What is the advantage of homeostasis?
It allows organisms to live in a range of environments.
It allows organisms to avoid a variety of predators.
It allows organisms to blend into their environment
It allows organisms to reproduce at a faster rate

The organism shown in the diagram normally lives in small ponds and streams that contain water with small amounts of salts and other ions.
What would happen to the organism if it was moved to an environment containing distilled (pure--no salt) water?
Salt ions would move out of the organism due to osmosis.
Salt ions would move into the organism due to osmosis.
Water molecules would move into the organism due to osmosis.
Water molecules would move out of the organism due to osmosis.
