Continuous change: This option suggests ongoing change without reaching a state of balance, which does not accurately describe dynamic equilibrium.
Nonchanging internal conditions: This option implies a static state with no change, which is not the case in dynamic equilibrium where changes are ongoing but balanced.
Balanced change: This is the correct description of dynamic equilibrium. In dynamic equilibrium, the rate of forward change is equal to the rate of reverse change, resulting in a stable system where conditions appear constant despite ongoing processes.
Summary:
Dynamic equilibrium refers to a state where changes occur continuously but are balanced, maintaining a stable condition overall.
