Acids and Bases Shane Purpose- To study the relationship between pH and metabolism. 10/21/13 Materials- see attached Per. D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic

Biological Bases of Behavior Nervous System Made up of neurons‚ which are the nerve cells. These send electrical impulses to one another ( through a process known as firing) telling the body what to do. The parts of a neuron include: Cell Body (a.k.a. soma) – Main part of neuron; contains basic cell parts such as nucleus‚ ER‚ etc.; also has dendrites extending from it. Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension

TWO-BASE EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different
