What else can I help you with?
If there is more solute inside a membrane than outside solute particles will move across the membrane to the?
equalize the concentration on both sides of the membrane through passive diffusion.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
What is the process of water diffusing across a what membrane?
Water diffuses across a cell membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high water concentration to an area of lower water concentration, driven by the concentration gradient of solutes across the membrane. This process helps maintain the cell's internal environment and balance the concentration of solutes inside and outside the cell.
How does osmosis explain the movement of water across cell membranes?
Osmosis is the movement of water from a solution of high concentration to a solution of lower concentration through a membrane. Water passes through the membrane, diluting the solution of higher concentration on the other side, until both solutions on either side of the membrane have equal concentrations.
There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.

Is the movement of water to try to balance concentrations?
Osmosis, which is the movement of water across a semi-permeable membrane from where it is in high concentration to where it is in lower concentration. The purpose of osmosis is to equalize the concentration of solutes inside a cell and outside a cell.
What is the process which water moves across the cells membrane?
Water moves across the cell membrane through osmosis, which is the passive movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane. Osmosis helps maintain the balance of water and solutes inside and outside of the cell.
There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.
What best describes the Na plus and K plus concentrations across a neuron's plasma membrane?
Na+ concentration is higher outside the neuron than inside, while K+ concentration is higher inside the neuron than outside. This concentration gradient is maintained by the Na+/K+ pump, which actively transports Na+ out of the cell and K+ into the cell, contributing to the resting membrane potential of the neuron.
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 concentration of solutes is equal the concentration of solutes inside the cell?
when a concentration of something, usually water, is the same inside and outside a cell, it is called an isotonic solution. When there is more inside the cell or membrane, but less outside, the solution is hypotonic. when there is more on the outside , it is known as hypertonic. however, it depends what you are describing
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when?
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when it is against the concentration gradient, a process known as active transport. Energy is needed to move the molecules from an area of low concentration to an area of high concentration.
In diffiusion movement of particles across a membrane is drven by what differences?
In diffusion, movement of particles across a membrane is driven by differences in concentration gradients, which is the difference in concentration of a substance on either side of the membrane. Particles naturally move from areas of higher concentration to areas of lower concentration until equilibrium is reached.
