The Pill Bug Experiment

In this experiement, there were two behaviors kinesis, and taxis, our pillbugs showed taxis behavior in all four types of environments. Introduction: Ethology is the

In the second experiment our hypothesis stated that when the number of males placed in a dish are increased with a (sustained) amount of one female beetle, the time span of the mating process will decrease because the female will have of an option. This hypothesis was not supported because with the trials we preformed the results showed that the different ratio of dishes had a different time span of which they

Daphnia Magna are small crustaceans that are excellent for observing the effect of depressants on their nervous system. The purpose of this specific experiment is to observe the effect of ethanol, aspirin, and caffeine on daphnia’s heart rate. Not only do these chemicals affect heart rate, but they also affect the frequency of reproduction, number of eggs produced, and body structure. Pesticides similar to these chemicals can be released into the environment and daphnia re useful in monitoring toxicity levels. The agents being tested in this experiment can be administered to determine the effects of hormones, stimulants, antidepressants, and neurotransmitters.

The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants.

1892: The Boll Weevil entered America traveling from Texas Atlantic Coast, destroying cotton plantations in the south, The boll weevil, is a beetle that consumes buds and young bolls of cotton plants. In 1892, it came to Texas from Mexico

In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung.

A Demonstration of Chemotaxis Between Flies and Various Substances (Sugar vs Bacteria) Abstract: The purpose of this lab based on the Drosophila melanogaster (the common fruit fly) reactions. Since the fly has been studied and observed for many years, and known for its unique chemotactic attractions to different stimuli, it was an ideal organism for the study being conducted. In the experiment the purpose was to be able to figure out whether the flies would be more attracted to sugar or bacteria.

When Jeannette was visiting her friend’s home in Battle Mountain, her friend “pointed toward a shiny gold contraption dangling from the ceiling, which she proudly identified as a Shell No-Pest Strip… I went home and told Mom we needed to get a No-Pest Strip like Carla’s family, but she refused. ‘If it kills the flies,’ she said ‘it can’t be very good for us”’ (64-65). Jeanette’s mother doesn’t want to buy the no pest strip because she wants to preserve nature which seems fine because the lizards will eat the flies, but by doing this she has caused her home to be infested with flies and lizards and decline the family’s living conditions severely. While the Walls home in Phoenix was infested with cockroaches and termites, Jeanette “suggested we buy roach spray, like all our neighbors did, but Mom was opposed to chemical warfare…

In this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05).

Exploratory behaviour can be defined as “activity in an unfamiliar environment” (Sih et al., 2004) Such behaviour occurs either when entering a new environment or being introduced to a novel object. This behaviour stops once the animal becomes familiar with its environment ( Shillito, 1963). Exploratory behaviour has an effect on fitness. Male zebra finches that exhibit more exploratory behaviour, have more breeding attempts and nestlings.

With behavioral psychology, the environment would be the determinant of the observable behavior. In the case with the chicken, the environment would be the road, what is on it, what is on the other side of the road, and anything else within sight of the area. The observable behavior would be the chicken crossing the road. There could be many reasons why the chicken would be crossing the road, such

1.INTRODUCTION OF COMPANY My PESTEL analysis for this piece of writing is based on the famous international lingerie company, Victoria Secret. Victoria Secret was founded in 1977 by Roy Raymond, and his wife. Roy Raymond’s interest in a lingerie line was sparked by his embarrassment when purchasing lingerie for his wife. It was then that he studied the market before deciding to go into business, opening their very first store in Palo Alto, California. His vision then, was to have a store that would make everyone, especially men, comfortable shopping for lingerie.

Best Propane Mosquito & Insect Fogger When it comes to eliminating mosquitos and other flying, biting insects, you may feel that there is no hope. These insects seem to be everywhere and they are worse when you want to be outside. There are traps that you can use to catch them, pellets that can repel them, sprays that you can put on yourself, and more, but they will still find a way to get to you when you walk outside to enjoy the summer days. That is why many say that a fogger is the best possible way to eliminate the bites, but is it practical for you? We are here to answer that question by talking to you about the best propane mosquito and insect fogger available.

In the journal Judgement and Decision Making; Paul Rozin along with his colleagues (Carol Nemeroff, and Paul Slovic) implemented a series of studies covering about two thousand American adults and college students. In one study, it was discovered that people were disinclined to consume a favourite beverage when a completely sterilized cockroach was dipped into it. Rationally, they were aware of the fact that the drink was safe; however, couldn’t seem to cross over the hurdle of a cockroach being dipped in their drink. In another experiment, students were provided with chocolate that had been sculpted to look like poop. Again, realistically, they were aware of the fact that it would still taste like regular chocolate.
