The definition of weathering is to wear away or change in appearance or texture due to long exposure to air. This concept is also applicable to the human body. This is called the weathering hypothesis. The weathering hypothesis was coined by Dr. Geronimus‚ which states that African Americans in the United States experience early health deterioration‚ measured by biological indicators of repeated exposure to and adaptation to stressors (Geronimus‚ Hicken‚ Pearson‚ Seashols‚ Brown‚ & Cruz‚ 2010).

Hypothesis: The bigger the area‚ the larger species it can support. Aim: To see how the size of an area affects the relationship between species diversity. Diversity is a range of different elements. Habitat size determines diversity relationship(Edition of Nature‚ March 28 2002). In the research of specie diversity ‚ it was found out that more productivity was done when two different types of species were in one area. It was also said that diversity goes down but as it goes down the productivity

We came up with certain hypothesis that are based on our predictions: “Users experience an “illusory correlation” when they are asked to rank the generic brands.” Users tend to think that the generic brand would be less tasty even though in reality that’s often not the case. However because it is a generic brand they have prejudices against it. We expect participants to create an illusory correlation between the brand‚ its quality and the price. In our case

The two visual systems hypothesis talks about the processing of the visual information in two different routes in the brain (van Polanen & Davare‚ 2015). This idea was first introduced in 1982 when Leslie Ungerleider and Mortimer Mishkin described experiments that distinguished two streams that served different functions(Melvyn A. Goodale‚ 1998). They used the method know as ablation or also called lesioning. Using both recordings from neurons and ablation‚ they found that properties of the ventral

The “Descent from Teosinte” hypothesis helps define the difference between maize and teosinte. According to Iltis‚ corn is cultivated teosinte‚ they do not differ in genetic or vegetative features (Goodman‚ 1988). Human select qualities in corn that produce more food‚ larger quantity‚ and efficient yield. Maize and teosinte have the same amount of chromosomes and similar structure due to common descent. At the DNA level‚ teosinte and maize have the same number of chromosomes and almost the same arrangement

The five-step processes for hypothesis testing are the following. Step1. Specify the null hypothesis H0 and alternative hypothesis H1. The null hypothesis is the hypothesis that the researcher formulates and proceeds to test. If the null hypothesis is rejected after the test‚ the hypothesis to be accepted is called the alternative hypothesis. For example if the researcher wants to compare the average value generated by two different procedures the null hypothesis to be tested is [pic] and
