Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of
VMariaS [17]

Answer: positive sodium ions

Explanation:

This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.

The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

Microtubule – serves as a framework of the cell –cytoskeleton.<span>

Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>

Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.
