FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

purpose‚ according to Zimbardo‚ was to see if people’s behaviors are affected by their social situations or by their morals and personalities. Zimbardo’s hypothesis was that prison guards would be brutal due to their mentality of being prison guards. The prisoners likewise would be rebellious due to the fact that prisoners are people who broke the laws in the first place. There are several weaknesses in the way that Zimbardo designed his study experiment. One was that his sample didn’t successfully

fuels and reduced chemicals. Here we report the quantitative analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis. The kinetics of glycerol fermentation in a batch culture was simulated using a dynamic model consisting of mass balances for glycerol‚ ethanol‚ biomass

Overall Cost Leadership Porter defines “Overall Cost Leadership” as the strategy in which a company differentiates from others by having the lowest prices of the market. One example of this strategy correctly performed in Australia is Woolworths. According to Jhon Steen (2009)‚ in order to accomplish such prices‚ Woolworths focus on two main points: Logistics and Economics on Scale. They have learned to manage the supply chain in a very efficient way‚ investing in technology and reducing the

Cause and effect Essay | Definition: In this kind of essay‚ the aim is to explain the causes (reasons) or the effects (results) of an event or situation. Example: Causes of air pollution (multiple factors leading to air pollution). Example: Effects of watching too much TV (many effects of a situation). Sometimes an event causes something to happen‚ and that situation leads to another event‚ and it causes another event to happen. This is called the causal chain or

w The Effect of Changing the surface area on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area

The question being answered was what kind of effect the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it
