Goldfish Respiration Rate

The temperature decrease results in alterations of the autonomic sympathetic response[11] and in impaired conduction velocity of the electrical signals through the

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 is cold, its heart rate will lower. When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell, 2005)

The respiration rate for the control goldfish ranged from 123 to 140 breaths per minute, which was not a significant change. On average, the cold-water treatments caused a significant decrease in breaths per minute by the end of the experiment. The average the breathing rates of goldfish subjected to temperatures less than 22°C decreased from a rate of 96 breaths per minute at the start of the experiment, to 56 breaths per minute at the end (Figure 1). The experimental fish in Group #1 ranged from 115 to 50 breaths per minute. Overall, the control fish’s breath rates generally remained constant, and the temperature-stressed goldfish had rates that decreased rapidly from start to finish.

Freeman (2008) furthers Eckert et al’s argument by stating that the actin filaments of the muscle cell in organisms are able to intake ATP (adenosine triphosphate) faster and will move the organism faster when higher temperatures are imposed. This is because of an increase in enzyme reaction rates (Freeman 2008). These arguments can be applied to our experiment to help explain the trends observed. It can be argued that as the Gammarus setosus experiences the cold treatments, the organ of Bellonci senses the cold temperature, which in turn signals the organism to preserve its energy to protect itself; therefore, the organism will swim slower. In addition, the enzymes in the muscle cells of the organism, when experiencing the cold treatments, will have decreased ability to carry out enzymatic reactions, therefore inhibiting the uptake of ATP, which will cause the organism to swim slowly. Conversely, as the organisms are put into the heated treatments, the organ of Bellonci senses the heat, and allows the organism to swim faster, since it does not have allocate as much of its energy towards survival. Furthermore, the enzymes in the cells will be able to catalyze reactions more quickly, therefore allowing the organism to swim faster. However, when the temperature of the surroundings is too high, the enzymes will denature, therefore, reducing the activity rate of

direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate

The purpose to this experiment was to study the effect of osmosis in de-shelled chicken eggs in different percentages of sucrose solutions. Osmosis is the process, in which, water moves across a differentially permeable membrane. The eggs were soaked in vinegar to remove the outside hard shell but still leave the egg in its membrane. By placing the six de-shelled in different sucrose solutions, we tested the rate of osmosis. The eggs were placed in the solutions for an hour and weighed in fifteen minute intervals. Then, each weight was recorded and graphed. The results showed that the egg in the water solution gained the most weigh and the only other egg that gained a little weight was the one in the 10% solution. All the other eggs in the different solutions lost weight, even the unknown solution. According to the results the egg that was in the distilled water solution gained weight because it is the hypertonic solution. All the other eggs lost weight because they were placed in hypotonic solutions with different concentrations of sucrose. The egg that was placed in the higher concentration of sucrose lost the most weight. So, the higher the concentration of sucrose, the more water the egg lost.

It is usually a challenge to choose between the devil and the deep blue sea. Ordinarily, one has to consider one’s values as well as preferred consequences in order to make the better or best choice. In the short story, “What of This Goldfish, Would You Wish?” by Etgar Keret, Sergei Goralick faced a similar conundrum. As an aloof Russian expatriate fisherman in Jaffa, Israel, his only company is a magic three wish-granting fish. But having impulsively murdered Yonatan, Goralick had to decide whether to use his last wish to save the boy or keep his magic goldfish companion. Though he would have preferred the latter, Goralick made the better choice saving Yonatan as it matches his established humaneness and the consequences attached were more reasonable.

The reasoning behind this experiment is the examine whether the rate of osmosis is changed due to a change in temperature. It was hypothesized that the rate of osmosis will increase as the temperature of the sucrose is increased. The rate of osmosis was tested by using the different jars full of different temperate water and testing how high the water rose on an osmometer over a span of 20 minutes. An osmometer is a tool used to measure rates of osmosis. The different temperatures tested on a sucrose solution were 5 degrees Celsius, 20 degrees Celsius, and 37 degrees Celsius. Rates of osmosis were higher in the hot water than in the cold water and control. The results showed that the rate of osmosis increased as the temperature increased, henceforth the hypothesis was supported. In conclusion, the experiment showed how changes in temperature affect the rate of osmosis.

The principal objective of this study was to determine how temperature affects the activity of

If the temperature is too hot or too cold, then the reactivity and reaction rate of which the enzyme catalase breaks down hydrogen peroxide will decrease.

The solid water was the control variable in the experiment and the investigators compared values that resulted from irradiation of the solid water with each bolus’ average Dmax. Table 1 recorded the ratios that resulted from these values. ANOVA calculations from the values shown in Table 1 resulted in an F value of 762.65 and a P value of less than 0.0001. The investigator compared the results between each individual group with a Tukey HSD test. When compared to one another, each sample resulted in a P value less than 0.01.

It was demonstrated in animal studies that moderate (34°C) or mild (36°C) hypothermia improved neurologic outcomes.4 The mechanism for this effect is

Different species have different temperature and pH tolerances, but some of them, like the Amano shrimp, tolerate cool water very well. The

Animals exist either as very simple, or complex forms. Simple forms can either be unicellular such as bacteria, or simple multi-cellular, as flatworms and cnidarians. Complex animals are multi-cellular with organised organ system requirements that enable them to carry out complex metabolic processes. Respiration is one of the key metabolic processes for the energy requirements of all other physiologic processes. The primary role of respiration is to deliver oxygen to cells and tissues, and remove carbon dioxide (Charles, 2015) To appreciate how the size of organisms plays different roles in the respiratory process, we can use an example of a simple, multi-cellular organism like Planaria; a fresh-water, free-living flatworm, and compare with a complex multi-cellular organism like human.
