for starch and a negative Benedict test for its reduced sugars. What is cellulose? According to your results‚ does salivary amylase digest cellulose? Cellulose is a polysaccharide found in plants to provide rigidity to their cell walls and salivary amylase is not able to digest it because there were no positive signs of the Benedict test which should have been positive if a breakdown did occur. What happened to the cellulose in tube #6? It was digested by the bacteria showing a very positive sign

Reticulum - Once rumen is full goat regurgitates‚ the reticulum allows for this to happen. Omasum – bacteria and micro-organisms breakdown food. Obomasum – secretes acid and enzymes to break down proteins and fats. Stomach contains hydrochloric

Nitrocellulose Materials Christian Friedrich Schönbein’s procedure has been widely used. It calls for 1 part cotton to 15 parts acid. concentrated nitric acid concentrated sulfuric acid cotton balls (almost pure cellulose) Nitrocellulose Preparation Chill the acids below 0°C. In a fume hood‚ mix equal parts nitric and sulfuric acid in a beaker. Drop cotton balls into the acid. You can tamp them down using a glass stirring rod. Don’t use metal. Allow the nitration reaction to proceed for about 15

Attempt to produce man-made fibre was first started with Artificial Silk’ at 1855 in England by Swiss chemist named Audemars. The fibrous inner bark of mulberry tree was then chemically modified to produce cellulose. At 1880s‚ sir Joseph Swan an English chemist experimented by forcing the cellulose liquid through fine holes into a coagulating bath. First commercial production of artificial fibre was achieved by French chemist Count Hilaire de chardonnet at 1889 in France. At that time he produced

chemical equation; discuss the chemical reactions taking place‚ and the law of conservation of mass in your answer. The wood from the tree has undergone a chemical change. When you burn wood‚ you are converting the wood into hot gasses. When burning Cellulose molecules of C6H10O5‚ this produces a lot of H2O and CO2. There are large volumes of gasses that are produced during the burning process. The wood is broken down and reformed into other molecules or dissipated as heat and light energy. The wood

Paper towels represent an everyday necessity for humans and each brand has different properties. With New Milford High School using a different type of paper towel than ones most homes have‚ it is uncertain if there is a drastic difference between the two. In attempt to figure out the difference between the brand Kirkland and Tork‚ in terms of paper towels‚ an experiment was conducted. By creating an experiment designed to test the absorption of different paper towels‚ the results can possibly help

tubiform and a sacciform fore stomach) containing lots of microbes. The stomach is bigger than that of a hindgut fermenter considering its usually a bigger animal‚ the stomach has an extra chamber to help devour glucose from the cellulose (the herbivores diet is largely cellulose and is broken down by the microbes) and nutrients and then produce fatty acids that the animal can use for energy‚ It also usually has a long small intestine (and usually has small expansions along the intestines to accomodate

provide the best hope of implementing the flexible batteries which can shrink our gadgets even more. A paper battery is a flexible‚ ultra-thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and supercapacitor‚ combining two components that are separate in traditional electronics. This combination allows the battery to provide both long-term‚ steady power production

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental

There are many different types of relationships and interactions between organisms A wide array of interactions among plants‚ animals‚ and microorganisms occurs in nature. Some of these relationships are characterized by a close physical association among species that continues for a large period of the life cycle. In 1879 German botanist Heinrich Anton de Bary coined the term "symbiosis" to describe these relationships‚ meaning the living together of different species of organisms. Many people associate
