What causes the inside of a neuron to be negative?
The inside of a neuron is negative due to a higher concentration of negatively charged ions, particularly chloride and proteins, compared to the outside of the neuron. This difference in ion concentration creates a resting membrane potential, which is maintained by the sodium-potassium pump and ion channels in the neuron's cell membrane.
The concentration of material is greater on the outside of the cell than the inside in what solution?
The concentration of material is greater on the outside of the cell than the inside in a hypertonic solution. In this solution, there is a higher concentration of solutes outside the cell compared to inside, causing water to move out of the cell, leading to cell shrinkage.
The inside of cells have a higher concentration of what?
The inside of cells have a higher concentration of potassium ions compared to the outside of the cell. This concentration gradient is maintained through the action of ion channels and pumps in the cell membrane.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What ions is in high concentration inside the neuron?
Potassium ions (K+) are found in high concentration inside the neuron compared to outside. This concentration gradient is maintained by the sodium-potassium pump.
Is resting potential caused by a difference in the concentration of certain ions inside and outside the cell?
True
What causes the inside of a neuron to be negative?

What is an example of a concentration gradient?
An example of a concentration gradient is the difference in the concentration of ions inside and outside a cell membrane. This difference creates an electrical potential that drives processes such as ion transport and nerve cell signaling.
The concentration of material is greater on the outside of the cell than the inside in what solution?
The concentration of material is greater on the outside of the cell than the inside in a hypertonic solution. In this solution, there is a higher concentration of solutes outside the cell compared to inside, causing water to move out of the cell, leading to cell shrinkage.
Is there a difference between an inside and outside barrel?
No, there is no difference between an inside and outside barrel. Doran is an idiot
Based on diffusion what will happen to the substances inside and outside of the cell?
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
If substance A could defuse across the membrane what would happen to the concentration of A inside the cell and outside the cell?
If substance A can diffuse across the membrane, it will move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This means that the concentration of A inside the cell will increase while the concentration outside the cell will decrease, assuming that the initial concentration outside the cell is higher than inside. Eventually, the concentrations inside and outside the cell will become equal if no other factors interfere.
What is the state when an electrical charge of a neuron is said to be at a resting potential?
The resting potential is the normal equilibrium charge difference (potential gradient) across the neuronal membrane, created by the imbalance in sodium, potassium, and chloride ions inside and outside the neuron.
The inside of cells have a higher concentration of what?
The inside of cells have a higher concentration of potassium ions compared to the outside of the cell. This concentration gradient is maintained through the action of ion channels and pumps in the cell membrane.
How are cells in sodium chloride different from distilled water?
Cells in sodium chloride will experience shrinkage (crenation) due to the higher concentration of salt outside the cell than inside. In distilled water, cells will swell and potentially burst (lyse) due to water entering the cell to equalize the concentration of solutes.
What is the main difference between the inside and the outside of bone?
The main difference between the outside and inside of bone is; the inside of a bone is bone mallow, whereas the outside of a bone is covered by flesh.
