Respiration Rate In Crickets

The purpose of this experiment was to measure the metabolic rate of pill bugs and crickets. I indirectly measured the metabolic rate of each organism by calculating their respiration rates. In crickets, gas exchange is accomplished via a tracheal system [Contreras, Bradley, 2010]. Pill bugs have pleopods, gill-like respiratory organs [Gibbs, Smigel, 2008]. My hypothesis was that the crickets will have a faster respiration rate than the pill bugs. I used a respirometer to measure the oxygen consumption of pill bugs and crickets. After plotting the data, I used the slope to obtain the respiration rate. The respiration rate per gram of organism for the pill bugs was 0.0025 mL/min./g. The respiration rate per gram of organism

The last condition tested was the hot environment in a hot bath. The cockroach was left undisturbed for three minutes to let it settle and then the time for collection started at minute zero. The CO2 (%) and temperature (̊C) was collected every three minutes for a total of fifteen minutes. After the fifteen minutes was up the cockroach was allowed time to recover for

This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms, whether it is given or released through that organism. Both plants and animals use oxygen and carbon dioxide for cellular respiration, giving off carbon dioxide as a waste product. This lab is an example of cellular respiration in both plants and animals. The change in the carbon dioxide levels will be

”The grasshopper and the bell cricket” is a short story, written by Yasunari Kawabata, written in a narrative perspective of someone watching children searching for insects using colored and decorated lanterns. I would like to think that the author is trying to symbolize life, and that it is not only one path to go. We are all aiming for acceptance and to fit in to the society, but this story tells us that

Cellular respiration is bioenergetic process, meaning that it is governed by enzyme activity. Referring to what was previously learned about enzymes, it is known that enzyme-substrate reactions can

During this experiment, sugar sources were varied and respiration rate evaluated. To begin, a water bath was set at 30 degrees Celsius. This creates an optimum temperature for the enzymes in yeast to breakdown sugar and give off CO₂. Each sugar source, glucose, sucrose, lactose and glycerol were all added to its own unique yeast sample, one at a time. Each sugar source that was added to the yeast solution was immediately incubated for 10 min, then was transferred to a respiration chamber. The CO₂ sensor was put in, recording the CO₂ respiration for 4 min. This process was done for each sugar source. The reparation rate was recorded through Logger Pro. After 4 min passed, the slope was recorded, resulting in respiration rate.

White-nose syndrome is a disorder connected to exceptional bat transience event in several areas of North America. In the study conducted by Blehert et al (2009), bats declines beyond 75% from winter 2006 to 2007. The fungal growths on their muzzles, ears, and/or wing membranes of the bats, cause them to collapse (Blehert et al. 2009). Thus, this experiment was done as research methods for inhibiting the growth, investigating factors affect the growth and to prevent the growth of the tip.

In insect species with indirect sperm transfer, sperm is packed in a spermatophore that is either externally attached to the female 's genital opening or introduced into her bursa copulatrix. Sperm transfer is not immediate in these species, and consequently mate guarding has been suggested to function as a mechanism of guarding sperm until it is released from the spermatophore into the female (i.e. spermatophore guarding). Spermatophore guarding is relatively common in insect species with external spermatophores (e.g. Orthoptera; Alcock 1994; Simmons 2001), but supposedly absent in species with internal spermatophores and rapid sperm release (Simmons 2001). This study focuses on two hypothesis associated with mate guarding a tactic of many species that adjust their reproductive behaviour according to the apparent risk of sperm competition. The phenomenon of mate guard to consider sperm competition levels and evolution of internal spermatophore guard is wide spread in insects and other animals. We analyse two hypothesis one the rival exclusion followed by the next spermatophore renewal hypothesis. Results showed that as rival was introduced to the arena of mating of the distinctive original male (guard) in many cases showed a strong aggressive behaviour regardless of whether successively avert the rival. In the second hypothesis certainly majority of the incidents showed an attempt of

At the end of 60 minutes, test tube 1 ,2, 3, 4, 5 and 6 produced 47 mm, 33 mm, 4 mm, 4 mm, 9 mm and 46 mm of CO2, respectively. The amount of CO2 produced tells us that there was a high rate of cellular respiration in test tube 1, 2 and 6 and there was a low rate in test tube 3, 4 and 5. As shown on the graph, there is a steeper slope for test tube 1, 2 and 6 and gentle slope for test tube 3, 4, and 5. The steeper the slope the faster the rate of CO2 produced. The test tubes 1, 2 and 6 had high rate of respiration because of the presence of glucose, maltose and MgSO4, respectively. Both glucose and maltose is able to give more amount of CO2 than any other substrate. MgSO4 is a cofactor and the presence of the cofactor allows better formation of pyruvates resulting in a higher rate of cellular respiration. The test tube 4 had a low rate because it contained no substrate for respiration, there was only water. There was a low rate in test tube 5 because of the presence of NaF. NaF is an inhibitor and have the capacity to interfere with the enzymatic activity. The presence of alanine will result in low rate of cellular respiration as seen on test tube 3 because alanine has least amount of carbon in

The CO2 production was measured with a CO2 meter (+/- 1ppm), in order to determine the rate of anaerobic cell respiration in yeast.

The investigation is of the standard metabolic rate of the Madagascar hissing cockroaches (Gromphadprhina portentosa), with a difference of temperatures between two tests and if effect of the temperature changes the standard metabolic rate (SMR) of the cockroaches. The experiment was designed to determine if the SMR of the cockroaches would change based upon whether they were surrounded by different temperatures in their environment. The definition a SMR is the lowest metabolic rate required for the survival of an organism. It is measured when the organism is resting. Metabolic rates are expressed micro moles of carbon dioxide produced per sec (μmol CO2/sec) and CO2 produced per individual milligram of tissue per second (μmol CO2/mg/sec) (Hadow et al. 2015). The measurements of metabolic rates are taken because it plays a key role in different types of physiology, providing energy required to continue with growth and reproduction measured through qualitative and quantitative data, and an ecological role in which the metabolic rate affects territory preferences and foraging behaviors of the animal (Hadow et al. 2015).

After observation, the cotton ball was switched to the other end with cinnamon on it.

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.

Intro: This experiment introduced experimentation on animal behavior, and explored the responses of crickets to environment. For our lab, we tested whether crickets would prefer a warm, dry environment, or a refrigerated, moist environment. We hypothesized that the cricket would rather be in the dry environment when provided the choice. To create these environments, we combined two petri dishes: one was barren and put in the sunlight, the other was in the shade, and refrigerated with two ice packs. One ice pack on the top and the other on the bottom. The former petri dish was based on their environment as observed in nature. According to the University of Arizona, crickets prefer to live “under rocks and logs in meadows, pastures and along

Rate of Respiration in Yeast Aim: I am going to investigate the rate of respiration of yeast cells in the presence of two different sugar solutions: glucose, sucrose. I will examine the two solutions seeing which one makes the yeast respire faster. I will be able to tell which sugar solution is faster at making the yeast respire by counting the number of bubbles passed through 20cm of water after the yeast and glucose solutions have been mixed. Prediction: I predict that the glucose solution will provide the yeast with a better medium by which it will produce a faster rate of respiration.
