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

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention
