Since the proximal convoluted tubule reabsorbs molecules by diffusion, what structure would you expect to find at the microscopic level?
A) microvilli to increase surface area
B) smooth muscle to stretch as the volume inside increases
C) numerous mitochondria to allow active transport
D) loose connective tissue so that liquids can pass through the cells
E) many neurons to stimulate the cells to reabsorb
