Answer:
B) action potential
Explanation:
The ions continuously flow across the cell membrane in the cells which establishes a membrane potential across the membrane. The cell membrane tries to maintain the negative potential between -40 to -90 mV.
At rest the neuron cell maintains the membrane potential around -70mV and this potential are known as the resting potential.
When the positive ions especially sodium ions enter the neuron then the positive charges get accumulated inside the cell. This changes the potential to a more positive value and when it crosses the threshold of -55mV then an action potential is formed.
In the given question, if the membrane potential changes from –70 to +50mV then an action potential will be generated in the neuron cell.
Thus, B) action potential is the correct answer.
<span>Slavery had come to America in 1619. It existed through the American Revolution, even after Thomas Jefferson penned his famous lines in the Declaration of Independence, "All men are created equal. They are endowed by their creator with certain unalienable rights. That among these are life, liberty, and the pursuit of happiness." Obviously, slaves were not part of this equation. When it came time to write the Constitution, the word "slavery" was never used. Instead, the framers chose to use the term "other people." These other people were counted as 3/5 of a person for the purposes of representation in Congress according to the 3/5 Compromise. This compromise kept slavery in the United States intact. The founders also decided not to do anything about the issue of slavery for twenty years. Someone else would have to deal with it.</span>
<span>In 1820 with the admission of Missouri to the Union, the issue of slavery came up again. There was already a great deal of tension between the North and the South. The South was highly agricultural. It wanted to keep slavery as a way of life on their plantations. The North, which was</span>
