and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and added to each the corresponding 1 mL of water from tubes A-D. As

Problem Set – Monohybrid and Dihybrid Cross 1. Classical albinism results from a recessive allele. What is the expected offspring from a normally pigmented male with an albino father and an albino wife? 2. A pea plant with red flowers is test crossed and one half of the resulting progeny have red flowers‚ while the other half has white flowers. What is the genotype of the test crossed parent? 3. If we cross two pea plants each heterozygous for yellow seed color genes‚ what would be the

Making Bread with Yeast By Rebecca Coles Introduction Bread is such a common food‚ who would expect it to be made in such a fascinating and clever way? A simple loaf contains just four main ingredients; flour (the main ingredient)‚ warm water (the yeast prefer the water warm)‚ salt and of course the yeast‚ tiny microscopic fungi that help the bread rise. Although fascinating the process is surprisingly simple; first‚ the flour‚ sugar and water is mixed together with yeast to make the bread

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
