Textbook Question
Chapter 8, Problem 13CC
If you put ouabain, an inhibitor of the Na+-K+ pump, on a neuron and then stimulate the neuron repeatedly, what do you expect to happen to action potentials generated by that neuron?
- (a) They cease immediately.
- (b) There is no immediate effect, but they diminish with repeated stimulation and eventually disappear.
- (c) They get smaller immediately, then stabilize with smaller amplitude.
- (d) Ouabain has no effect on action potentials.

E. Bar Graph
Use the same technique to upload the completed image.
We will use a different type of graph to derive additional information from the
CO2 data (Fig A1.6.2)
1. Calculate the average rate of increase in COz concentration per year for the time intervals 1959-1969, 1969-
1979, etc. and write the results in the spaces provided. The value for 1959-1969 is provided for you as an
example.
2. Plot the results as a bar graph. The
1959-1969 is plotted for you.
3. Choose the graph that looks the most like yours

The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
