Morgan Billick September 4th‚ 2010 Ventilation and Oxygen Consumption Results Oxygen Concentration Oxygen concentration in water can be altered by the conditions it is exposed to. For instance cold water has a higher oxygen concentration than warm water. In our experiment we were able to observe the change in oxygen concentration of water at two different temperatures (15C and 25C) with a fish in each environment. Our results proved that the starting oxygen concentration of the cold water was

INTRODUCTION Goldfish (Carassius auratus) are ectothermic (cold-blooded) animals. This means that their body temperature changes with the change in the environmental temperature. When there is a low water temperature a fish slows down and so do its metabolic activities and when water temperatures are high‚ fish speed up and their metabolic processes increase as well. Proteins and enzymes are also affected by temperature changes. Oxygen is essential for the production of ATP from nutrients
Premium Metabolism Temperature
goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus ambient

Ventilation and Oxygen Consumption in Fish Sally Ming Bio 102- PR# 2 12/12/12 Abstract Goldfish (Carassius Autarus)‚ when subjected to warm temperatures will have a high rate of ventilation compared to those exposed in colder environment. In a class experiment‚ we observed and recorded the effects of water temperature at [25 C] warm and [15 C] cold on ventilation and consumption rates in goldfish. For one hour at 15min intervals we observed differences in both ventilation and consumption

Abstract: Maximal oxygen consumption (VO₂max) is an excellent indicator of a person’s physical fitness level. It can also be used for many other things including diagnostic tools for physicians. In this study‚ two different methods of collecting maximal oxygen uptake scores were compared. The first being the predicted VO₂max score attained via the Rockport test and the second being indirect calorimetry VO₂max score attained through cycle ergometer and an attached metabolic cart. Ten males and nine

VENTILATION QSB 1714 Prepared by: Mariatul Liza bt Meor Gheda Introduction Definition: The process of changing air in an enclosed space. A proportion of air within the enclosed space should be continuously withdrawn and replaced by fresh air. Drawn in from a clean external source: • At as high an elevation as practical…where more polluted air occurs at the relatively low levels found in congested towns and cities. Why do we need ventilation? Ventilation is needed

Chemistry is everywhere. It is even in the food we eat. Goldfish is a great example of chemistry in food. Pepperidge Farm is the manufacturer of Goldfish and they are located at 595 Westport Ave Norwalk‚ CT‚ 06851 United States. Goldfish were discovered in 1962 by a women who went to Switzerland. She returned to the states with the recipe for these cheddar crackers. Goldfish are a common snack loved by children everywhere. However‚ these children don’t realize that what they are eating has to do

THE GOLDFISH ELEONORE FARJEON There was once a Goldfish who lived in the sea in the days when all fishes lived there. He was perfectly happy‚ and had only one care; and that was to avoid the net that floated about in the water now here‚ now there. But all the fish had been warned by King Neptune‚ their father‚ to avoid the net‚ and in those days they did as they were bid. So the Goldfish enjoyed a glorious life‚ swimming for days and days in the blue and green water: sometimes low down close to

Bianca Barraza APES Per. 5 10-21-14 The Effects Of Dissolved Oxygen On Fish Background: The goldfish‚ or in other words the carassius auratus is a fish that has well-known by its bright gold color. Many goldfishes are able to absorb oxygen directly from the water into their bloodstream using their gills. Goldfishes and other marine life need dissolved oxygen‚ which is oxygen dissolved in water‚ and is necessary to many forms of life‚ including invertebrates‚ bacteria and plants. However‚ increased

create larger molecules. Respiration provides energy for these reactions‚ and respiration needs oxygen to occur. Thus‚ calculating the change in oxygen can determine metabolic rate (University‚ 59). In this experiment‚ we will observe and analyze the oxygen consumption of Carassius auratus‚ also known as goldfish. Oxygen depletion has proven to increase with the presence of caffeine (Womack). Goldfish are ideal species to further solidify this theory due to the fact that they are poikilothermic‚
