What else can I help you with?
What two factors maintain the unequal distribution of ions while the neuron is at rest?
strangely worded question i guess it is someone's homework. I suppose Factor 1: The neuron membranes have proteins which actively pump ions to create a potential (The Sodium/Potassium Pump) and Factor 2: charged ions slowly leak out through the cell membrane.
Is Ammonium nitrate a polar or nonpolar substance?
Ammonium nitrate is a polar substance. It contains both positively charged ammonium ions and negatively charged nitrate ions, which results in an overall polar molecule due to the unequal distribution of charges within the compound.
What is a polar molecule water methane sodium chloride carbon dioxide?
Water is a polar molecule with an unequal distribution of charges that give it a slight positive and negative end. Methane is nonpolar because it has a symmetrical distribution of charges. Sodium chloride is an ionic compound consisting of positively charged sodium ions and negatively charged chloride ions. Carbon dioxide is nonpolar due to its linear shape and symmetrical distribution of charges.
Atoms with unequal numbers of electrons and protons are called?
It is an ion. If positive a cation. If negative,an anion
Why are ions unstable?
Ions are unstable because they have an unequal number of protons and electrons, leading to an imbalance in their electrical charge. This imbalance causes ions to seek out other atoms to either gain or lose electrons in order to achieve a stable, neutral state.

What about a cell's resting membrane potential is FALSE?
A false statement about a cell's resting membrane potential could be that it does not involve the movement of ions across the cell membrane. In reality, the resting membrane potential is primarily due to the unequal distribution of ions, such as sodium and potassium, across the membrane, maintained by ion channels and pumps.
How does the resting potential of a neuron work?
The resting potential of a neuron is the electrical charge difference across the cell membrane when the neuron is not sending any signals. This difference is maintained by the unequal distribution of ions inside and outside the neuron, with more sodium ions outside and more potassium ions inside. The resting potential allows the neuron to quickly generate and transmit signals when needed.
A charge difference between the interior of the neuron axon and the exterior exists when the neuron is?
When the neuron is at rest, a charge difference known as the resting membrane potential exists between the interior and exterior of the axon. This potential is maintained by the unequal distribution of ions across the cell membrane, with more negative ions inside the cell compared to the outside.
State of an unstimulated neuron's membrane?
An unstimulated neuron's membrane is polarized, with a negative charge inside the cell relative to the outside. This resting membrane potential is maintained by the unequal distribution of ions across the cell membrane, particularly sodium and potassium ions. The neuron is ready to generate an action potential when stimulated.
Do ions have an unequal number of protons?
yes it does
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting, the inside of the cell membrane is more negative compared to the outside due to the unequal distribution of ions. This difference in charge is maintained by the sodium-potassium pump, which actively transports ions across the membrane to establish the resting membrane potential.
What is the value for the resting membrane potential for most neurons?
The resting membrane potential for most neurons is around -70 millivolts. This negative charge inside the cell compared to the outside is maintained by the unequal distribution of ions across the cell membrane, with higher concentrations of potassium ions inside the cell and sodium ions outside.
What are atoms of elements that have an unequal number of protons an electrons?
Ions.
What are charged atoms of elements that have an unequal number of protons?
Ions
Is Ammonium nitrate a polar or nonpolar substance?
Ammonium nitrate is a polar substance. It contains both positively charged ammonium ions and negatively charged nitrate ions, which results in an overall polar molecule due to the unequal distribution of charges within the compound.
In the absence of stimuli all cells in the body maintain a potential difference across the semipermeable membrane in which the inside of the cell is negatively charged in comparison to the outside?
This resting membrane potential is typically around -70mV in neurons, maintained by the unequal distribution of ions across the membrane. Sodium-potassium pumps actively transport ions to establish this potential difference. It is crucial for processes like signal propagation and cellular function in excitable cells.
