Draw an action potential on a graph showing the x-axis and y-axis with proper labels and numbers (the numbers are approximate as they may vary slightly from neuron to neuron). A. Describe the ionic conductances that underlie the action potential including gating of the specific ion channels at threshold, rising phase, falling phase and the undershoot phase. Explain threshold, absolute refractory period and relative refractory period in relation to the action potential. B. C. Sodium and potassium currents demonstrate very...

Use what you know about the physiology of neurons to answer the following questions. Treat each of these questions as unrelated to each other. a. Imagine that a mutation makes Na* leak channels just as common as K' leak channels. Explain the effect of this mutation on the resting potential of this neuron. 3. b. The intracellular:extracellular ratio of K' ions is normally 150:4mM. Imagine that you decrease that ratio to 150: 20mM. Describe the subsequent effect on the resting...

(20 pts.) Draw each question (a-d) on a separate set of axes. Be sure to label all axes, directions, planes, etc. appropriately. a. (5 pts.) Draw the following crystallographic directions in a cubic unit cell: [112],[010], [100]. b. (5 pts.) Draw all directions in the family <110> in a cubic crystal on a single set of axes. C. (5 pts.) Draw the following planes in a cubic unit cell: (110), (112), (010). d. (5 pts.) Draw all the planes in...

1. Draw a set of EPSPs and IPSPs that will initiate an action potential. You must use at least 4 IPSPs to reach threshold and initiate an action potential. Use a normal action potential graph as an example. Each EPSP is +6 mV and each IPSP is -2 mV (I totally made these numbers up). You can put the EPSP and IPSP in any order, alternating or, however. Resting potential is -70mV and threshold is -50 mV. An example of...

NAME (PRINT For each question, first draw a demand curve. label it D1. This is the initial condition. Then, in response to the situation posed, show how (if it does) the demand curve shifts on the same chart. Label the new demand curve D2. You must properly label the axes to get all points possible. Each question is worth 2 points. 1. The government announces that oranges are full of cancer-causing chemicals. Show what happens to the demand curve for...

For each of the following examples, draw a representative isoquant. Make sure to label the axes. Explain briefly why you drew each isoquant the way you drew it. a) A firm finds that it can always trade two units of labor for one unit of capital and still keep output constant, regardless of how many units of labor or capital have already been used. b) A firm needs either cats or dogs to produce its output. Cats and dogs don’t...

For each of the following: draw a supply/demand graph for the currency market in question. Label axes, the supply and demand curves, and equilibrium exchange rate. Then show and explain with words what will happen to the market after the shock described. Include the effect on the foreign exchange rate. Explain. the market for Mexican Pesos - investors speculate that the Peso will soon appreciate the market for British pounds - Brexit scares investors, so investors leave the UK the...
