At the conclusion of the experiment, the two hypotheses were reviewed. Because the water temperature did affect the normal respiration patterns of the goldfish, the null hypothesis was disregarded and the alternative hypothesis was accepted. From the results of this experiment, it was concluded that although other environmental factors could play

Both temperature and chemical changes to the environment were observed to effect the daphnia’s heart rate. Increasing water temperature

The trend observed was as the volume of the flask decreased and the amount of oxygen consumption increased. This trend can be explained through the behavior of each zebrafish. When placed in a larger area, the zebrafish tended to be more relaxed and stationary, compared to the fish placed in a smaller area. Due to the stress brought on by the limited area, the fish reacted by rapidly moving around. As a result of the zebrafishes reaction to the space, there was an increased amount of oxygen consumed, compared to the fish who had no stress. The trend is justified from the difference in the initial oxygen within the closed system to the final amount of oxygen calculated at the

Metabolic rate is measured by the rate of oxygen consumption and oxygen consumption rate changes over time during the experiment. The crayfish acclimated to warm temperature increased the oxygen consumption whereas the crayfish acclimated to cold temperature decreased the oxygen consumption. In our experiment, there was no significant effect of acclimation temperature on oxygen consumption. The warm and cold-acclimated crayfish showed similar mean oxygen consumption rate despite different acclimation temperatures (Fig.1). Also, the P

Cellular respiration is the aerobic harvesting of energy from food molecule (Simon 2016). Energy is typically released after chemicals breakdown from sugar and starches, then converted to adenosine triphosphate (ATP). ATP is used as the energy source for cellular activity. Most of the reactions caused by cellular respiration happen in an organelle called the mitochondria, which also keeps the working cell full of energy. The purpose of cellular respiration is to provide the body with natural elements and provide oxygen which can stimulate growth. Cellular respiration also removes any toxic and wasteful nutrients from the body through carbon dioxide gas (CO2) and water. Cellular respiration is a byproduct of photosynthesis which both occurs in plants, but animals are the only host that experience only cellular respiration. This is because animals do not have the ability to produce their own energy. Therefore, herbivores receive their energy from eating a plant that performs photosynthesis and carnivores receive their energy from the other animals that eat plants. This process and more can all be simplified throughout the three stages of cellular respiration which begins with sugar, citric acid, and the importance of transporting electrons.

All living organisms respire. The energy produced by respiration is needed for organisms to carry out life processes in order to survive and reproduce. Gas exchange is the process by which oxygen enters and carbon dioxide simultaneously leaves the body, by diffusion across gas exchange surfaces. Oxygen is used in cellular respiration in the breakdown of glucose into ATP to give an organism energy for life processes. For gas exchange to occur, the gas exchange surface must have a large surface area to volume ratio, to be thin and have mechanisms for maintaining a steep concentration gradient across the gas exchange surface. Gas exchange surfaces must also be permeable to gases. Different types of organisms such as insects, fish and mammals have

The data received from the experiment displayed a p-value of 0.001, which was smaller than 0.05. Therefore, the null hypothesis was rejected. In other words, the data showed that the metabolic rate of gold fish changed after increasing environmental temperature. The metabolic rate of gold fish was measured by the change in Oxygen concentration consumed by gold fish per unit of time per weight of fish, which was delta [O2]/(hour*kg). The result of this study was significant because it contributed to a previous gold fish study. According to a gold fish study conducted by F. E. J. Fry and J. S. Hart, the cruising speed of gold fish was related to water temperature. More specifically, Fry and Hart concluded that as water temperature increased, the cruising speed of gold fish also increased until when the temperature became lethal to the fish (41-degree Celsius). Relating to Fry and Hart’s finding, this study suggested that gold fish’s behavior related to water temperature in either one out of two possible ways (Figure 1a and 1b). In the first case, as water temperature increased, gold fish received heat or energy from the environment, resulting in

This experiment consisted of 3 respirometers, one with ants, one with radish seeds, and one with glass beads. Each with 4 pellets of KOH and a piece of cotton. They were placed in a water bath that was at 75 degrees fahrenheit. A bubble at the end of the respirometer was measured every five minutes, and this distance showed how well the organisms were respiring. The radish seeds were able to do the most cellular respiration in 25 minutes, with the ants being a close second, and the control respirometer of the glass beads doing the least.

In order for cells to grow, divide, and stay active, they must have sufficient energy. This energy comes from the oxidation of organic molecules such as glucose in respiration. Respiration is a series of oxidation taking place in all living cells releasing energy from organic compounds such as glucose. All respiration involves oxidation reactions and therefore all cells must have a constant supply of oxygen. In order for this to happen the exchange of gases between respiring cells and the environment are required. Gas exchange is a process by which oxygen gets into cells and carbon dioxide is released. Respiration creates the constant demand for oxygen and a release of carbon dioxide.

All living organisms respire in order to survive. Respiration is the metabolic process of most living things that occurs in the mitochondria in which glucose is broken down into usable energy (ATP) for the cell. The energy that is formed through this process is the requirement for every living cell to assist with life processes in order for organisms to survive and produce. The main gases involved in aerobic respiration are oxygen and carbon dioxide. For respiration to take place in an organism, it requires the exchange of gases between the respiring cells and the environment. Gas exchange is a very important physical process that occurs in an organism in order for aerobic respiration to take place in that organism. In this process oxygen is

Fish also feel the effects of an acidic environment. An acidic environment changes the pH of the fish's’ blood, this condition is known as acidosis. Fish burn extra energy to eliminate spare acid out of its blood. This would leave the fish without energy to do things such as Growing, obtain food, digest food, reproduce, or escape from predators.

De-Boeck et al. (2000) reported that salt exposure reduced food intake by 70 % in common carp, Cyprinus carpio and had adverse effects on growth and survival. Although food consumption decreased and growth was seriously affected, routine oxygen consumption of the exposed fish did not drop, indicating a reallocation of energy expenditure from growth toward other processes.

Various physiological processes in fish regulate internal pH levels to compensate for acidifying environmental conditions, such as active bicarbonate accumulation (Fabry et al. 2008). These buffering processes can impact metabolic rates, growth rates, or fecundity in adult fish or become overwhelmed in early life-stage fish, causing mortality (Murray et al. 2014; Fabry et al. 2008). Responses are highly species-specific, and there is evidence that some estuarine fish can tolerate greater decreases in pH than pelagic species because they are often preadapted to daily fluctuations of pH (Murray et al. 2014). Early studies on the effects of acidified conditions on marine finfish used unrealistically low pH levels in order to identify the physiological responses (Fabry et al. 2008). Some recent studies have constrained pH levels in their experiments to those predicted in the coming century (Murray et al. 2014; Ishimatsu et al.

he safety precautions taken to avoid injury to the goldfish or students was Animal Safety, Sharp Object Safety, and Biological Safety. Multiple goldfish were dealt with therefore the students needed to handle them with care. The water the goldfish were in was very dirty and in glass. Therefore, it was necessary to be cautious of the glass which could hurt a person if dropped. Does the temperature of the water affect the breathing rate of the goldfish? The temperature of the water does affect the breathing rate of the goldfish. If the breathing rate of the goldfish is affected by the temperature of the water, then the goldfish’s breathing rate will speed up when the water is colder and slow down when it is warmer.

Students rarely contemplate the origin of the breath that passes through their respiratory system nearly every second of the day. Often, they also fail to envisage or appreciate the complex and intricate processes that facilitate the operation of our body’s functions through respiration. Numerous people often unconsciously remain in a state of digression when discussing the processes of energizing our own bodies and other imperative mediums, such as power and heat, in the world around us. Adulation for the sugars that expedite the preceding processes is certainly not lacking, but the coherence of another ingredient to respiration and the knowledge of its origins is often deficient. It is also essential to adumbrate that the producers of this ingredient are not particularly fervid about manufacturing it as it is simply a picayune by-product in the process of photosynthesis for plants. Surprisingly, this by-product is one of the most vital elements to animal life and is known simply as oxygen to the most juvenile or educated individuals. While the prominent products of photosynthesis-organic compounds called sugars-will eventually provide energy to all respiring organisms and numerous other inorganic sources, oxygen instigates the process; the chemical compound O2 is required to burn the carbohydrates, creating adenosine triphosphate (ATP), the source of energy for metabolism (Cogdell 3). Remarkably, the seemly nugatory organelles called chloroplasts are entirely responsible
