The Spirit Catches You and You Fall Down - Summary and Reading Log Chapter 1 - Birth Chapter 1 goes through the traditional birthing methods and traditions of the Hmong people. One of the most significant traditions is burying the placenta. The placenta has to be strategically buried in a specific spot under the homes dirt floor or when the person dies its soul has to travel back to the placenta. This chapter also introduces the characters Nao Kao and Foua Lee. Nao is husband and father of 13

Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction

Final Paper: “The Spirit Catches You and You Fall Down” By: Anne Fadiman Meghan Maloney 26 April 2013 To understand the struggles that the Hmong people face living in America it is important to understand where they come from and what they have gone through. The majority of the Hmong people originate from the mountainous country of Laos. The mountains created isolation from the neighboring cultures and cultivated a clan identity. They were part of a society where everyone worked together

?What could have happened before? Plenty of years before the actual Jack visited the hotel‚ someone had already been there. The funny thing is that it’s someone who looks like him. Anybody could swear it’s him. But how is it possible? More than 40 years had passed and the man in the picture (who looks like he’s in his mid-forties) was still alive and all‚ visiting the hotel (again)? Some old people living in the town‚ who were relatively close to the hotel owners‚ say that nobody really knew the

Enzymes Abstract: The following 2 labs experimented the more enzymes and substrates added to the concentration will effect the reaction rate. Our second lab‚ we tested enzyme and substrate concentrations to determine the increase of temperature and inhibitor. The enzyme source used in both labs was peroxide‚ guaiacol is used as a substrate for peroxide. We used Guaiacol‚ turnip extract‚ peroxide and distilled water for enzyme and substrate concentration. In the second lab we used the same substances

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

Do Animals Have Any Rights? Should They Be Used For Research? April 18‚ 2013 Do Animals Have Any Rights? Should They Be Used For Research? If you walked in a childrens hospital and seen kids sick and on the verge of dying‚ will you kill ten rats to save those children? is it animal research or animal cruelty? There are over a million animals who die each year such as rats‚ monkeys‚ rabbits and so far because of experimentation‚ and for fashion but there are millions of
