Isopod Lab Report

A two-part study was recently done to show what natural habitat a Pill bug, Armadillidium vulgare, naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment, a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light was hung above one chamber of another double-chambered petri dish while the other chamber was covered with aluminum foil, after placing soil in both chambers. An equal number of Pill bugs was placed in each chamber and a study was taken for

Begining by labeling 7 different 2.0 ml tubes 0 thru 6 for each compound. Then add 1ml of extract to tube 0. Then add 0.5 ml of DMSO to tubes 1 thru 6. Now make a 1:2 serial dilution from 0(pure extract) to 6(1:16)

The Panasonic Lumix DMC TS30 comes with a resolution of 16.10 Megapixels with a Sensor size of 1/2.33 inch. The Lens flaunts a 4.00x zoom (25-100mm eq) quality, enabling distant object to appear closer through the lens. With an ISO of 100-1600 and a Shutter speed of 60 (minimum) and 1/1300 (maximum), the Panasonic Camera comes with the dimensions of 4.1 x 2.3 x 0.8 in.(104 x 58 x 20 mm). the Camera weighs about 5.1 oz ((144 g)includes batteries).

Isopods are land dwelling crustaceans also known as pill bugs. In the lab the isopods will be studied on ethology which is the study of animal behavior. The taxis and kinesis will also be studied of the isopods. Taxis is when a certain factor attracts or repels an individual. Kinesis is when an individual randomly moves because of a certain factor.

The isopods used for this experiment range in color from gray to brown and were about 8.5 to 18 mm in length. Each Isopod’s head had one pair of antennae and one pair of antennules, both used to detect sensory stimuli from the environment around the pillbug. Their bodies were made of a hard thorax with seven segments and an abdomen. Each pillbug had seven pairs of legs, one for each segment of its thorax. Pill bugs breathe through gill-like structures and must live in moist places.

Rubisco is the most abundant protein on earth that is essential for carbon fixation in plants. For the protein to function at its optimal level, it needs to be isolated from the mixture of proteins and in its purest form. The three isolation techniques carried out in this lab are salting out, ion exchange chromatography, and SDS-PAGE. Rubisco will be purer as each technique is conducted and will be in its purest form after the last isolation technique is carried out.

1The isopods will gather in the wetter environment instead of the dry environment. 2The isopods will have an affinity to a more basic region than an acidic region. 3The isopods will tend to gather in the environment with a greater amount of light, than an environment with no light. 4The isopods will take a liking to a warmer temperature environment than a cooler temperature environment.By looking at the data you can see that there is a preference among isopods to favor an environment that is cold, wet, basic, and dark. We included the observed data as well as the expected data. Our expected data show what the information would look like if it came from a null universe. To come from a null universe means that the data will have no difference,

Pillbugs and sowbugs are terrestrial isopods that belong to the order Isopoda and the arthropod class crustacean. According to the Current Topics in Microbiology and Immunology, the terrestrial isopods have evolved from the marine forms. However despite the fact that they seek moist environments they must also avoid an overly moist environment (Journal of Insect Science, 2008). The two different species resemble one another phenotypically. However, pillbugs are a dark gray and the sow bugs are a light gray with posterior projections. Pillbugs also curl into a ball when they feel endangered and the sow bugs do not. The pill bugs used in this experiment were female. Isopods primarily live in dark, damp habitats in order to prevent dehydration (Isopod Behavior Lab). The purpose of this experiment was to determine the type of environment isopods prefer. First we tested to see if the isopods preferred a dry or moist environment and then we tested to see if they preferred the potting soil or the leaf litter environment. For the observation of isopods in response to moisture experiment it was said that each of the two different species would prefer a different environment. For part two, Observation of Isopods in response to other variables, it was hypothesized that the Isopods would prefer the potting soil or the leaf litter environment.

Conclusion: In our experiment, we were able to observe the isopods behavior. According to our hypothesis, it stated that if we divide the isopods equally in light and dark, carefully administered, the isopods will gravitate towards the darker side. The dependent variables were the isopods and their behavior whereas the independent variables were time, temperature and light. We conducted our experiment by collecting a total of 16 isopods in total and equally distributing them into two chambers that we had constructed. The chambers were made out of two water cups and one cardboard paper in the middle to make a bridge to allow isopods to move into the other side. The group used paper towels to make sure the bugs couldn't burrow beneath. In total we had 3 trials put

This Experiment aims to analyze the behaviour of the maggots in a particular temperature. Behaviour of the maggots is defined as the way they respond to their surrounding and environment. Maggots are organisms which react by quickly and a series of varied reflex reactions are shown and adapted. These kinds of actions are very important for keeping itself in a particular environment to live. Therefore, it would be expected that all maggots react in the same way to show a particular behavioural trend.

As a result of this lab experiment, the hypothesis is attested to be precise as the ionic compounds did go through a double displacement reaction. The purpose of this experiment was to establish what occurs when two pairs of compounds react with one another. The information collected while doing the lab has allowed more knowledge to be obtained, as one can visibly see the changes happening and different signs of chemical changes. The cations and anions in the ionic compounds have successfully exchanged places with one another, creating the compounds with the different properties evident in the observation given. For example, precipitates were visible in almost all reactions in this experiment. Therefore, this lab experiment was held to demonstrate

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Ideas Addressed Throughout the Lab. This Lab was able to observe the behavior of Isopods, and their preferences in environment. Isopods are one of the few land crustaceans, meaning most of their “relatives” would prefer wetland. The purpose of the experiment was to test if their preference would be the same, compared to their water counterparts. Hypothesis.

There are many patterns that can be observed throughout our environment. In this experiment, the temperatures of organisms in a biophysical environment were analyzed to see if a pattern could be recognized that was related to the behavior of an ectotherm. An ectotherm is an organism that relies on the environment to regulate its body temperature. Organisms such as Pseudemys (turtles) and Lacertilia (lizards) are examples or ectotherms. After arriving at Maxcy Gregg Park and analyzing the temperatures of four microhabitats within two habitats with infrared thermometers, the temperatures were compared between the microhabitats. Then, one habitat was chosen to analyze the temperatures between

The purpose of our experiment was to observe the behavior of the pill bugs. We were trying to find exactly whether the pill bugs would be attracted or repelled by the chemicals. The chemicals used were vinegar, water, salt solution and a sugar
