Question

question 7
cells in an isotonic solution, have no net flow of water show a state of

o a active transport
o b hyposalinity
o c hypertonicity
o d dynamic equilibrium

Explanation:

In an isotonic solution, the solute concentration is the same inside and outside the cell. There is no net movement of water across the cell - membrane. This represents a state of dynamic equilibrium where water molecules are moving in and out of the cell at the same rate, but there is no overall change in the cell's volume or water content. Active transport involves the movement of substances against a concentration gradient using energy. Hypotonicity refers to a solution with a lower solute concentration than the cell, causing water to move into the cell. Hypertonicity refers to a solution with a higher solute concentration than the cell, causing water to move out of the cell.

Answer:

D. dynamic equilibrium
