Answer:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.

Explanation:
The clearest demonstration of the flooding of Jesse's potassium ions (K+) into the axons would be that Jesse stops running for a moment.
<h3>What is membrane potential?</h3>
The expression membrane potential refers to differences in the electrical charges in and out of the nerve cell (in this case, the neuron) in order to transmit information through prolongations called axons.
This difference is due to the presence of specialized ion channels in the membrane that allows the selective passage of ions to the interior of the cell or out it, thereby the movement of the potassium ions through axons is fundamental during the membrane potential.
In this case, stopping running would be caused by the K+ ions that flood the interior of the nerve cells, becoming them positive and leading to membrane depolarization.
In conclusion, the clearest demonstration of the flooding of Jesse's potassium ions (K+) into the axons would be that Jesse stops running for a moment.
Complete Question:

Answer: c. iris – controls the pupil
Explanation:
The iris, a structure which is primarily made up of smooth muscles. These smooth muscles surrounds the pupil. The light enters the eye through pupil which is a black hole present in the middle of the eye. It allows the light to strike the retina. It controls the size of the pupil this way it helps in regulating the amount of light entering the eye. The pupil becomes wider in the darkness and becomes narrower when the light intensity is more. These actions are controlled by iris.
