...Fruit flys are used as an experimental model because they produce a large amount of offspring in a short amount amount of time(2 weeks). Having a large sample size makes your results more accurate and reliable. I wish to study the black body and wild type traits of the body color characteristic. The phenotype of the black body fly would be having a black body color. The phenotype of a wild type fly would be having a orange body color. During this lab, my goal is to discover which of the two traits is dominant to the other. My hypothesis is as follows: If the wild type trait is dominant, then a cross between a wild type phenotype parent and a black type phenotype parent will result in an F1 distribution of either 100 percent wild type phenotype...

...Introduction: The experiments of Beadle and Tatum proposed a hypothesis that stated that certain gene traits are related to particular enzymes that are missing. Investigation #19 allowed students to investigate and identify the chemical differences within species of fruit flies, in order, to understand the actions of their genes. The following materials were used to visually see the chemical differences in Drosophila melanogaster mutants: the eyes from the flies, paper chromatography, a good solvent for the paper chromatography to interact with and a UV light source. The seven species of flies used include: wild type, white, cinnabar, brown, cinnabar brown double mutant, sepia and white apricot. The phenotypes of these species varied from a red pigment, brown pigment and a white pigment. When a red pigment and brown pigment are crossed, the resulting color is brick red....

...Wild Fruit Flies Bred With Scarlet Fruit Flies Introduction: Drosophila melanogaster is the scientific name for fruit flies. The flies are widely used today for genetics, physiology, and life history evolution. Since it is easy to care for, has 4 pairs of chromosomes, breeds quickly, and lays many eggs, the fruity fly is used for numerous studies. In this lab, fruit flies are to be examined to study heredity. With each new generation, probability, protein synthesis, and the principles of DNA, are all able to be seen within this experiment. For this lab, wild fruit flies will be bred with scarlet fruit flies. The trait to be examined in this lab is the eye color. Wild fruit fly's’ eye color (red) is a dominant trait. The scarlet fruit flies have scarlet eyes, and it is a recessive trait. Fruit flies are very small, but their eyes are complex. They have compound eyes. One eye contains hundreds of light-sensing units called ommatidia. Each ommatidia has a lens and a set of light-receptor...

...F2 generation of red eyes fruit flies crossed with white eyed fruit flies? BACKGROUND INFORMATION: sexually dimorphic . Law of independent assortment Drosophila Melanogaster, the fruit fly completes its life cycle in 10-12 days, makes a large number of offspring, and it has many types of hereditary variations that can be seen with low power microscopes. Drosophila has four pairs of chromosomes, a relatively small number which are easily located in the large salivary glands. Many factors combine to affect the length of the Drosophila life cycle. Temperature affects the life cycle the most. At room temperature the average life cycle of the Drosophila is about 12 days. HYPOTHESIS: That in a sex-lined cross between...

...Good Things to Know about Worm Castings This is an overview of benefits known about worm castings. The overview is generated from information disseminated by such major Universities as Ohio State, Cornell University and UC Davis. This information also comes from other institutions and companies such as the California Vermiculture, LLC and the Australia SIRO. Their research goal was to establish the value of worm castings. Their test results have shown improved flower size, bloom quantity, quality, and color. Fruit and vegetable tests results have shown yield improvements from 15% to 57% as well as improvements in taste and appearance. The information you need to know and consider is presented below in a list format, which we believe is easier and quicker to reference and grasp. Some of the discoveries made will surprise you. Most people will be amazed by the following information if they have no prior exposure to the absolute beauty and completeness of the worm casting. Basic points to start: Worm Castings are the worm feces. The castings are made up of live biological organisms. The organisms include fungi, actinomycetes , beneficial bacteria, pseudomonads , plant growth regulators, yeasts, molds, trace elements and the famous N-P-K ratings used by fertilizers, to reference the Nitrogen, Phosphorus and K (which is the chemical symbol for Potassium) quantities promoted by the fertilizer industry (more on this below).

...Eyeless mutation gene located within the second intron of Drosophila melanogaster Justin Lazarus Genetic 300 Abstract The following experiment was conduct over a several week time span to determine and identify the mutation that is causing the eyeless mutation within the Drosophila melanogaster fruit flies. The experiment included genome sequencing and comparison between the Drosophila melanogaster wild type and the Drosophila melanogaster eyeless type. After combining the two different phenotypes. We determined that we were unable to visualize the mutation at a chromosomal level, as both wild-type and eyeless flies looked similar. The experiment involved electrophoresis and Polymerase Chain Reaction (PCR) through which we were able to isolate and amplify the needed DNA eyeless DNA. The difference between the wild-type Drosophila melanogaster and the eyeless Drosophila melanogaster is approximately only 500-nucleotide base pairs. As we see the eyeless phenotype is approximately 3000 base pairs in length while the wild-type phenotype is approximately 2500 nucleotides base pairs in length, a difference of about 500 base pairs. After completing nucleotide sequencing and comparing our data on the blast website, we determined that the eyeless mutation has being interest exons two and three, but more specifically the mutation itself was located within the second intron at base pairs 8264 to 9212.

...Joel Schwartz Final Paper - Draft 7/16/12 Professor Hoge English 1020 Animal Rights Activism: A Domestic Terror Threat Throughout the past two decades, extreme animal rights groups have claimed responsibility for hundreds of crimes and acts of terrorism, including arson, bombings, vandalism, burglary, animal release, and harassment. These crimes have caused damage costing more than one hundred million dollars. While some activists have been captured, animal rights terrorism cells, are extremely difficult to identify and most of the attacks remain unsolved. Although it has been overshadowed by Islamic terrorist threats since September 11, animal rights terrorism still remains one of the United State’s most active terrorist movements. This paper intends to explore the Animal Rights terrorist movement and prove that Animal Rights activists pose a significant domestic terror threat. An increasing number of terrorist activity in the United States has been carried out in the name of animal protection. Although no one has been killed in an attack, the increasingly violent nature of attacks suggests that someone will be proclaimed dead before long. Beginning in the 1970s, hundreds of groups in the United States have advocated for much stricter legal protection for animals. Change has been slow but incremental. Some activists have become frustrated by the pace of legislation, and have become violent. This violence has created an underground terrorist movement...

...Section A: Basic Microbiology 1 SCOPE AND HISTORICAL DEVELOPMENTS IN MICROBIOLOGY “Science contributes to our culture in many ways, as a creative intellectual activity in its own right, as a light which has served to illuminate man’s place in the uni-verse, and as the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large and diverse group of microscopic organisms that exist as single cell or cell clusters (e.g., bacteria, archaea, fungi, algae, protozoa and helminths) and the viruses, which are microscopic but not cellular. While bacteria and archaea are classed as prokaryotes (Gr. pro-before+ karyon-nucleus) the fungi, algae, protozoa and helminths are eukaryotes (Gr. eu-true or good+ karyon-nucleus). Microorganisms are present everywhere on earth, which includes humans, animals, plants and other living creatures, soil,water and atmosphere. Microorganisms are relevant to all of our lives in a multitude of ways. Sometimes, the influence of microorganisms on human life is beneficial, whereas at other times, it is detrimental.
