Recommended: The process of homeostasis

This experiment intends to investigate the homeostasis of Lumbriculus variegatus as it is affected by three different drugs. Homeostasis is the the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. A living organisms bodies goal is to keep homeostasis so that the body can run properly. The purpose of medical science and pharmaceuticals in general is to make compounds and medications that aid in the human bodies attempt to stay at homeostasis. These worms will have these three substances: alcohol, caffeine, and nicotine applied to them in either "high" or "low" concentration. Alcohol is a depressant meaning that when it enters the body it slows down and relaxes the organism. …show more content…

Nicotine works as both a depressant and a stimulant depending on the dosage. The experiment will be separated into 6 groups each testing a single substance at either high or low concentration. These groups will be recording several worms heart beats in order to prove each individual's personal hypothesizes on which solution will have the greatest effect and which substance with having the weakest effect. Due to the toxic nature of nicotine, it is hypothesized that nicotine at high concentration will have the greatest effect on the worms. It is hypothesized that the low concentration of caffeine will have the weakest effect. The goal of this experiment is to find which substance at which concentrate has the strongest and weakest effect to better understand homeostasis. This experiment also will provide insight into how these three substances affect living

  • Artemia Franciscana and Preference Regarding the Effects of Light, Temperature, and pH.

    The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in saline lakes, can survive pH ranges between 7 and 10 with 8 being ideal for cysts(eggs) to hatch (Al Dhaheri and Drew, 2003). Based on this fact alone the tested A. franciscana should show preference to higher pH levels. In nature A. franciscana feed by scraping food, such as algae, of rocks and can be classified as a bottom feeder; with this said, A. franciscana are usually located in shallow waters. In respect to the preference of light intensity, A. franciscana can be hypothesized to respond to light erratically (Fox, 2001; Al Dhaheri and Drew, 2003). Using these predictions, and the results of the experimentation on the A. franciscana and stimuli, we will be able to determine their preference towards light, temperature, and pH.

  • Caffeine In Blackworms

    With over nine hundred and seventy one tons, the United States is the country with the highest amount of caffeine consumption in the world. This chemical compound is known to have many affects on our bodies, primarily in our hearts. Caffeine has been shown to increase blood pressure and heart rate. However, as far as scientists know, the affects of caffeine may affect invertebrates differently than it affects vertebrates. The present experiment studied blackworms - Lumbriculus variegatus in the phylum Annelida- in solutions with different amounts of caffeine to see if it affected their pulse under a compound microscope. Worms do not have hearts; they have aortic arches that contract to push the blood into the dorsal and ventral

To prepare the variable treatment, 200ml of Sodium and Ammo-lock water was measured in a container and a pre-prepared “tea bag” of tobacco was steeped in the room temperature treated water until a light yellow color was visible. After preparing the tobacco solution the preparation for the live goldfish began as two beakers were filled with 100 ml of treated water. Each beaker was weighed before addi...

    The procedures for this experiment are those that are referred to in Duncan and Townsend, 1996 p9-7. In our experiment however, each student group chose a temperature of either 5 C, 10 C, 15 C, or 20 C. Each group selected a crayfish, and placed it in an erlenmeyer flask filled with distilled water. The flask’s O2 levels had already been measured. the flask was then placed in a water bath of the selected temperature for thirty minutes, and then the O2 levels were measured again. Each group shared their findings with the class. The metabolic rates of the mouse were conducted by the instructor and distributed. We also did not use the Winkler method to measure the O2 levels. We used a measuring device instead.

  • Lab Report The Effects of Drugs on Cardiac Physiology

    1801 Words  | 4 Pages

    The second part of this lab was a computer simulation program to illustrate a frog’s electrocardiogram using various drugs in an isolated setting. The computer program entitled “Effects of Drugs on the Frog Heart” allowed experimental conditions to be set for specific drugs. The different drugs used were calcium, digitalis, pilocarpine, atropine, potassium, epinephrine, caffeine, and nicotine. Each of these drugs caused a different electrocardiogram and beats per minute reading. The calcium-magnesium ration affects “the permeability of the cell membrane”(Fox). When calcium is placed directly on the heart it results in three physiological functions. The force of the heart increases while the cardiac rate decreases. It also causes the appearance of “ectopic pacemakers in the ventricles, producing abnormal rhythms” (Fox). Digitalis’ affect on the heart is very similar to that of calcium. It inhibits the sodium-potassium pump activated by ATP that promotes the uptake of extracellular calcium by the heart. This in return strengthens myocardial contraction (Springhouse). Pilocarpine on the other hand

  • Tobacco and the Brain

    Smoking cigarettes produces a rapid distribution of nicotine throughout the body, and reaching the brain within 10 seconds of inhalation (4). The nicotine causes a release of dopamine, neurotransmitters that carries information across synaptic clefts, in the dopamine circuit. This circuit, known as the brain's pleasure center, is an anatomically small cluster of cells. It has evolved over millions of years and mainly seems to reward activities that increase the likelihood of survival, such as sex and eating. This cluster of cells might be small but it reaches into regions of the brain involved with a variety of tasks (4). . These dopamine-releasing pathways course from the evolutionary older part of the midbrain to the hypothalamus and trigger activity of other cells, that extend from one part of the midbrain to an area in the forebrain known as the nucleus accumbens (2). It also branches out t...

    An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.

    Smoking cigarettes is a very deadly addiction that, unfortunately, affects 42.1 million adults in the United States and 6.4 million children. The reason why so many people get addicted to cigarettes is because of nicotine. Medicinenet.com says that nicotine is “made by the tobacco plant or produced synthetically”. Nicotine has powerful pharmacologic effects (including increased heart rate, heart stroke volume, and oxygen consumption by the heart muscle), as well as powerful psychodynamic effects (such as euphoria, increased alertness, and a sense of relaxation). Nicotine is also powerfully addictive.”
