Neurоn Actiоn Pоtentiаl - Pаrt 2 This question is аbout what triggers the voltage-gated ion channels to open and close during an action potential. Take a look again at the graph of an action potential on the membrane of a neuron (given below). Describe what is happening in the voltage-gated sodium channels and the voltage-gated potassium channels during the point in time on your graph 1) when threshold is reached, 2) when +30mV is reached, and 3) when -80mV is reached. What are each of the two ion channels doing at each of these 3 points on the graph? Tip: remember that sodium channels have two gates and three states, whereas potassium channels have one gate and two states.
A nаtiоnаl pоlling оrgаnization does a survey of 995 people to estimate the percentage of all American adults who favor a ban on the use of cell phones while driving. In the survey, 37% said they favor such a ban. a.) Find a 99% confidence interval for the proportion of all American adults who favor such a ban. Also find the margin of error. Round your answers to four decimal places. 99% Confidence Interval: ( [LL] , [UL] ) Margin of Error: [E] b.) Still using a 99% confidence interval, how many should be polled to reduce the margin of error to 2%? Use the fact that in the first poll 37% said that they favor such a ban. Required sample size = [n]
