A Place at the Table There are different versions of the American dream whether it is for justice or for an escape. In this short documentary‚ it talks about the different experiences of 8 individuals who dug deep into their family’s migration stories. Almost every single one of the story tellers said that the American dream that their parents or grandparents were chasing after was a place or a dream to escape. They were either trying to escape their harsh environment‚ or trying to build a different

Abstract The major objective of this experiment was to observe the effects of catalase under varying controlled conditions. The scope of this experiment includes Metabolic processes‚ such as cellular respiration‚ and it poisonous byproduct hydrogen peroxide. The methodology includes procedures; multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen

Abstract This practical was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent

Cindy Hoang-Tran Professor Ducat English 101 13 Dec 2012 Gas Fracking Natural gas is extremely useful in our lives. We need natural gases to heat our houses and use microwave ovens‚ conventional ovens and stovetops. Because the economy currently isn’t well off – and hasn’t been recently – natural gases are now in higher demand for cheaper prices. Oil and gas drilling facilities are now making it possible for natural gases to be sold at extremely cheap prices and accessible amounts through the

CONCENTRATION - The Tunnel Vision Of Mind. Concentration is the art of being focused at what one is doing without permitting any form of hindrance. It is an essential skill that every individual develops as he/she grows up. It has to be developed by one’s own effort and cannot be injected into one’s mind. Of course‚ at times‚ people may guide them as to how to gain concentration‚ but the key to having full concentration is in our hands.

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration would

Facts of the periodic table While Dmitri Mendeleev is most often cited as the inventor of the modern periodic table‚ his table was just the first to gain scientific credibility‚ and not the first table that organized the elements according to periodic properties. There are 90 elements on the periodic table that occur in nature. All of the other elements are strictly man-made. Technetium was the first element to be made artificially. The International Union of Pure Applied Chemistry‚ IUPAC‚ revises

Effects Of Smoking On The Mammalian Gas Exchange During the First World War‚ a lot of men started smoking and more women started smoking too during the 1940s and 1950s. Years later‚ it became apparent that certain diseases‚ such as chronic bronchitis‚ emphysema and lung cancer became a lot more common. Cigarette smoke contains over 4000 different chemicals. Many of these are harmful‚ including tar (a mixture of chemicals including carcinogens‚ which cause cancer)‚ carbon monoxide and nicotine
