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.

Answer:
True
Explanation:
A thesis statement provides the idea of what the thesis is going to be in about two sentences.

This way the thesis statement does name the supporting points in the same order that they appear as the paragraphs in the body section. Hence, this statement is true as the supporting argument is presented in the same sequence as it is presented in the body section.
