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.

Answer: It is easy to identify a main idea that is directly expressed in the text. Main ideas are often found at the beginning of paragraphs. The first sentence often explains the subject being discussed in the passage. Main ideas are also found in the concluding sentences of a paragraph.
Explanation:
The main political positions adopted by the federalist party and the main positions adopted by the republican party are central government and democracy respectively. The types of people that joined each of the two parties are Alexander Hamilton, John Jay, as federalist and Thomas Jefferson and Aaron Burr as Republican party. Hence, the correct answer is given.
<h3>How did Republican party emerge?</h3>
It was considered informally as the Jeffersonian Republicans, this group of politicians formed in opposition to the policies of Federalists such as Alexander Hamilton, who favored a strong central government. Headed by Thomas Jefferson, whom they assisted to be elected to the presidency for two terms (1801-1809), the Republicans believed in individual freedoms and the rights of states.
