Question

what would most likely happen to a unicellular organism if it was exposed to a hypotonic solution for an extended period of time? it would shrink and shrink. it would swell but never burst. it would swell and then burst. it would not be affected.

Explanation:

In a hypotonic solution, the solute concentration outside the unicellular organism is lower than inside. Water will move into the cell by osmosis. As a unicellular organism has no cell - wall (in many cases like animal - like protists), it will swell and if the influx of water is excessive, it will burst.

Answer:

It would swell and then burst.
