Question

1. what would happen to a cell if it was placed in extremely salty water?

Explanation:

Extremely salty water has a higher solute (salt) concentration than the cell's interior. By osmosis, water moves from the cell (low solute, high water) to the external solution (high solute, low water). This causes the cell to lose water, shrink, and potentially become plasmolyzed (in plant cells) or shrivel (in animal cells).

Answer:

The cell would lose water via osmosis, shrink (and may become plasmolyzed in plant cells or shrivel in animal cells) because the extremely salty water has a higher solute concentration, drawing water out of the cell.
