Madagascar hissing cockroaches (Gromphadorhina portentosa) were the ectotherms used to compare standard metabolic rates and mass specific metabolic rates between organisms. To calculate metabolic rates for these individuals a system comprised of many parts was needed. A gas pump was needed to deliver airflow into the system. This gas pump was connected to a flow meter that could detect the flow rate of the gas passing through. The air would then flow into a Ascarite Column that would scrub out the CO2 from the system before the animal chamber was reached so that no CO2 that was not emitted by the animal would be collected. Then the Madagascar hissing cockroach would be in the animal chamber connected to the Ascarite Column and it would …show more content…
That CO2 and water vapor would then flow into a condensing ice bath that would cool the water vapor to condense it and remove it from the system. The CO2 and water would also pass through a Drierite Column to ensure that all excess water was removed before the airflow finally reached the CO2 analyzer was not wet. This CO2 analyzer then determines how much CO2 is in the air and sends that information to a computer with the Logger Pro 3 application to display all of the data that was received from the apparatus that was created. The application takes in flow rate data, temperature data, and CO2 in parts per million data. The weigh in grams, the sex, the amount of CO2 in ppm, and the status of habituation of the cockroach were recorded. Flow rate and temperature were also recorded and relatively consistent. A graph with metabolic rate (ml CO2 per min) on the y-axis and the groups of male and female for habituated and unhabituated cockroaches would go along the x-axis to help visualize the differences between the groups. An Analysis of Variance test (ANOVA) would be conducted by calculating the means of each group and with that calculating the sum of squares within groups, sum of squares between groups, and the total
We observed Sowbugs in multiple environments to determine which environment they preferred. The observational chamber was a rectangle box split equally in half. One side of this rectangle was filled with dry sand that had been heated for five minutes by a lamp, and the other side was filled with damp soil that did not receive the lamp heat. We placed each sowbug on the middle boarder of the cool, damp soil and the hot, dry sand. We each chose one sowbug to track, and made a record of its placement each minute for five minutes total. We repeated this process three times. After each repetition, we removed the sowbugs, and replaced them with new sowbugs to observe. After this observation, we shared, and recorded our results. The sowbugs spent
In the lab the isopods were observed in a way to where behavior and structures could be properly recorded. The isopods were revealed to two dissimilar scenarios, normal temperature water vs. warm temperature water, to calculate which environment was most preferred. In each distinct scenario ten isopods were placed ten a choice chamber, one side being normal temperature (26.7celsius) and the other being warm temperature (43.3 celsius) , and observed for a total of ten minutes with thirty second intervals which was when we recorded our observations. After observations, it was seen that normal conditions was the most preferred environment by the isopods. In the scenario the Isopods exhibited taxis behavior, which is behavior caused by factors such as light, temperature, water and such. Nothing physical, but rather environmental.

The Effect of Gas Exchange on a Locusts' Breathing Aim- To see the effect of Carbon dioxide on a locusts' ventilation rate. Method- Since the locust was already in the 20cm³ plastic syringe held in a clamp, our first step was to monitor its ventilation movements. By looking at the abdomen, we could clearly see the ventilation movements of the locust, which we counted for thirty seconds. We repeated this three times under normal atmospheric conditions.
In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase as the outside environment temperature will increase. I also predict that the metabolic rate in the endotherm will remain relatively the same as the outside environment temperature changes. I also make the prediction that the ectotherm will have much lower metabolic rates than the endotherm.
Who are the cockroach people? In basic words, they are the Chicanas and Chicanos, the Mexican-American race. They are the general population that do not belong anywhere but also belong to two different races, which are Mexico and America. They are considered the pariahs of both countries; it is possible that they are to white for Mexico or to Mexican for America. The novel, The Revolt of the Cockroach People by Oscar Zeta Acosta, is a captivating story of a Chicano lawyer named Buffalo Zeta Brown and every one of his hardships. He recounts the story of the Chicano individuals from his own experience, deliberately using dialect to highlight his outrage and energy for political injustices. Alongside dialect, Acosta additionally uses symbols
The use of this check is to uncover whether or not an organism is capable of exercising citrate as a carbon source. Position a needle of your organism along the surface of the slant. Next, start from the bottom and work your way up with the needle. The indicator that is already in the media is Bromothymol blue. An increase in PH will generate a bright blue for a positive result. The control is E.
There were approximately 8x the amount of pillbugs on the water side compared on the vinegar side. Many sources of error could have occurred during the experiment, however. One possible source of error was that about half of the pillbugs were actually sowbugs, an isopod crustacean that has extremely close relations with the the pillbug. The main difference is that sowbugs do not roll up. This could have been a source of error because the difference in the two species may have attributed to the preferences of the isopods in the experiment. A second possible source of error was uneven lighting on our experiment. We gave our best effort to control the lighting and background as much as possible so that the experiment would not be affected, but there could have been something that was overlooked because a classroom environment is not the easiest thing to control. The last source of error was something that could not have been avoided. As time goes on, the pillbugs could have slowed down their movements compared to when they were first dropped into the bin due to their natural

Forensic entomology is the learning of all types of insects and how they connect with criminal investigation. Forensic entomology can tell us how long since the offspring’s death which is known as postmortem interval (PMI) and whether the body has been relocated since putting one foot in the grave, and what injuries it may have suffered. At the start of decomposition, insects launch a new community by hatching eggs on the remains; the eggs will emerge into cankers (larvae) that will graze upon the human organs and tissues. A Forensic entomologists can figure out what specific bugs are presently in the body and gauge how long the body has been left unprotected by investigating how far along the cankers have come; although, what is found isn’t
Throughout time, the Jewish people had been discriminated, oppressed, mistreated, and even killed way before the Nazi era. From Christ-killers to being the devil, the Jews were never truly accepted anywhere. When Hitler came around, his hatred towards the Jews and other minorities went in crescendo. First using “legal” actions to repress and signal out the Jews in Germany, then measures got worse by the second. Right before Germany invaded Poland in 1939, the Jews were banned from every aspect of German life, social, religious, economic, etc. Unfortunately, from 1939 through 1941, the German Wehrmacht having tremendous success, their new weapons and tactics such as the Blitzkrieg caught their enemies by surprise. As a result, more than six millions of Jews were now under the control of the Nazi
This source provides relevant information to the topic at hand. It (the source) was used to examine the origin as well as the sources of Carbon Dioxide and obtain a clear understanding of what sort of an impact it can have on the environment. Although not all of the information in the source was used because of its indirect relevance, a great amount of background information was given in order to make the subject of Carbon Dioxide clearer and easier to understand. It does not state a for or against argument but rather serves as an excellent source of factual information.
Mosquitoes have been a major annoyance to humans for the millions of years of our developing ecosystems throughout the world, and they will be until we do something about them. But should we really do something to get rid of them? The common use of insecticides and pesticides is much too dangerous to use on the entire planet, and we really don’t know enough about the mosquitoes to get rid of them. What is the purpose of the mosquito? What could happen to the human race if we continue to use insecticides? What would happen to the global ecosystem if we rid of mosquitoes? Humans don’t always think major, environment-affecting decisions like these all the way through, which is why mosquitoes should be kept alive for the sake of the ecosystems of the world, and especially for humans.
The two columns in the graph represent the mean values and the error lines represent the standard deviations of the tested grasshopper and human subject. The jumping distance of the grasshoppers was more than the jumping distance of humans and the TTEST value was less than 0.05.
Ultimately when conducting this experiment I need to look at how to determine chemical change and how to measure
