ramzy197 · Answer

its in this order 
collecting duct then passive diffusion then concentrate
these are the answers because the asending limb is impermeable to water but collecting ducts are permeable to water and passive diffusion requires no atp and aquaporins dont require atp to work and aquaporins are used to draw water out of the kidneys so it can be reabsorbed by the body
