Population growth in yeast Aim: To study the population growth rate of yeast‚ a microorganism Saccharomyces cerevesiae Variables: | | Units | Independent variable | Time the readings were taken | Hours | Dependent variable | Absorbance (increasing yeast population) | - | Controlled variables | Units | Possible effects on result | The wave lengths | Nanometer | since the transmission and absorbance is being measured at a specific wave length‚ so if we change it the results

Title: Inhibition of Yeast Glycolysis Abstract: The purpose of this experiment was to study carbon dioxide emissions from yeast‚ as well as their respiratory rate and to use that data to study how glycolysis inhibitors affect the respiratory rate. In our experiment‚ we tested how 8.75% glucose + 1.25% NaCl‚ 8.75% glucose + 1.25% glucose-6-phosphate‚ 8.75% glucose + 1.25% citric acid‚ and yeast solution‚ all mixed with distilled water‚ affect carbon dioxide volumes and respiratory rate. Our results

Alexander Charles‚ what a nice name. I wonder if Mr.Charles was an English teacher? In his poem star-crossed‚ Charles talks about two skeletons discovered in Mantua Italy. These skeletons "linked in a lovers embrace" are the underlying theme throughout the poem. At the the beginning of the poem Charles links love to these 5000 year old lovers while at the end he links them to his age. However he incorporates a sense of bias in the poem. "I shall grow old" age is a something that some

Candidiasis Commonly known as the Yeast Infection Candidiasis is an infection caused by Candida fungi‚ especially Candida Albicans. These fungi are found almost everywhere in the environment. Some may live harmlessly along with the abundant "native" species of bacteria that normally grow the mouth‚ gastrointestinal tract and vagina. Usually‚ Candida is kept under control by the native bacteria and by the body’s immune defenses. If the native bacteria are decreased by antibiotics or if the person’s

Mock Newspaper After the Cross Government allowed a small number of Nought children to attend Cross Private Schools throughout the country as a apart of the “Nought Benefit Package”‚ protests were staged across all schools that had accepted the Noughts to become a part of the daily education program of a typical teenage Cross. Many Cross students throughout the country expressed their negative views on the Noughts joining in their learning community by surrounding the front gates of their schools

Title : Measuring the rate of oxygen uptake. Objectives : 1. To demonstrate the uptake of oxygen in respiration. 2. To measure the rate at which an organism respires. 3. To learn how to set up the apparatus for respirometers. Introduction : Respirometer A respirometer is a device that been used to measure the rate of respiration of a living organism. This can be measured by calculating the rate of exchange of oxygen and carbon dioxide. A simple respirometer designed to measure oxygen

Dear Mr. Davies‚ I was wondering if we can have strawberries at the salad bar. Could we also have strawberry smoothie for children under year 7-8. About the strawberries. If you had not much time left to cut them‚ it does not matter because you can just rinse them under the water and put them in a bowl ready for lunch. Sometimes when I would like a jacket potato the sign on the board will say `JACKET POTATO AVAILIBLE EVERY DAY` but when I come up to the dinner ladies they say there is no more

Noughts and Crosses by Malorie Blackman Noughts and Crosses is an amazing novel written by Malorie Blackman‚ about a world that is divided in two‚ the dark skinned crosses and the light skinned noughts. Crosses are the most privileged race and are the rulers‚ noughts are slaves to the crosses and are second class citizens that are treated very poorly‚ quite a lot like what’s happening in our world today but if the race and class were switched. Sephy is one of the main characters‚ she is a cross

Aerobic respiration in yeast Research question: What was the effect of anaerobic respiration in different environments determined the increase in size of a dough by the temperature? Hypothesis: It is hypothesized that if the temperature increases the dough will become bigger and bigger. Independent variable: (change) • Temperature • Height of the dough Dependent variable: (doesn’t change) • Amount of vegetable oil • Time • Volume of yeast solution Control variables: Variable
