The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
The answer is continental drift.
Continental drift is the geological theory that explains how continents move through Earth's surface. All continents were once connected as one supercontinent Pangea. On that supercontinent, many related species, such as llamas and camels, lived together on one location. But after continents spread apart, related species were separated on different continents and adapted to different conditions
Legumes are plants that have nitrogen-fixing bacteria in their roots.
Earth has 78% of nitrogen. So I would say Earth.
I would give them water and when they start swimming it's a proof that they have been alive, after all, how would they start moving if they have been dead
