Introduction and Objective The action potential is an impulse of electrical activity. Action potential occurs when a neuron sends messages electrochemically down an axon called a nerve impulse. When a neuron is not stimulated or inactive‚ it is at resting potential. When a neuron is at rest‚ the electrical charge on the inside of the neuron is negative while the electrical charge on the outside of the neuron is positive. The resting membrane potential of a neuron is about -70 mV (mV = millivolts)

Review Sheet Results 7-1 1. What additional skeletal muscles are utilized in an ERV activity? In food expiration‚ abdominal wall muscles and the internal intercostal muscles contract. 2. What was the FEV1 (%) at the initial radius of 5.00 mm? 74% 3. What happened to the FEV1 (%) as the radius of the airways decreased? FEV1% decreased as the airway radius was decreased. 4. Explain why the results from the experiment suggest that there is an obstructive‚ rather than a restrictive‚ pulmonary

Khanya Ramey Tuesday Nov. 24 Intermolecular Forces Intermolecular Forces Lab II. Goal: The central goal of this experiment is to depict the intermolecular forces of four different properties of solubility‚ evaporation‚ viscosity‚ and boiling point. The reason for achieving the goal is so we can further understand solubility‚ Evaporation‚ viscosity‚ and the boiling point of liquids. III. Experimental procedures In this Lab there were four different stations to experiment with‚ my partner and

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by
