Examples of extreme environments on Earth are hot geysers and oceanic thermal vents‚ Antarctic sea ice‚ and oxygen-depleted rivers and lakes. Organisms that have evolved special adaptations that permit them to live in extreme conditions are called "extremophiles."

1. Temperature: Put some hot water‚ warm water‚ and cold water in three bowls. Just use water from your faucet‚ and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds‚ place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water‚ my finger felt a hot

How Much Gas CHM 151 LL Wednesday: 11:15-2:00 Instructor: Dr. Leary May 1‚ 2013 Introduction In this project we will choose a solid reagent‚ Mg‚ CaCO3‚ or Na2CO3‚ to react with a hydrochloric acid solution‚ HCl. We are going to measure the amount of gaseous product obtained from the amount of gaseous product obtained from reaction. Then compare to theoretical yield‚ Percent Yield=Actual Yield of Gas/ Theoretical Yield of Gas×100‚ based on stoichiometric prediction. The Ideal Gas Law‚ PV=nRT

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

into the gas that fuels our economy. That is what keeps the gas prices high. When gas supplies are short‚ due to an “inability to refine crude oil into gas efficiently‚” prices increase. This is a component of supply and demand economics. In a positive aspect‚ rising gasoline prices do serve a purpose; they curtail usage so that we do not eventually run out of fuel. If gasoline continued to retain its cheap price‚ despite how much was available‚ people may pull up to their favorite gas station

The oil and gas industry is one of the world’s largest‚ complex‚ and expensive industry. The prices of oil and gas are probably the most closely plotted products in the global economy. In this industry there are three main segment of value chain: upstream‚ midstream‚ and downstream. It is evident that energy source play vital input to human activities‚ development‚ and growth of the economy. Hence‚ it is believed that after the industrial revolution‚ accessed clean‚ inexpensive and reliable energy

Oil and Gas PricesOil and Gas 2There are many issues that cause the cost of oil and gas to increase. The main contributing issue to the increasing cost of oil and gas is supply and demand‚ when demand is greater than supply‚ the price of oil and gas will increase. The factors that affect supply include increased demand‚ problems with refineries and pipelines‚ and disruption to supply or threat of disruption to supply.With the increased demand for oil in the United States and other countries such

Introduction: Skeletal muscle is a type of striated muscle that is attached to skeleton to facilitate movement by applying force to bones and joints through contraction. Skeletal muscle generally contract voluntarily when stimulated by the nerve‚ although they can also contract involuntarily at times. Muscle action is controlled by the Nervous System
