Determine the concentration of the solution based on the predominant movement of water molecules through the cells

The first picture is hypersonic, because water is moving to the outside. This means the solution has much more salt than the cell does. The second photo is hypotonic, because water is entering the cell. This means the solution has the same amount as the cell. The last photo is isotonic, because water is moving both in and out of the cell. This means both the cell and the solution have equal amounts of salt.

I’m going to go with b!

In fact it is not just nuclear fusion and fission that  can  transform  matter  (or mass)into energy. any time  energy  is produced, some small amount of  matter  or mass isconverted into energy.
