Explanation:
Just like a building which has different types of openings, so does a cell. These openings also have many different functions just like an opening in a building. A window is an opening which has a function just like a cell. Different openings have different functions.
A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
<h3>
How the neuron get stimulus?</h3>
When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

<h3>What is animal phylogeny?</h3>
The animal phylogeny is defined as the division of the animal kingdom according to groups which are due to the type of tissue and their various body symmetry.
The type of tissue and body symmetry of the various animals of the nine major animal phyla include the following:
