The Red Queen Hypothesis The Red Queen Hypothesis was formulated by Van Valen in 1973‚ and its original purpose was to give an understanding of the adaptation dynamics between species (Vermeij and Roopnarine‚ 2013). The principles of The Red Queen Hypothesis is clearly formulated in McCune (1982)‚ that states ”all taxa are running on a treadmill powered by an environment which deteriorates at a stochastically constant rate. The result is that an ancient taxon is no better adapted than a younger

the null hypothesis and accept the alternative because some of the plants in the pot with the larger amount of seeds did not even start to grow. All of the plants in the groups with 5 seeds at least grew. This indicates that dependent variables such as competition and the environment itself has an influence on how a plant grows and develops. If the T-Stat>T-Critical‚ then we reject the null hypothesis and choose the alternative. The only one we actually accept the null hypothesis are the Leaves

Compare the Social Brain Hypothesis and the Visual Specialisation Hypothesis The aim of this essay is to investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group

The Sapir-Whorf hypothesis is the idea that the difference in language limits and affects our thought process to only the language one speaks‚ therefore‚ not depicting the world and culture in ways others that different languages may perceive it. Sapir created this hypothesis while his student‚ Whorf‚ was the one who popularized it. This theory depicts the idea that language constricts one to only their way of life and would not be able see things in the same aspect that someone of a different language

The hypothesis for the Oil Absorbency Lab was rejected. My hypothesis was that if a person puts a sponge in materials “crude oil”‚ then it will absorb the most amount of oil. The data collected from this experiment rejected the hypothesis because it stated that the sponge would absorb the most oil‚ but the sponge did not absorb more oil than the rag. The rag and sponge’s ranges were for the first trial was 53.0g‚ the second trial was 51.0g‚ and the third trial was 46.0g and the rag. The rag and

The alternative hypotheses in this case is dropping an atomic bomb against your enemies will end war and save lives. The null hypothesis was ending war and saving lives had nothing to do with the reason why the atomic bomb was dropped. It was dropped on the sole propose of showing the world that it would be willing to use nuclear weapons against its enemies. Finding the data on how many times we used bombs on enemies and non-enemies can test both hypotheses. After that we will take a look at the

review only skims the surface. There a many factors to consider when trying to understand the link between foster care placements and academic success. Factors such as resilience‚ family support‚ mental stability and‚ financial stability require in depth examination. Therefore‚ in order to better perspective on the issues‚ systematic research is needed. A potential study which may begin to examine some of the critical factors would focus on what factors might contribute to academic success in foster

Purpose and Hypothesis: Purpose To determine if light intensity affects the rate of growth in Brassica rapa. Hypothesis If the plant that is exposed to high intensity light grows more‚ then plants can adapt to absorb more photons for photosynthesis. Eventually‚ the rate of photosynthesis will top out‚ and stop increasing‚ due to the lack of one of the components necessary for photosynthesis. Background: Photosynthesis is a process used primarily by plants but sometimes by other organisms to

This paper attempts to list theories and hypothesis testing the theories of suspecting factors leading to the cause of teen suicide. Statistics and research methods applied indicate that the mortality rate is different among states. One theory is true‚ that teen suicide is on the rise. Theory in research is an

Abstract The purpose of this research paper is to prove or disprove the hypothesis of the less gun control we have will result in a decrease in murder rates. After analyzing the findings‚ the majority of the articles advocated that the correlation between gun control and murder rates is that the less gun control equals less murder rates. This is due to the fact that countries in the past have tried banning handguns but ended up with higher murder rates. An even more gun control ended up increasing
