which best describes dynamic equilibrium? there is a difference in concentration on either side of the cell membrane. there is an uneven distribution of particles inside and outside the cell. particles are moving into and out of the cell, but their concentrations remain stable. a concentration gradient is forcing water out of the cell and particles into the cell.
Answer
Brief Explanations:
Dynamic equilibrium in cell - membrane context means particles move in and out, but overall concentrations don't change. The first two options just describe non - equilibrium concentration differences. The fourth option describes a non - equilibrium situation driven by a concentration gradient.
Answer:
Particles are moving into and out of the cell, but their concentrations remain stable.
