Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

mealworms to the nearest tenth. Then use the wire rod to push the small piece of cotton into the first tube. After the cotton‚ put the mealworms into the tube. Put another piece of cotton behind the mealworms. The cotton has to be loose enough so that air can pass through‚ but tight enough that the mealworms cannot pass through. Put another small piece of cotton behind the second piece and leave about 2cm in between it and another piece

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

power generation‚ heat is lost‚ which is used to increase the internal energy of the fluid‚ water in this case‚ through the exchangers. Hot water is either directly pumped to the end user during the winter season of the year or it is used to power refrigeration cycles through the Absorption Chiller during the summer. The production of chilled water turns the system into a tri-generation process and is called CHPC ‚ which stands for combined heat‚ power and chilling system. Control and temperature sensors

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

processing but the type of quality of the processing that is performed‚ that determines the retention. The aims of this study were to empirically replicate and understand Craik and Tulving’s levels of processing theory and how it influences memory. It was hypothesized as the level of processing increases‚ hit (yes responses) proportion will also increase. Also hypothesized that if in the study phase required a yes response‚ it would be more likely remembered. Method Participants 52 participants enrolled

Unit 10 Lab 1 1. ZenMap GUI sends out broadcasts for server queries for various different types of operating systems in servers (OS). By examining how various hosts respond to certain queries‚ ZenMap GUI can distinguish what kind of OS and server exists. 2. Nmap searches its internal database and what ports on the IP’s are listening and matches it to the best known application. Applications like MSSQL and Web servers usually use the same ports over and again For example tcp port 3389 will most definitely
