Pill Bugs And Crickets Lab Report

This study was undertaken in order to compare the 〖CO〗_2 output of a cricket (Acheta domesticus) as a way to indirectly measure its respiration. This was done by observing the 〖CO〗_2 output of a cricket (μL/min⁡) over different levels of DNP, 2,4-Dinitrophenol. It was shown that the crickets subject to DNP (n=10) had a significantly higher 〖CO〗_2 production rate (p= 7.4e-10) than the control crickets(n=10), that were not exposed to DNP. This indicates that the presence of DNP induced a greater of respiration rate in crickets. There may be several factors that contributed to these results such as the cricket’s physical size and its health conditions. These factors vary between individuals and may affect the degree of respiration. A better insight

The important procedures of this experiment was to observe the pill bugs and determine whether they prefer a certain environment over another. The results and data of the lab show and prove that the isopods prefered the room temperature environment over the warm environment. The hypothesis is accepted because it states that if the isopods were given a choice of a room temperature environment or a warm environment, the isopods will choose the room temperature environment, and the isopods chose the room temperature environment. The control of this experiment was the room temperature chamber.

The Pill Bug Lab created many various trends or patterns in the data. The data in figure 2 show that towards the beginning of the experiment, the pill bugs were very active in both the wet and dry environments. This is because the Pill Bugs were suddenly placed in an environment they had not been in before, so there first reaction was to find a place of comfort to settle in. Over time, which figure 1 shows, many pill bugs switched from one location to another and continued to move back and forth. As the experiment was coming to an end, the data shows that the pill bugs slowly started to settle into their final destination.

The pill bugs were moving more in hot environment than cold temperature and room temperature. The pill bugs made more turning in room temperature than cold and hot environment. The pill bugs made more rounds in room temperature than cold and hot environment. The hypothesis was that pill bugs will react more in moisture or humid environment that others. Based on our result, the hypothesis will be rejected. The reason why the result was not accurate can be due to limitation or errors during the experiment. The fact that the same pill bugs were used for the three trials can be considered as an error because bugs might be tired after the first trial. In future the experiment, different bugs should be used in each trial. Another error can be the condensation that occurred during the heating process. A wet paper was placed in the Petri dish. During the heating process, the water evaporated and since the petri dish was covered with led, the vapor is transformed to water, however, pill bugs do not live in water. In the future experiment, the petri dish should be kept open to avoid the

Why do organisms respond to environmental factors? Organisms keep themselves in the most favorable conditions in order to survive. Pill bugs are members of the terrestrial isopod family. Terrestrial Isopods retrieve oxygen through their gills and live in dark damp environments. These organisms eat decaying plant and animal matter. Sow bugs, also known as pill bugs were tested to see how they react or respond to environmental factors. In this lab two different experiments were conducted. During the first experiment pill bugs were tested to see if they prefer a light environment or a dark environment. Throughout second experiment the pill bugs were tested to see how many of the bugs prefer an environment with vinegar or environment

The results presented show that pill bugs or “rolly pollies” took a more favorable liking to water then the “X” substance, starch. Three trials were held inside two attached petri dishes one containing water while the other had starch with all pill bugs starting at a neutral inner circle in between. Observing trial one, six pill bugs advanced to the water soaked petri dish while the other six pill bugs occupied the starch soaked petri dish. In trial two three pill bugs left the starch soaked petri dish and 6 pill bugs still remained with water. Lastly in trial three, nine out of the twelve pill bugs resided in the starch petri dish while the other three stayed in the water soaked petri dish. Two of these three tests support the hypothesis that

We put equal amounts of sand or dirt in each chamber, as well as 6 mL of water mixed in on either side. Afterwards, we placed 12 pill bugs in the bridge between the dishes. This allows the pill bugs a clear choice between the two materials. We recorded the number of pill bugs on the dirt dish, sand dish, and bridge each minute for seven minutes in a chart. We did this to indicate any movement the pill bugs might have performed during the experiment.

Pillbugs (Armadillidiidae) live in moist environments outdoors and usually found under rocks or dark places like crevices. They often bury themselves several inches beneath the soil surface to avoid hot, dry conditions (Merchant 2017). Another frequent hiding place is behind the grass edge adjoining sidewalks and foundations (Potter 2017). Although they sometimes enter in large numbers, they do not bite, sting, or transmit diseases, nor do they infest food, clothing or wood. They are simply a nuisance by their presence (Potter 2017). Pill Bugs feed mostly on decaying animals and plants as their main source of food but sometimes they feed on young plants. If they do eat young plants it does not have any significant impact on the bug. If they

Pill bugs since related with the isopods their water misfortune can be associated through dissipation of the pleopods, which is their gills. This impacts the survival factor and in addition the appropriation. Pill bugs are an uncommon sort of isopod, their logical name is Armadillidiidae. They are exceptional contrasted with other earthbound isopod on the grounds that their exoskeleton can move up into a ball known as conglobation. This procedure backs off the rate of water misfortune making it less demanding for these pill bugs to survive contrasted with others. A trial was led with these bugs to test the conglobation theory that it moderates the rate of water misfortune, and they ensured that the bugs chose in the investigation would be generally

No vial was put upright since sleeping flies would fall on the food and die thus the vials were put on their sides. The vials were store in the light and at a temperature of 25 Celsius to 25 Celsius for a week since warmer temperature shorted the generation time and colder temperature resulted in top a longer generation time. The temperature was recorded and in the Result

The reason for their name Pill bugs is that when they roll into a small ball, they look like a pill. Their pereonites structure helps them roll away to protect themselves from predators. Since they have gills, they must live in a damp moist place in order to breathe to survive. They can be found in gardens, meadows, and in basements. They are considered pests to gardeners but they rarely do any harm if they are being a small colony.

To make the graph and data table, the students used three types of results from the experiment: Class average, which was the average respiration rate for each carbohydrate from one biology class. Overall average, which was the respiration rate for each carbohydrate for each group in all of the biology classes. The individual groups data. The individual group data for glucose was 4.655 (ppm/min), sucrose: 754.06 (ppm/min), lactose: 276.54 (ppm/min), and starch: 351.28 (ppm/min).

Metabolic rate depends on body size, the small-bodied species tend to have a higher weight-specific metabolic rate than lager. According to the data and graphing shows above that the new species have a smaller body size than previous species which proves the new species tend to have a higher metabolic rate than previous species. The high metabolic rate might lead to the new species having a shorter lifespan than previous species.

In otherwords, the oxygen demand for the cell cannot be met, unless the insect was to evolve its’ shape to increase surface area by being flattened (like the waterbug example) or lower the demand by becoming slow moving (exercise/increased muscular movement increases the rate of gas exchange occurring as cells

The hypothesis we had was that the mass of the insect correlates towards respiration. The more mass it has the higher respiration. The dependent variable is the mass of the
