If there is more sodium inside a cell than outside which process could the cell use to take more sodium?
The cell could use active transport to move sodium against its concentration gradient from outside the cell to inside the cell. This process requires energy in the form of ATP to pump sodium ions against their concentration gradient.
How do sodium ions move during resting potential?
During resting potential, sodium ions are actively pumped out of the cell by the sodium-potassium pump to maintain the concentration gradient. This helps to establish a more positive charge outside the cell, contributing to the negative resting membrane potential inside the cell. Sodium channels are closed during resting potential, preventing sodium ions from moving back into the cell.
Why is sodium dried before ignition?
Sodium is dried before ignition to remove any moisture that could interfere with the reaction or cause splattering when it ignites. Water can react with sodium to produce hydrogen gas, which can lead to an unpredictable and potentially hazardous situation. Drying sodium helps ensure a more controlled and safer ignition process.
Which one is more malleabe iron or sodium?
Sodium is more malleable than iron. Sodium is a soft, highly malleable metal that can be easily flattened into thin sheets with a hammer or a rolling process. In contrast, iron is not as malleable as sodium and requires more force to shape into thin sheets.
How does the sodium potassium pump operates?
The sodium-potassium pump functions much like a revolving door. Its main job is to keep sodium ions (NA+) outside of the cell and keep potassium ions (K+) inside of the cell. With the addition of energy from an ATP molecule, the sodium potassium pump moves three sodium ions out of the cell and moves two potassium ions into the cell with each turn. The goal of this process is to return, or keep, the cell at a resting state, or resting potential.

Is there more sodium inside a cell than outside which process could the cell use to take in more sodium?
Active transport moves a substance across a membrane UP it's concentration gradient.

The repolarization phase of the action potential where voltage becomes more negative after the plus 30mV peak?
During repolarization, potassium channels open and potassium ions exit the cell, causing the inside of the cell to become more negative. This process restores the cell's resting membrane potential. It follows the depolarization phase, where sodium channels open and sodium enters the cell, causing the inside of the cell to become more positive.
What direction cell to cell water movement occurs?
It would depend on what is in the water. If there is more sodium (Na) in the water than in the cell, water will move out of the cell. The cell will become limp or crenate. If the opposite is true, the cell will swell and could burst. A good rule of thumb is "water follows salt (NaCl)". This means that wherever there is more salt, water will follow.
Are Excitable cells like neurons are more permeable to sodium than to potassium?
Yes, excitable cells like neurons are more permeable to sodium ions than potassium ions. This selective permeability is due to the presence of more sodium channels compared to potassium channels in the cell membrane, allowing sodium to flow into the cell more readily during an action potential.
If the sodium channel or the fast calcium channels are open the inside of the cell would be relatively more what?
If the sodium channels or fast calcium channels are open, the inside of the cell would become more positively charged due to the influx of sodium or calcium ions. This would depolarize the cell membrane and initiate an action potential, leading to nerve or muscle cell activation.

Are cells separated during the process of mitosis?
Yes. Mitosis is the process of cells separated or dividing to create more cells. this could be dangerous if a cell is mutated and it goes through mitosis producing more mutated cells.
