disaster. The plant life was sick‚ the snails were dying‚ and our fish died. As the project continued‚ it became healthier once we changed out the water. The first week the plant started flourishing‚ the snails and fish started to survive. In the decomposition chamber‚ it housed the entire time we started with leaves and some fruit which decomposed into the soil. When the project was over‚ it was nearly all decomposed. In the terrestrial chamber‚ the flora flourished the entire time. Our plants were

are also special because very little of the actual enzyme is actually used up in the reaction. In this lab two different factors‚ temperature and pH‚ were tested to see what type of effect they would have on catalase‚ a potato enzyme that synthesizes H2O2. The data my group collected supported one hypothesis‚ that an acidic environment would not be conductive to enzyme behavior‚ and disproved another‚ that higher temperatures would yield greater enzyme byproduct production.

where the demand patterns of individual product groups are highly seasonal. Three forecasting models‚ namely‚ Winter’s‚ decomposition‚ and Auto-Regressive Integrated Moving Average (ARIMA)‚ are applied to forecast the product demands. The results are compared with those obtained by subjective and intuitive judgements (which is the current practice). It is found that the decomposition and ARIMA models provide lower forecast errors in all product groups. As a result‚ the safety stock calculated based

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in
