Here's the question from my Biology book.
"Paramecium and other protists that live in hypotonic environments have cell membrane adaptations that slow osmotic water uptake, while those living in isotonic environments have more permeable cell membranes. What water regulation adaptations would you expect to have evolved in protists living in hypertonic habitats such as Great Salt Lake? How about those living in habitats where salt concentration fluctuates?"
