Sponges grow in the ocean. If a live sea sponge is placed into a glass of pure (100%) water,what will immediately happen
- water will move in and out of the sponge's cells at an equal rate
- water will not move across the sponge's cell membranes
- water will move into the sponge's cells causing it to swell
- water will move out of the sponge's cells causing it to shrink
