Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction. a. Between the attempts to diffuse glucose and albumin through the 200 MWCO membrane‚ the results for both were that glucose was diffuse but the albumin did not. Comparing to my prediction‚ the results were a bit different. I predicted that both were able to diffuse‚ but at the end‚ only glucose diffused. 4. Put the following in order from smallest

Why don’t the terms depolarization and action potential mean the same thing? They require different things. Action potential requires depolarization and repolarization. Depolarization doesn’t require anything. 2. What was the threshold voltage in Activity 1? 3.0V 3. What was the effect of increasing the voltage? How does this change correlate to changes in the nerve? The action potential increases. 4. How did the action potential generated with the unheated rod compare to the that

PhysioEx 9.0 Exercise 3 Neurophysiology of Nerve Impulses A C T I V I T Y 1 The Resting Membrane Potential 1. Explain why increasing extracellular K_ reduces the net diffusion of K_ out of the neuron through the K_ leak channels. Increasing the extracellular potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

extracellular K+ the membrane potential will change to be a less negative value. By adding more extracellular K+ the intracellular K+ will decrease and cause the membrane potential to become less negative. This result in a increased postitve membrane was what we predicted during the experiment. 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? Your answer: A change in the extracellular Na+ did not significantly alter the membrane potential

bell curve is literally‚ the symmetrical curve created on a graph when using a frequency distribution method for a set of data‚ splitting the mean symmetrically. There is a big difference between standard deviation and the bell curve! Standard deviation shows the difference in variation from the average; the bell curve‚ also normal distribution or Gaussian distribution‚ shows the standard deviation and is created by the normal or equal distribution of the mean among either half. The bell curve is an

Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry
