This describes the ionic distribution across the cell membrane, where sodium (Na+) concentration is higher outside the cell and potassium (K+) concentration is higher inside the cell. This gradient is maintained by the sodium-potassium pump, a vital mechanism for cell function including nerve impulse transmission.
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.
*than
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
No, the result of diffusion is to equalize concentration between two regions, not to maintain a greater concentration inside the membrane. If there is a concentration gradient, molecules will move down the gradient until equilibrium is reached, meaning the concentration inside and outside the membrane will eventually be the same.
Phosphate ions, sulfate ions, potassium ions, urea, uric acid, creatine.
If the Tm for a particular amino acid has been exceeded, all the filtered amino acid will fail to absorb. This will cause the excess to secrete into the filtrate.
The concentration of dissociable OH- ions is a measure of the basicity of the substance. Greater the concentration of hydroxyl ions, greater is it alkaline.
the movement of particles from areas of greater concentration to area of lesser concentration.

A base contains greater OH- ions compared to an acid. Bases are substances that release hydroxide ions (OH-) in solution, whereas acids release hydrogen ions (H+). Therefore, the concentration of OH- ions is higher in a base, making it alkaline.

The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.
When comparing two solutions, the solution with the greater concentration of solute is called hypertonic. This means that it has a higher solute concentration compared to the other solution.
A hypertonic Solution. a solution that has a greater concentration of water than the cell content is hypotonic, meaning there is less concentration of water inside the cell, which results in an increase or an expansion of the cell.
