Refer to the table below.
An electrode is inserted into the axon of a neuron and a second electrode is placed in the extracellular fluid surrounding the neuron. A voltmeter connected to the electrodes displays the electrical potential across the axon membrane. A biologist records the voltage displayed on the voltmeter at one-minute intervals for 7 minutes. What movement of ions across the axon membrane occurred in this system between the 1-minute reading and the 6-minute reading?
A.
B.
C.
D.

Refer to the diagram below.
A student draws the diagram above to show a distribution of positive and negative ions on both sides of a cell membrane. The student states that the membrane potential across this membrane is 0 mV. He then states that this membrane can only develop a negative membrane potential if the negatively charged ions migrate across the membrane. Evaluate the accuracy of the two statements.
