if UV Radiation induced a mutation in the DNA of Serratia Marcescens and prevented the production of the red pigment called Prodigiosin. Hypothesis: Maybe the disappearance of red color in Serratia Marcescens is caused by the UV light which induces mutations in its DNA and is known as a common mutagen. Prediction: If UV light mutates the DNA of Serratia Marcescens then the red pigment colonies of the bacteria will no longer be produced. Independent Variable: Ultra Violet Radiation Dependent

Corn‚ beyond doubt‚ is one of the biggest stories in human history. The “ruler” of the entire American food chain is corn. From farmyards to supermarkets‚ countless types of food ingredients and even forage are corn-derived. In 2007‚ the States alone produced 13 billion bushels of corn. Such massive reap is attributed to corn-farm subsidies by the government‚ a “legacy” of the Great Depression which gives corn an unnatural edge over other kinds of crops. The policy is‚ in fact‚ skewed in favor of

The Documentary ‘King Corn’ is an intersting and entertaining account that examines the impact of the corn industry on food production in America. The film follows Curtis Ellis and Ian Cheney‚ two recent university graduates who set out to study the overwhelming influence that industrial corn has on the varieties of foods that America consumes each year. The concept of the film is introduced when Curt and Ian have samples of their hair examined‚ and are surprised to find out that the large amounts

Uses of Radiation in the Medical Industry Although scientists have only known about radiation since the 1890s‚ they have developed a wide variety of uses for this natural force. Today‚ to benefit humankind‚ radiation is used in medicine‚ academics‚ and industry‚ as well as for generating electricity. In addition‚ radiation has uses in such areas as agriculture‚ space exploration‚ law enforcement‚ geology and many others. However‚ in the medical industry‚ radiation is used for x-rays‚ therapeutic

The Good‚ the Bad and High Fructose Corn Syrup Considered natural‚ corn syrup in essence is a sugar; it is a sugar made from corn. I would reckon that most folks think that high fructose corn syrup (HFCS) is just another additive of food ingredients and never give it a second notion. I was once like that as well; it was not until about two years ago I realized that corn syrup was somewhat controversial. Now‚ after reading Michael Pollan’s The Omnivore’s Dilemma‚ I realize just how controversial

Convection‚ and Radiation The three types of heat transfers are Conduction‚ Convection‚ and Radiation. Heat always moves from a warmer place to a cooler place. For example hot objects that are in a room that is cooler than the temperature of the object will eventually cool to room temperature. First is conduction‚ conduction is heat transferring through direct contact of substances. Then convection‚ which is the transfer of heat by the movement of the warmed matter. Lastly radiation is electromagnetic

5 When Radiation Therapy Kills 1. What concept in this chapter are illustrated in this case? What ethical issues are raised by radiation technology? There are three basic concept that can be apply in ethics in an information society. The concept that illustrated in this case is accountability. Accountability can be define as the responsibility to someone or for some activity. In this case hospital need to find the mechanism to identify the responsible parties for the radiation therapy

down starch/amylose in plants. Corn kernel contains starch‚ sugars and cellulose. This experiment focused on the effect of amylase on corn extract in respect to the rate of fermentation. Since amylase breaks down starch‚ the part of corn that contains the most starch should have the fastest rate of fermentation and the greatest amount of CO2 produced. Strength In our positive control group‚ the rate of fermentation is the highest (Figure 2)‚ and the sample solution (corn syrup‚ yeast‚ and calcium chloride)
