Ms. Lunsford Honors Chemistry 12/6/2011 Abstract Yeast is widely used for making bread‚ beer‚ and wine. People all over the world drink and eat those products. This projects looks at which fruit juice with a higher percentage of sugar will produce more fermentation. The original purpose of this experiment was to determine the amount of fermentation of 3 different fruit juices after adding a certain amount of yeast. By measuring the type of fruit juice (independent variable) the amount

There are more than one forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide

Cervisiae<br><br><b>Description</b> - Yeast is a unicellular organism that lacks chloroplasts. They are so small that it can ’t be seen by the naked eye and they are so small that it would take 4000 of them lined up side by side to measure an inch. <br><br><b>Habitat</b> - Yeast lives on and is nourished by dead or living plant or animal matter. The ideal conditions of yeast is high humidity and temperature‚ plus lots of food. In bad conditions though the yeast produces a second cell wall for protection and the yeast contents

Everyone has yeast in the body‚ but it is required in minimal quantities. However due to various reasons like lifestyle change‚ medications‚ foods we eat‚ and type of clothing that we use‚ you find many people struggling with yeast infections. It is also referred to as Candida. Women are the most hit though a few men too finds themselves in this mess. But have you realized that apart from the doctor’s medications there are natural ways one can end this menace? Try this homemade easy‚ and natural

To deduce 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

Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride

selfish genetic element: the 2-μm plasmid of Saccharomyces cerevisiae. J Evol Biol 25(11): 2348-56. What are the actors (e.g.‚ what parts of the organism are in conflict) and what are they in conflict over? The 2 μm plasmid of Saccharomyces yeast is in conflict with the cell host‚ this plasmid cost the host through using the cells’ resources ; meaning a burden on the host to synthesize more proteins as well as increasing the amount of DNA the host cells needs to accommodate.
