Which of the following structures is responsible for osmoregulation?
Answer Details
Structure II is responsible for osmoregulation. Osmoregulation is the process by which organisms regulate the concentration of water and solutes in their cells to maintain internal balance or homeostasis. Structure II is most likely a cell or an organ that is involved in this process. The other structures may have different functions such as support, protection, or movement, but they are not directly involved in osmoregulation.
