Which ions electrical charges oppose the direction of movement that is caused by their concentration gradient?
Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell. Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell.
What is one in which the concentration of dissolved materials in the water outside the cell is lower than the concentration inside the cell?

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.
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.
A resting potential is caused by a difference in the concentration of certain ions inside and outside the cell?
True
What is isotonic concentration?
Isotonic concentration is when the concentration of soletutes inside and outside of the cell are equal in concentration
The concentration of material is greater on the outside of the cell than the inside in what solution?
A solution in which the salt concentration is greater outside the cell than inside the cell is known as
The inside of cells have a higher concentration of what?
The inside of cells have a higher concentration of Potassium. But there's a higher concentration of Sodium outside the cell.
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.
Which ions electrical charges oppose the direction of movement that is caused by their concentration gradient?
Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell. Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell.
What takes place during osmosis?
Osmosis is the movement of water form its higher concentration to lower concentration through a semi permeable membrane. In it water can move from inside to outside or outside to inside.
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
A cell is in what when solute concentration inside and outside the cell are equal?
Isotonic.
A cell is in when solute concentration inside and outside the cell are equal?
Isotonic.
What is one in which the concentration of dissolved materials in the water outside the cell is lower than the concentration inside the cell?

What role did diffusion play in the changes you observed?
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
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.
