Mascarano Biology Lab Fall 2014 Determining the properties of an enzyme Abstract: To determine the properties of an enzyme, a peroxidase, turnip extract is used in this experiment Enzymes are large proteins that are responsible for the speed at which chemical reactions they are involved in taking place. Enzymes speed up chemical reactions by lowering the activation energy of a reaction, the amount of energy necessary to trigger a reaction .Using Peroxidase ,Turnip extract which is expermitnatal easy to prepare and examime that is This experiment determines the effects that concentration temperature, ph, boiling have on an enzymes ability to perform its work. It is hypothesized that none of these variables will have any effect on the activity of the enzyme. Introduction : This expermient with present various temperates and ph levels to be teste in order to determine the properties of an enzyme. An enzyme is a protein that acts as a catalyst, that changes the rate of a reaction with no help of energy. Enzymes lower the activation energy of a reaction the amount of energy necessary to trigger a reaction. Most enzymes are proteins that have a unique shapes which are determined by their amino acid sequences.The shape of the enzyme called the active site determines its catalytic effects. The active site of each type of a unique shape that allows the enzyme to bind with only certain kinds of enzymes called the...

...Exercise 1. Part 1) How does a class being conducted online instead of on campus increase or decrease the classes' contribution to the carbon cycle during the term? Consider the differences between the two in terms of methods of travel, and use of facilities, energy, and other resources. Remember to focus on the impact to the carbon cycle. Part 2) Complete the ecological footprint quiz at the following link: http://myfootprint.org/en/visitor_information and report your results. What did you learn about you and your family's impact on the environment? • Part 1) We decrease the distribution to the carbon cycle by being in online classes, because the burning of fossil fuels increase the amount of CO2 being distributed into the air. Being in online classes keeps one indoors to do their classwork and participate. • Part 2) My carbon footprint is 59.47, My food footprint is 76.46, My housing footprint is 34.17, My goods and services footprint is 21.15. If everyone in the planet lived my lifestyle, we would need 4.95 earths. After doing this quiz, it showed me that I need to start recycling a little more and buying products that would be better for me and the environment specially when it comes to the foods I eat, I need to eat more healthier and spend less on fast food items which is something me and my family frequent every weekend. I did not know just the little things I do could effect the environment so much. Exercise 2. Using ONE ecosystem from the list below, explain the role...

...Chemical and Mechanical Weathering of Rock Lab Lauren Templeton, Heather Mullen, Katherine Welmaker, Becca Gojda 2 October 2015 Abstract This lab explores several different forms of weathering and the specific effects they have on rocks. Mechanical Weathering was found to reduce the weight of different types of rocks more efficiently than others. Geological Changes were found to make small physical changes to the exterior of the rock. Glacial Changes were found to affect the ground through the the sand the “glacier” moved around. Chemical Weathering was found to quickly dissolve the marble but not the granite. Oxidation was found to dissolve the pyrite very quickly and continue to dissolve it over the next 2-3 days. Organic Processes were found to have a major physical effect on the paste as it broke it apart. Materials Bean Seeds, 10 Magnifying glass Calcium sulfate, CaSO4, 2 spoonfuls Marker Granite chips, 20 g Paper towels Halite chips, 15 g Pipets, Beral, graduated Hydrochloric acid solution, HCl, 1 M, 15 mL Plastic cups, small, 3 Ice cube Sample container...

...CHEM 321 Experiment 1 Basics Review and Calibration of Volumetric Glassware There are three types of containers used in lab to contain or deliver liquids: volumetric, ordinary, and disposable glassware. Volumetric glassware are containers that have been calibrated at a specific temperature to deliver or contain VERY PRECISE amounts of liquid. Examples of volumetric glassware that we will use include burets, pipets, and volumetric flasks. Ordinary glassware has less precise volume calibrations and are used whenever the volumes do not have to be measured as accurately. Examples include beakers, Erlenmeyer flasks, and graduated cylinders. Disposable glassware (or plastic ware) is used to transfer or hold liquids temporarily and may not contain any volume markings. Examples include medicine droppers and disposable pipets. In this experiment you will be exposed to a variety of important concepts related to quantitative experimentation, including the proper use of glassware, analytical balances, and statistics. You will calibrate a volumetric pipet or flask, that is, you will experimentally determine what volume a pipet or flask really delivers. You will also calibrate a beaker or Erlenmeyer flask and a 50 mL buret. You will use these calibrated values throughout the remainder of the quarter. Construct a table at the front of your laboratory notebook to record calibration values or tape in the calibration tables from Chapter 2 of Harris’ 7th edition. How to read the level of liquid...

...Observing the living creatures around us Jemyla bell AIU Online Biology IP.1 Question When taking a hike, you notice that a ruby-throated hummingbird seems interested in your red hat. It hovers over the hat and then darts away. Do ruby-throated hummingbirds prefer some colors more than others when visiting flowers? Observing the living creatures around us There is a saying that ruby-throated hummingbirds are attracted to preferred colors curiosity struck me when I noticed the hummingbird taking interest in my red hat, very interested in knowing the truth for myself I decided to conduct an experiment to find out whether ruby-throated hummingbirds are attracted to some colors more than others. According to (Suarez & Gass, 2002) she believe that ruby-throated hummingbirds may be attracted to some colors like red. I then decided to test the theory for myself by measuring the time and frequency of the hummingbird’s attraction by testing a series of colors. By doing this experiment it should reveal rather the ruby- throated hummingbird is attracted to red or a series of colors. Hypothesis I predict that ruby-throated hummingbirds will be attracted to the red color more verses the others Colors. Prediction: During this experiment I expect to obtain accurate results based on the use of my experimental method to find out if the ruby-throated hummingbird is more attracted to red verses other colors. I expect to prove that bright colors like red attract...

After receiving a Harvard Book Award and a National Achievement Scholarship at University City High School, he entered Princeton University in 1973. There, he encountered his first real introduction to research mathematics in an honor calculus course taught by the late Ralph Fox. He wrote his undergraduate senior thesis, titled "Galois Connections on Local Fields,'' in algebraic number theory, under the direction of the late Bernard Dwork, and graduated from Princeton in 1977 with an A.B. in Mathematics (Magna Cum Laude, Phi Beta Kappa, and Sigma Xi). That same year he was awarded a Bell Labs Cooperative Research Fellowship for minorities to attend graduate school in the department of mathematics at Stanford University. In 1981, he received his Ph.D. degree from Stanford and his thesis, titled "Non-Stationary Queues,'' was directed by Joseph Keller. Dr. William Massey's parents, Juliette and Richard Massey Sr. were both educators; she was from Chattanooga, Tennessee and he was from Charlotte, North Carolina. They met at Lincoln University in Jefferson City, Missouri which became his birthplace.

They were previously known as AT&T Bell Laboratories and Bell Telephone Laboratories is now the research and development subsidiary of the French-owned Alcatel-Lucent. Over the past eight decades, Bell Labs R&D gave birth to new technologies and seminal scientific discoveries. (Alcatel Lucent, para 1) Elisha Grey and Enos N. Barton formed Western Electric Company in 1869. Both of them started a small manufacturing firm based in Cleveland, Ohio which was to become the largest electrical manufacturing company in America. In 1881, Alexander Graham Bell, an extraordinary leader of American Telephone & Telegraph (AT&T), purchased a controlling interest in Western Electric and made it the exclusive developer and manufacturer of all equipments for the Bell telephone companies. Now, the Bell system has provided much telephone services and support to America and Canada in the 1877 to 1984. It was then led by AT&T. In 1898, Compagnie Générale d'Electricité (CGE) was born, founded by a French engineer named Pierre Azaria. It was involved in business with several industries in Germany. Mainly it dabbled in electricity, transportation, electronics and telecommunications.

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...
