Biology 301 12/3/2012 The Effects of Relative Fitness of Drosophila Melanogaster on Evolution Abstract This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments‚ one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism

In this population cage‚ it used Drosophila melanogaster because is a common model organism for genetic studies. In this population cage‚ it was calculated the coefficient of selection of an actual sample and an ago sample. In this experiment‚ it was used the actual sample #4 and the ago sample #3. The result of the coefficient of selection should be at the rate between 0 and 1. The result was 0.82‚ so it was a good result of the coefficient of selection between these two samples (#4 and #3).

An Eye For An Eye Capital punishment has often been referred to as ‘an eye for an eye’. This idiomatic expression dates back to Mesopotamian times from Hammurabi’s Code. The phrase represents what many view as a harsh sense of justice based on a need for reprisal. What is the real purpose for capital punishment? Many Americans are becoming less and less concerned with using punishment as a deterrent for future crimes and more focused on using it as a means of retribution. In a recent study‚ eighty-eight

An Eye for an Eye Life is a precious gift from God. Even when a person has no material possessions‚ life is still possessed. In light of these observations‚ it is logical to assume that murder‚ the taking of another’s life‚ is the most heinous of crimes. Undeniably‚ penalties imposed upon criminals should match the crimes committed. Therefore‚ the worst crime possible‚ murder‚ should receive the worst penalty possible‚ death. One argument against the death penalty comes from the Bible‚

Taste discrimination in young and old Drosophila melanogaster Introduction The ability to discriminate taste is critical for the survival and nutrition of an organism (Sellier et al.‚ 2010‚ Gordesky-Gold et al.‚ 2008). Many animals rely on their taste organs to detect and discriminate various types of taste such as sweet or bitter (Weiss et al.‚ 2011). When these organs come in contact with a food source‚ signals are sent to taste receptor cells. The activation of certain taste receptor cells by

urgency and desperation due to the constant interruptions and the use of dramatic irony. Juliet’s promise to Romeo to "follow thee my lord throughout the world" is full of dramatic irony and foreshadows the final scene of the play‚ when their star crossed love forces them to kill themselves. The simple phrase “my lord” would then have been viewed as blasphemous and a very disrespectful thing to say. This therefore exaggerates the passion in Romeo and Juliet’s love as well as their willingness to risk

Effects of Organic Food on Drosophila Melanogaster A new study has shown that fruit flies that lived on organic foods tended to be healthier than those that lived on conventional foods. The two things that researchers based their conclusions for health on were fertility and longevity. These two things are two important aspects to a fly’s life. On both of these tests‚ the flies that were fed organic food performed better than the flies that were fed conventional food. They survived for a longer
