Abstract/Background:
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.
Problem:
In this observation, the purpose is to understand ethology, which is the study of how an animal’s

After results, it was concluded that isopods prefer normal temperature conditions over warm conditions. We created these environments by adding water onto filter papers with the accounted for temperature measurements. The reason for the results could be seen in a usual isopod environment, it is usually dark, fresh, and moist, and the normal water temperature being the closest to that was the reason for their choosing. The Isopods seemed to locate the appropriate environment by the use of their antennas. For the investigation the normal water and warm water temperatures were independent variables. The observations were the control. The isopods behavior served as the dependent variables. The isopod behavior would be classified as movement in response to a cooler temperature environment taxis. All in all the hypothesis, “If the isopods are exposed to normal and warm temperatures then the normal temperature will be preferred” proved to be
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
T. californicus is found from Alaska to Baja in small, shallow tidepools and tidal flats in the upper spray zone where they cannot avoid the full effect of visible and ultraviolet (UV) radiation. Individuals assemble in areas of lower radiation at midday, yet have no preference to the intensity of light at dawn and dusk (Hartline and Macmillan 1995). These tiny arthropods inhabit all types of marine sediments from sand to fine mud and ooze. Along with plankton, T. californicus eats microscopic algae, protists, bacteria, diatoms, algae and microbes (McGroarty 1958). When the concentrations of the species in their habitats are high, T. californicus will turn to cannibalism for a food source. The nautilus eye present in the species is rich with fatty acids and provides a good food source for the animal.
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.

The protozoan commonly known as the “water bear” is an extremophile that has engaged many in the scientific community. The Tardigrade is an invertebrate that has eight legs and comes in many shapes and sizes. This group has many adaptations such as cryptobiosis that allows it to survive in extreme environments. The Tardigrade can be found from land, to water, to sulfur springs, and to over 25 species found in the frozen tundra of Antarctica (Miller et al, 2001). To understand these creatures this paper will summarize the taxonomy, reproduction, food, and protective genetics, of the Tardigrades. The first section to this paper will examine is how these creatures are divided taxonomically.

The organism Daphnia magna belongs to the phylum Arthropoda, subphylum Crustacea, and the class Branchiopoda (Ebert, 2005). As planktonic organisms (National Science Teachers Association, 1987), Daphnia are found in “freshwater, temperate environments throughout North America” (National Science Teachers Association, 1987). The Daphnia also contains a pair of antenna located at the top of the head that is used as a method of movement (Ebert, 2005). Due to its transparency, the Daphnia is easily visible through a microscope. The nervous system of Daphnia is rather primitive, containing a cerebral ganglion (Ebert, 2005) which is a nerve cluster containing both afferent and efferent nerves (Chase, 2000). Most environmental changes affecting the
Animalism bases its conclusion on personal identity that the bodies must have the same material body. It fails to address the mind of the bodies at both time t and t*. Also, though the body stays qualitatively identical (same properties); it’s not numerical identical (same substance). Nevertheless, psychological continuity focuses on the mind of the person but not its body. It suggest that
The Chelonia mydas, also known as the Hawaiian green sea turtle, or as Honu here in Hawaii, have roamed the oceans for millions of years. Forty years ago this beautiful species was almost completely removed from this earth, but was saved by the U.S. endangered species act of 1973. These magnificent creatures can now be found in abundance in the coastal strand and open ocean biomes of the North shore in Oahu, Hawaii. The green sea turtles occupy different habitats such as; beaches for nesting, open ocean convergence zones and coastal areas for benthic feeding. Unlike other sea turtles, the Honu don’t only use the beaches for nesting, they use them for thermoregulation in the sun. These green sea turtles have behaviors and characteristics

To sum up, a huge number of Animals is used by people. They are consumed animals for many purposes to spend enjoyable time, and produce Egg, meat, leather, wool and hair. Animal farming sector, furthermore, is the main part of structural farming in worldwide or industrialised countries that they are currently supplying an enormous size and concentrate of infrastructure particular meat in the world. The expression of model animal welfare has some separate meanings in this issue that it is treating the enduring and stress of sensitive animals.
The comparative method is a species that can be studied and compared to the search of understanding human behavior. The physiological outlook elucidate the performance of how the nervous system and hormones reacts to the body, what precedent of the transformations in the structure can affect one’s behavior, and how the brain operates. For example, when a cardiologist operate on someone’s heart. He has the expectation of extending that individual's life (Thomas Spray). Another comparative method utilized is the investigation of inheritance. This technique engages a species inheriting genes from its parents. For instance, when the offspring with dark skin complexion begat blue eyes this trait is hereditary. Each of these biological aspects consisting of the comparative, physiological and the genetic systems explicates human behavior. This dissertation will focus on the brain, the nervous system, and the ways in which these physiological mechanisms interrelate.

Materials used for this experiment includes 8 plastic cups, 8 ziplock bags, and rubbing alcohol. The plastic cups and ziplock bags were numbered from one through 8. The cups were placed in two different habitats; four cups in each habitat. The first habitat was near a canal and the second habitat was under a tree. In the first habitat, a six-inch hole were dug and cup one was
