Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Acetic Acid H 3
842 wordsIn the simple formalism proposed independently by Bronsted and Lowry in 1923, an acid was defined as a proton donor and a base was defined as a proton acceptor. In the simple acid-base reaction shown below, H 3 O+ is termed a Bronsted Acid, and HO- a Bronsted Base. In writing organic reaction mechanisms, the flow of electrons is often shown using "curved arrows" and in the example shown, the arrows are designed to show that an unshared pair of electrons from hydroxide anion moves to abstract a p...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

Loss Of Appetite Biological Warfare
1,326 wordsAnthrax (Bacillus anthracis) is an acute infectious disease caused by the spore-forming bacterium. The most common victims of anthrax are warm-blooded animals, but it can also infect humans. Anthrax spores can be produced in a powdery form for biological warfare. When inhaled by humans, these particles cause respiratory failure and death within a week. Because anthrax is considered to be a potential agent for use in biological warfare, the Department of Defense (DOD), in 1998, announced it would...

Nuclear Reactions Light Years
873 wordsMagnitudes The magnitude scale Stars Stars Magnitudes The magnitude scale was invented by an ancient Greek astronomer named Hipparchus in about 150 BC He ranked the stars he could see in terms of their brightness, with 1 representing the brightest down to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus 1 st magnitude stars and ones much, much fainter than 6. As it turns out, the eye senses brightness logarithmically, so each increase in 5 ...

York W W Norton Neutral Stimulus
1,968 wordsHow has preparedness theory attempted to integrate a Pavlovian model of the acquisition of specific phobias with this biological specificity? What is the status of Preparedness theory today? When confronted with a phobic object or situation an individual appears to have little control and no alternative but to avoid the feared object or situation (Ohman &# 038; Soares, 1993). Consequently, individuals with a phobia can be vulnerable to anxiety induced automatic reactions to an object or situatio...
