good-genes and sexy-sons hypotheses focus on direct benefits associated with female choice. The good-genes hypothesis proposes that a female will choose to mate with males that they believe will produce better offspring. Typically this decision is based off a phenotypic trait that is an sign of higher genetic fitness‚ however sometimes these traits are not good indicators. The sexy-sons hypothesis is similar however it posits that females will choose the most attractive males to mate with so that those

Hypothesis Testing The sole purpose of hypothesis testing is to determine whether or not research that has been collected is proved or disproved; usually allowing up to a 5% error factor. By using this 5% margin of error a researcher can consider the question of research being conducted is proven. There are five steps to be followed in doing hypotheses testing. The steps are: developing the research question‚ specifying between null and alternative hypotheses‚ calculating the statistic‚ computing

Bacteria are the most ancient life forms‚ most bacteria are so small that under a light microscope you can only see them as little dots. Some groups however grow to larger sizes and have spectacular shapes (1). Bacteria are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and the live bodies of plants and animals (2). Bacteria is mostly thought of as a pathogen‚ while it is true that

The Abyss - Unknown Death. It is an odd thing‚ one moment you’re sitting in front of a desk pondering how to answer the question in front of you‚ the next extreme pain as if you’re entire body is being roasted alive. Then‚ well nothing. Just darkness‚ dull and boring. Those were the thoughts of the boy as he drifted in the abyss. His mortal coil no longer existence‚ only a dimly lit sphere in its place. “I’m not sure what’s worse‚ exams or this...” he muttered inwardly‚ originally he hadn’t been

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar

1. The Schumpeter hypothesis links firms operating under a monopoly market structure as most important for technological innovation. Arrow‚ on the other hand‚ suggests most progress can be achieved in a perfectly competitive market. Compare and contrast these two arguments. An important issue in economics is how market structure affects innovation. In 1934‚ Schumpeter observed that some markets become increasingly concentrated‚ both with respect to innovation activities and market competition

is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature‚ pH level‚ and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria can also be used in many other

The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too‚ for example bacteria‚ such as Rhizobium‚ are in symbiotic relationship with the root system of some terrestrial plants. The most important elements‚ which allow terrestrial plants grow well‚ are
