(Select all that apply.) Active transport of ions out of the proximal convoluted tubule Active transport of ions into the proximal convoluted tubule Collecting ducts that do not absorb water Distal convoluted tubule that does not absorb water Passive transport of ions out of the distal convoluted tubule.
