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:
The citizens of the Roman Republic governed themselves by gathering at an assembly to elect their officials/leaders.
Explanation:
A group of farmers from the south organized what was called as the Farmer's alliance. They tried to get legislation passed which would help agricultural workers and farmers because they believed that the east coast was just a bunch of elites who were into politics from the money. When they failed, they decided to organize a party which became the Populist party.
The correct answer is C. The Navigation Acts.
These acts forced the colonies to either import using British traders or sell using British salesmen. This enriched British people but impoverished many traders.
