The Size And Its Effect On The Environment

3. Thermal springs, such as Old Faithful in Yellowstone National Park, have temperatures above 100°C. How does adaptation make it possible for living organisms to inhabit such an extreme environment?

Temperature and environment plays a key role on the effects of an ectothermic organism’s metabolism. The specific ectothermic organism used in this study was the Gromphadorhina portentosa also known as the Madagascar Hissing Cockroach. In this study we measured CO2 production (%) and temperature (̊C) every three minutes for a total of 15 minutes in three different temperature environments. The three temperature environments conducted in the experiment included room temperature, a cold environment (ice bath), and a hot environment (how water bath). The purpose of this study was to test the effects of temperature change on

Because of this, many possible sources of error in the experiment have to do with water temperature changing. One possible source of error was that the water surrounding the Daphnia magna was constantly returning to room temperature. Once the 30° C water was taken off the hot plate and put in the dish, it was always cooling down to reach room temperature, 21° C, by losing heat to the air. So that the heart rate found during the three different trials may have been at varying temperatures, some cooler than 30° C. Once the 10° C water was put in the dish, it was always warming up to reach room temperature, by gaining heat from the air. This may have caused the heart rate that was found during the three different trials to have been at varying temperatures, some warmer than 10°

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)

13. The temperature of the water was measured prior to the tube being placed in it and the temperature of the Hydrochloric Acid was measured after it 's temperature had adjusted.

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

Ectotherms like Gryllus (Niehaus 2012), commonly known as crickets, instead depend on external sources for their body heat. Ectotherms must use the environmental energy and behavioral adaptations to shift their body temperature. The basal metabolic rate (BMR) is a measure of the rate at which an organism releases heat after breaking down food molecules. Crickets possess the ability to respond to thermal change by

We have noticed in other experiments that smaller animals have a higher surface-to-volume (SA/V) ratios than larger animals with a lower SA/V. After reviewing through articles, we hypothesized that endotherms with small bodies will have a higher metabolic rate than endotherms with large bodies. We tested this by making 6 clay cubes (different sizes) and placed them in ice for 10 minutes and measured them in 2-minute intervals. Our results supported our hypothesis because the larger clay with the smallest SA/V had the slowest cooling rate while the smallest cube with the higher SA/V had the fastest cooling rate.

2. Some of the outside variables that could have affected our outcomes for the experiment are the ambient temperature and how quickly the groups took the hot dogs out of the ice water to measure their temperatures. The ambient temperature was 28 degrees Celsius, the coldest temperatures of the hot dogs ranged from 35 to 37 degrees Celsius, so for the groups that measured their hot dogs’ temperature quicker, they gave their hot dogs a head start in the warming process. For groups that were not as quick with their measurements, their hot dogs starting warming up at a later time, so by the time the experiment was over, their temperatures would have been lower than the groups that measured quickly. We did not control these outside variables because we did not increase or decrease the room temperature by turning on the AC.

The room temperature was measured throughout the lab and kept constant at 24°C (+/- 1°C), as the lab was conducted during the same time of

Somewhat more precise descriptions can be made by using the terms poikilothermic and homoiothermic. The body temperature of poikllotherms is relatively variable, while that of homeotherms is relatively constant.

The purpose for this was so we could have a control group in our experiment. Next, we put each test tube in a different temperature ranging from ice water to boiling water. After completing this, we put test tubes one through four in the water bath that was at body temperature, thirty seven degrees Celsius. We then took them out to see if they were runny and if so, put them back in the water bath for ten minutes. After observing the test tubes the first time, only one test tube was completely solid.

The Effect of Temperature on Animal Respiration Renee King 001420538 TA: Oliver Biology 3U03 L01 This lab examined the effect of temperature on the rate of oxygen consumption by measuring VO2. Effects were observed in goldfish, frogs, and mice, which each use different mechanisms for thermoregulation. The average rate of oxygen consumption by goldfish increased from an average of 0.175 mL g-1 h-1 at 5֯ C to 0.288 mL g-1 h-1 at 25 ֯C which was a 64% increase. The average rate of oxygen consumption by the frog was higher at 5֯ C than at 25 ֯C. At both temperatures, the rate of oxygen consumption increased over time.

I can vividly remember the moment when I was about to pull the paper towel in the restroom at Cerritos to dry my hands when I recalled the commitment that I had made just a while ago to lessen my use of paper products. Paper products greatly affect the forests increasing the rate of deforestation - conversion of forested regions into a non-forest land for human use and industrial benefits. After a long stare at the mirror, I smirked to myself and turned around, settling my wet hands in my pant’s pocket to let them dry till I reached my class. Although this commitment might just be like a drop of water in a vast ocean, my first effort towards progress is certainly valuable as progress has to begin from somewhere and through someone. Similarly, I have decided to recycle my books and to prioritize purchasing recycled materials as much as possible. Carrying handkerchief instead of using paper towel is another action that I have decided to take. Alongside that, I have also managed to convince my friends to reduce the use of forest resource products and are now clearly aware of the consequences of deforestation. Well-known yet an ignored issue regarding deforestation and it’s effects and it’s need to be controlled in order to maintain a livable environment for all of us convinced me to take a step towards change.
