Regarding temperature changes, the null hypothesis is that their heart rate will remain constant regardless of increasing or decreasing the external temperature of the Daphnia. The alternative hypothesis is that the heart rate will increase with more heat and will decrease with a decrease a decrease in temperature, meaning that heart rate and temperature are directly related. In regards to the chemicals acetylcholine and epinephrine, the null hypothesis is that both chemicals will have no effect
the group with the “popular” music will yield the highest reaction times whereas the classical music group and the no music group will yield similar reaction times. The third hypothesis also includes participants who multitask will complete fewer task compared to the participants who perform single task. The last hypothesis state that the popular music will complete the least amount of tasks in comparison to classical music and the control group, the group without music. This study included 60 college
“Plant communication affects plant communication and defense” published in the Proceedings of the Royal Society B. A team forms the hypothesis plants that are more closely related are able to communicate more effectively, thus allowing them to establish better defenses against predators, than plants not as closely related. With a thorough analysis of the teams hypothesis, methods, results, and conclusion, their findings can be summed up as “a step in the right direction”, but by no means provides impermeable
The Goal My goal is to find the probability of wining in tic-tac-toe game given that you make the first move. To obtain hypothesis bases on my goal I have to state some conditions and facts on the game. They are: 1) There are 362, 880 ways of placing O’s and X’s. 2) When X make first move, possibility of X winning is 131,184, O winning is 77, 904, and 46, 080 tied games (Source: http://en.wikipedia.org/wiki/Tic-tac-toe). After eliminating rotations and/or reflections of other outcomes, there are
Discussion Based on the existing literature on the subject, two hypotheses were proposed. The main hypothesis was that participants in the no phone group would talk more than participants in the with phone group. The secondary hypothesis was that female participants would talk more than male participants regardless of what group they were a part of. Both of these hypotheses were supported by the findings of our study. There was a statistically significant difference in how much participants talked
Yikes! Although these studies concentrate on hand washing, they are not helping to support our hypothesis. We test the hypothesis that men are more likely than women to throw away their trash in a busy food court. Method Participants were random men and women (M = 20, F = 21) who visited the food court once during the week and once during a weekend day at the Galleria Mall located in Rocklin, California. The participants did not know they were part of a correlation or observation test. The dependent
What if California’s drought continued? Not only the people in California would care, but as a whole, the United States would; California is one of the main source where food grows. I predict that all the animals from fishes to bears would have to migrate to find a new home because of lack of food and fresh water in the area. As the scientists find a solution to the problem, Californians would try their best to continue to spare the water. Furthermore, water would become more expensive. Due to high

regenerate better than the smaller sections. Our results showed the null hypothesis was supported because the short anterior segments grew the most. The reason for this occurrence may be the worms’ survival, regardless of segment length, is unpredictable. This would also offer an explanation as to why our control worms died in the end of the experiment. Introduction Lumbriculus variegatus, also known as blackworms or California blackworms, are known for their abilities to regenerate. Lumbriculus variegatus
The Effects of “Evoking Freedom” Technique on Compliance Social influence and the power of social situations have always been central topics of inquiry for psychologists due to their impact on our everyday lives. Social influence refers to the ways in which people alter their attitudes, emotions, and behaviors of others. Every day, we encounter countless attempts by other people to influence us. Likewise, we try to influence others. Compliance is a kind of social influence in which an individual
