I need help with this one bio question =P
Many marine invertebrates have body surfaces that are permeable to water but not to salt. Osmosis can change the pressure of their body fluids. Fortunately, the ocean is very stable in its salt content. What would happen if a jellyfish were placed in a very low-salt environment such as an estuary?
A) It would gain nutrients from the water in the environment
B) It would lose proteins into the water
C) It would lose salt into the water
D) It would gain water from the environment

D, osmosis is the net movement of water molecules from a region of high water concentration to a region of low concentration. The low salt environment means that the is a lot of water molecules, so osmosis balances this out so it gains water.
Hope this helps :-D
