It is generally known that people can be more aggressive when they are not being watched by anyone or anything. This can

Which of the following is not an expected response in a fish to a drop in water temperature?

The Effect of Varying Temperatures on the Gill Movement of Carassius Auratus Overview: This lab was conducted with the purpose of confirming the trait of homeostasis among goldfish. During the experiment, it was recorded that the fish would increase gill movement when placed in colder water two out of the three trials. However, the results showed no significant difference in gill movement in various temperatures of water. This has very little effect on the broad field of science since our only three trials were performed and may have included human error in the trials.

3. What would your experimental approach be to test this hypothesis? - To test this hypothesis my experimental approach would be testing different bodies of water or testing one and just testing different areas while tracking the fish.

The results of the study found that there was a significant difference in Daphnia’s response when exposed to a cold stimulus in the form of crushed ice, compared to room temperature water. Thus, the null hypothesis was rejected and the alternate hypothesis was accepted. These findings could be due to

AbstractIn this paper will discuss the sexual selection theory and gender role theory. Then, what are the main principles of each theory? Additionally, what position is taken by each theory on the origins, development, and causal mechanisms of aggression? Moreover, give an example of aggressive behavior that may be explained from the perspective of sexual selection and from the perspective of social role theory that is not covered in the reading. Furthermore, discuss at least on psychological phenomenon that may influence displays of aggressive behavior as explained by the sexual selection theory and the social role theory.

Evolutionary history effects more than just genetic behaviour level. It also effects how society socializes its members. Males –despite having the innate behaviors and perspectives on relationships— experience socialization that, in essence, reinforces gender differences in perspectives and behavior. From early childhood up until adulthood, the individual is bombarded with a plethora of advertisments that portray males as more aggressive (Henslin p. 78). In television male newscasters turn female athletes into sexual objects (78). And socialization is not limited to the media. It begins in the home –within the family. In an experiment performed by Goldberg and Lewis, Mothers were more less likely to keep their boys

BIOL 152-35 Professor Weller 14 February 2012 Effects of Temperature on Goldfish Respiration Introduction This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process

Blue belongs to the bright colored fish species commonly known as betta or also as the Siamese fighting fish. Originally from Southeast Asia, this particular species of fish is known as a labyrinth because it is able to breathe in oxygen directly from the surface. In addition it can

Dolphins are highly social animals that travel in schools. It makes sense that they would sometimes forage as a cooperative group. Several species have been observed to be group foragers. Some of these species include spotted dolphins, Clymene dolphins, and bottlenose dolphins. The species most associated with group foraging has

Because males tend to value influential goals such as status among peers, they will typically use overt forms of aggression and gradually incorporate relational forms (Grotpeter & Crick, 1996). The choice of aggression could be linked to the social roles of males and females, the verbal maturity, or the social dynamics in peer relationships.

Male dominance A biology based theory on competitiveness is the ‘male dominance theory’. Developer of this theory, Steven Goldberg, presents in his book why the biological difference between men and women leads to ‘male domination’ (1993). This biological difference is mainly based to be found the difference in testosterone levels between men and women (Goldberg, 1993: 131). The level of testosterone would result in men having greater tendencies to be aggressive and a drive to dominate others. This ‘aggressive advantage’ would men also make more competitive and self –assertive. In combination this leads to men being more elicited to be dominant on average than women on average.

Although environment does play an important role in the formation and development of gender roles, it is not the only influence of gender roles. Biology also plays an important part in the determination of gender roles. In 1978, Braggio et al gathered data on the topic of cross specie observational study on the comparisons of the behavior of children, juvenile chimpanzees, and juvenile orangutans (Jarvis 269). The results showed a consistency of males performing a higher R&T (physically vigorous sets of behavior such as chase, jump and play fight (Jarvis 268)) frequency across all three species. The researchers argue that this is caused by hormonal determinism in the two genders. Whatson and Stirling (1992) concluded that those male infants across three species commonly possess a source of testosterone, which exerts an organizing effect upon behavior (Jarvis 269).

During this projects it was tested to see how each fish would react to the water. Most of the fish in the dirty water have died, all but 2. More of the fish died in this tank then the normal water tank.

Naked Eye and Inner Eye of Bishop From the perspective of a normal person with penetrating perception and description instead of omniscient point of view (or God), the poetry of Elisabeth Bishop tend to allow the truth drift itself with seemingly natural expression. There
