IB Biology Internal Assessment: Yeast Fermentation Rates Planning(a) Question- Growth: What is the effect on Yeast Growth/Expansion during fermentation when mixed in water of varying temperatures? Hypothesis- Temperatures above or below the recommended fermentation temperatures will contain less‚ or be void of growth‚ either due to inactivation or to yeast death. Variables- | | | | |

LACTOSE – C12H22O11 Chemical and Biochemical Properties Lactose is very stable and inert from a chemical point of view. It has no significant tendency to react with the drug or other components of a formulation. Some remarks on the chemical properties of lactose are useful however‚ the low hygroscopicity of crystalline lactose supports its virtual chemical inertness. Most chemical reactions of lactose occur noticeably only in aqueous environment. Because lactose has a very low tendency to attract

and infections to become more virulent. Just how this excess sugar causes damage remains a topic of debate. One plausible mechanism was suggested in Time by Dr. Michael Brownlee of Albert Einstein College of Medicine in New York City (November 26‚ 1990‚ p. 52-59). Glucose is known to be chemically active and can form a temporary bond with many proteins‚ including hemoglobin. Over time‚ some of these proteins become permanently attached to the glucose and these sticky fragments aggregate to form

Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis

Investigating the effects of carbohydrates on blood glucose levels INTRODUCTION There are two types of diabetes which includes diabetes inspidus however the disorder most commonly associated with the generic term ‘diabetes’ is diabetes mellitus. Diabetes mellitus is condition whereby blood sugar levels are far too high due to poor metabolism. There are two variations of the disorder which are Type 1 and Type 2 Diabetes Mellitus. Type 1 diabetes occurs as a result of the body’s inability to produce

exercise on heart rate/ breathing rate? Justification Pulse is an ongoing wave of pressure in the arteries‚ caused by pumping of heart. Pulse can be measured on the wrist‚ neck‚ back of the knee or any other pulse point where arteries run close to the surface of the skin and compress on the bone. Pulse rates vary from person to person. Your pulse is lower when you rest and increases when you exercise. More oxygen rich blood is needed by the body when exercising so knowing how to take your pulse

best type of flour to make bread rise. The experiment will consist of four different types of flour to make the bread rise. Each type of flour will have different amounts of gluten‚ and some will have no gluten in them. The hypothesis is that the flour with the most amount of gluten in it will make bread rise higher‚ and the flour with the least amount of gluten will make bread rise the least. In this case the flour with most amount of gluten in it is whole wheat flour. All purpose flour has

Introduction Plants are considered photoautotrophs which means that they draw energy from the sun and use it to form starch molecules. The process by which this happens is called photosynthesis and results in the formation of oxygen and glucose. Plants take in carbon dioxide‚ water‚ and light then release oxygen back into the air. This process happens because of the movement of hydrogen to the hydrocarbons that are produced during photosynthesis. The discovery of photosynthesis is attributed to

factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory experiment was to determine which solution would have the highest impact on oxygen production within the aquatic plant‚ Elodea densa (Brazilian Waterweed). The
