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.

battle of survival between farmers and the rabbits during the great depression

before there were tanks, machine guns, windmills, and solar panels, the first civilizations emerged that create the history of humanity which provided the larger context for western civilization. uses of weaponry and technology were used very differently in the ancient civilizations than they are today. relating back to the times of the ancient mesopotamian civilization, technology kept advancing throughout the ancient egyptian civilization into the ancient greek civilization, and then finally the ancient roman civilization. as techniques and strategies were past down from civilization to civilization, each shared its own similarities, as well as varied differences. one trait they had in common was to commit violence and economically overpower one another. technology has ultimately advanced due to the knowledge transferred from generation to generation. uses of sophisticated weaponry and devices have created more opportunity for warfare and improvement in the work place. ancient civilizations became more powerful due to the advancements of technology. technology did not only create the use of violence, but it also the economies grow and become stronger, because production of trading goods rose like never before. the rivers, such as the nile, tigris, and euphrates all flourished, as well as destructed civilizations. each civilization had different uses for these rivers, however, some benefited more than others. when analyzing ancient civilizations, there   are things you must understand
