Question

a person drinks a six - pack of soda and has to make several trips to the bathroom. this increase in urination reflects an increase in what membr transport process occurring in the kidneys?

dialysis

filtration

active transport

osmosis

Explanation:

• Dialysis is a medical treatment (not a normal kidney process here).
• Active transport requires energy and is not the main process for increased urination from drinking a lot.
• Osmosis is the movement of water across a semi - permeable membrane, but filtration is the key process in the kidneys for forming urine. When a person drinks a lot (like a six - pack of soda), the kidneys filter more fluid. Filtration in the kidneys (in the glomerulus) is the first step in urine formation where fluid is forced out of the blood into the nephron based on pressure. An increase in fluid intake leads to an increase in this filtration process, resulting in more urine (more trips to the bathroom).

Answer:

filtration
