B particles from a region of lower concentration to a region of higher concentration using
energy from respiration.
C urine by relaxation of a sphincter muscle in the bladder.
D water through a partially permeable membrane from a more dilute to a more concentrated
solution.
112. The diagram shows an experiment to demonstrate the movement of molecules.
