The <u>Ion Channels of membrane</u> facilitates unequal distribution of polar and charged molecules on two different sides of membrane.
The traveling wave of electrical excitation, known as an action potential/nerve impulse, can carry a message without attenuation from one end of a neuron to the other as speeds as great 100m/sec or more.
The voltage is an electrical potential energy that is caused by the separation of opposite charges, in the case of across membrane.
It is so because a membrane potential arises when, there is a difference in electrical charge on both the sides of a membrane, due to a slight excess in positive ions over negative ones on one side and a slight deficit on the other.

Explanation:
Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
