Aneuron has received a signal, causing ion channels to open in the cell membrane, letting positively charged ions flow in. this has caused the membrane potential to change suddenly from –70 to +50 millivolts. this will cause a (an) to occur. a) resting stateb) action potentialc) negative charged) positive charge

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.

it should definitely consists of the total amount of the entry which hindered the diary of how most conflictions and opinions in the 1800s experiences.

answer: the ocean

explanation: if you map out 30 n and 40 n latitude, you will get the ocean
