No spamming

Answer 1

hi

They would be hypertonic to freshwater, so water would move by osmosis into the fish's cells. Conversely, if a freshwater fish were put in a saltwater aquarium, its cells would be hypotonic to the saltwater. They would lose water and shrivel.

Answer 2

If marine if kept in fresh water the will die
BECAUSE the contains more salty in their body if their in fresh water fresh water doesn't contain salt so it will not match so if we keep in salty water it will match so fish will die when it is placed in freshwater
So I hope it helps you
