been proven many times in experiments, and so it is possible to say that without light, the plant would die. The reason that light intensity does affect the rate of photosynthesis is because as light, and therefore energy, falls on the chloroplasts in a leaf, it is trapped by the chlorophyll, which then makes the energy available for chemical reactions in the plant. Thus, as the amount of sunlight, or in this case light


651 words - 3 pages testing the temperature on the rate of enzyme activity is to examine how different temperature might increase or decrease activity. Adding energy in the form of heat to the enzyme will most likely increase activity because more reactions are able to take place. However, cooling down the enzyme and thus removing energy will most likely slow down the process because there is less energy available for the enzymes to utilize for reactions. However

Investigating the Effect of Exercise on Pulse Rate

834 words - 3 pages Investigating the Effect of Exercise on Pulse Rate Aim: To see what happens to the pulse rate during exercise. Prediction: I predict that the pulse rate will increase in order to take more oxygen for respiration. The heartbeat will increase and become stronger to transport oxygen and carbon dioxide to and from the muscle cells. The breathing rate will increase in order to get rid of the extra waste such as Carbon

I then filled each ice cream container with 500 ml of water and put above each container a 100 watt lamp attached to a stand distanced 20 cm from the container.Initially I decided to measure the ph of water after 5 days but the results were not successful as

The Prognostic Importance of Heart Rate Variability

685 words - 3 pages 1.1. Heart rate variability: Heart rate variability (HRV) reflects the variations in the intervals between heart beats (R waves) over time. The time between two consecutive R waves is termed the R-R interval; it is measured in milliseconds, and is controlled by the autonomic nervous system 1. HRV is a non-invasive method for interpreting autonomic nervous system modulation and provides information relating to each branch of the autonomic nervous

The effects of physical activity on heart rate and breathing rate

701 words - 3 pages Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise, we measure the breathing rate

Research Experiment Examining The Effect Of Caffeine On The Heart Rate Of Water Fleas

819 words - 3 pages Introduction: Caffeine is produced by plants as an insecticide. It is a drug that acts as a stimulant in humans and causes a raised heart rate, and is used to give more energy in drinks such as tea and coffee, add flavour to drinks such as coke, and in weight-loss foods. A raised heart rate increases the risk of cardiovascular disease as it makes the heart work faster which can wear it out. High levels of caffeine have been linked to increased

Investigating The Effect Of Alcohol On Heartbeat Of Daphnia

3425 words - 14 pages A-E is that after the Daphnia have been submerged in alcohol their heart rate falls, but after returning to water the heart beat gradually rises. This trend is for the graphs drawn of the average number of heartbeats every 10 seconds, of the 5 Daphnia tested for each of the 5 concentrations. Alcohol has this effect on the heartbeat of Daphnia because alcohol is a depressant and therefore it affects the nervous system of
