-------------------------------- 1 A scientific paper submitted in partial fulfillment of the requirements in HNF 12 laboratory‚ 2nd sem.‚ 2012-2013. OBJECTIVES 1. To enumerate the principle and methods in fermentation; and 2. to identify the factors that affect the efficiency of fermentation. INTRODUCTION Vinegar has been traditionally used as a food preservative. Vinegar retards microbial growth and contributes sensory properties to a number of foods. The wide diversity of products containing

#9- Yeast Fermentation Dates of performed work: 3/26/18 Date submitted: 4/23/18 Abstract Yeast are unicellular fungi which act as facultative anaerobes. This means that yeast is able to produce ATP by aerobic respiration while oxygen is present‚ but are also capable of anaerobic respiration if oxygen is not available. This is called fermentation. Fermentation allows glycolysis to continue in the absence of oxygen. The type

Discuss the role of negative feedback in living organisms and how it benefits these living organisms? (25 marks) Negative feedback is the process by which changes occur to bring an organism’s internal environment back to the normal level. One example of negative feedback in a living organism is the ways humans regulate their blood glucose levels. I will firstly discuss the processes that occur as a result of blood glucose levels being too low. When blood glucose levels are too low the pancreas

The claim that globalization generates poverty has been the focus of many debates for the last twenty years‚ including the debate between Carlos Caretto‚ Gillian Crowl‚ Steve Grossman‚ and Annie Wong on February 21‚ 2005. Caretto and Crowl argued that poverty is an indirect result of globalization as is evident by high unemployment rates‚ wage inequality‚ and diminishing health and educational programs. Grossman and Wong contended that globalization does not generate poverty‚ but it in fact helps

One major ways for the survival of all organisms is called adaptation. When it comes to Intertidal Organisms their no different. Intertidal Organisms inhabit the specific area between low tide and high tide next to the rocks on the coasts‚ marshes and or wetlands. Theses organisms can be from sea stars to types of algae and many more. As the tides come in‚ the habitat of intertidal organisms are sprayed with salt water. Then after the tide depletes‚ the habitat is exposed to the sun. It makes

and harboring wildlife. Climate control is obtained by moderating the effects of sun‚ wind‚ and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter‚ we value the sun’s radiant energy. Therefore‚ we should plant only small or deciduous trees on the south side of homes. Wind speed and direction

Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit

Introduction: An oxygen sensor‚ or lambda sensor‚ is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under supervision by Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The most common application is to measure the

The Absence of Passion In Aldous Huxley’s Brave New World‚ the government is a controlling figure that sets varying limits over all of it’s citizens. They have sculpted a perfect world‚ but with perfection comes sacrifice. They have removed all ideas that could possibly lead to social instability. To our society not having family‚ daily drug holidays‚ and lack of knowledge are outrageous ideas‚ but the people of the World State know of nothing else. The people of this new society not only have
