potentials are similar in that they are produced by conductance changes due to the opening or closing of channels. Receptor/ Generator Potentials differ from Action Potentials (APs) in that only APs involve the opening of voltage-gated ion channels. The strength of a stimulus can be coded by an increase in the number of APs from a single receptor and an increase in the number of active receptors. The property that allows receptors to code aspects of a dynamic or changing stimulus is fast adaptation

Step 1: The hand holding the the weight in the pendulum will release the weight and allow it to swing forward to hit the car. This is potential energy by the force of motion of the weight on the pendulum. Potential energy is the energy an object produces due to its position. The pendulum swinging is it being in motion therefore it has kinetic energy. The force shown form this could be Applied Force. Applied force is a force that is applied to an object by a person or another object. Step 2: After

Miriam Yanez Physics 018-01 Literature Review 25 April 2012 Biophysics and protein dynamics have shaped our lives when it comes down to advancements in medicine. In living cells‚ proteins are the main components that keep the organism running at its best with every single protein and enzyme having their own function. The discovery of DNA‚ RNA‚ and other protein synthesis became the structures of life in a new perspective in the smallest ways leading to the continuing studies to uncover more

Hepatitis B vaccine ASSIGNMENT In order to address the general questions posed by the case study‚ you will individually research information on the disease(s) caused by a particular microbe and the vaccine that is used for it. Address the following questions for the microbe and vaccine that you have been assigned: 1. a. Describe the typical symptoms of the disease(s) caused by the agent. Hepatitis B can cause acute (short-term) illness and that can lead to loss of appetite‚ diarrhea

Science in the Big City: Exploring Career Opportunities in the Natural and Physical Sciences New York City May 13-18‚ 2014 Students in the Natural Sciences at the University of Houston-Downtown are generally accomplished and motivated students with strong interests in science. However‚ students typically have a very limited perception of the science careers available to them outside of medicine. To educate students as to the array of potential careers available in the sciences (not medicine)

1. A class that I believe was most particularly significant to me is AP Chemistry. Prior to enrolling in the class‚ I was mostly breezing through school without having to put in a considerable amount of time for homework and studying purposes. A few weeks into the course however‚ I had realized that this class was not going to be even close to the ones I have taken before in terms of the rigor and depth of understanding required to succeed. Now that I have finished the course‚ albeit with a B first

Independent Assessment Physics Lab (SL): Cantilever Flexion Cherno Okafor Mr. Ebrahimi SPH4U7 October 21st‚ 2012 Introduction Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence‚ the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an

Test 1 Study Guide 1. Respiration * Respiration * Gas exchange * Necessary because cells require oxygen. * Exchanging O2 and CO2 * Carbon Dioxide is a waste product and must be removed from the body. * Internal respiration = gas exchange at the cellular level. * Oxygen diffuses from the blood into the tissue cells. * External respiration = gas exchange at the alveoli level. * Oxygen from the inhaled air diffuses into the blood in the pulmonary

ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue‚ muscle and bone. Assume subcutaneous tissue has a density of 1060kg/m3 (Hedrick 2003)‚ muscle has a density of 1104kg/m3 (Madjor 2008) and bone has a density of 5065kg/m3 (Hedrick 2003). Give your answer in Mrayls. Please use speed of sound as 1540m/s for tissue‚ muscle and bone In ultrasound‚ Acoustic impedance (Z) is the quantity of measurement of resistance to sound when passing through a medium
