Question

when the net movement of water in and out a cell is zero, that solution is said to be
isotonic
osmotic
hypotonic
pressurized
hypertonic

Explanation:

In an isotonic solution, the solute - concentration outside the cell is equal to that inside the cell. This results in no net movement of water across the cell - membrane as the osmotic pressure is the same on both sides. Osmotic refers to the general process of water movement across a semi - permeable membrane. Hypotonic solutions have a lower solute concentration outside the cell, causing water to move into the cell. Pressurized is not related to this context. Hypertonic solutions have a higher solute concentration outside the cell, causing water to move out of the cell.

Answer:

A. isotonic
