If you add less salt to the water, the overall density of the salt water would decrease, making it less dense than the fresh water. As a result, the salt water would no longer sink below the fresh water and they may mix together more easily.
Eventually if heated long enough (and hot enough) all the water would either eat the world or MELT (turning into steam), leaving behind nothing but solid salt behind. This is one way that you can remove salt from sea water in fact.
Adding fresh water to elodea in salt water would cause the elodea cells to absorb more water by osmosis. This would lead to an increase in turgor pressure within the cells, causing them to become firm and potentially burst due to the difference in salt concentration between the cell and the surrounding salt water.
it would die because of the salt particals
The salt would dissolve, which you can reverse by boiling the water.
It would lose salt into the water.
There are certain types of perch that live in salt water, so in that case nothing would happen. However, if a fresh water perch was placed in salt water it would die. There are very few fish that can go between salt water and fresh water and perch is not one of them.
It would die and so would a salt water fish in fresh water.
