Answer 1

the tad poles will die

Answer 2

If frog eggs are taken from a freshwater lake and are set in a saltwater aquarium, the frog will die.

This is on the grounds that when the frog eggs are put in the saltwater aquarium, the water goes from a higher to a lower concentration and in the end the water inside the eggs clears out.
