Duckweed as a nutrient thief and bioremediator Hypothesis: This experiment will evaluate duckweed and its ability to remove nutrients and toxins from water sources. Thus‚ duckweed will kill the organisms that require similar nutrients‚ yet aid the organisms that would otherwise die to toxins. Specifically‚ if one was to place Elodea plants in a tank with duckweed‚ then the Elodea will die due to the lack of nutrients from the duckweed having used the nutrients for its own benefits.

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.

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

absence of one in the prokaryotes; Eukaryotes also have distinct membrane-bound organelles‚ while prokaryotes do not (Stanier et al.‚ 1970a; Mauseth‚ 2009). It is after discovery and examination of these organelles that first led to the Endosymbiont Hypothesis or Endosymbiont Theory‚ as it is sometimes called (both terms are used throughout). In this essay we shall look at the history of the theory‚ how it was formed‚ who the most influential collaborators were‚ and how it is applied to the evolution
