When the concentration of solute inside and outside a cell is the same, the cell has reached?

           When the concentration of solute inside and outside a cell is the same, the cell has reached isotonic condition".

Explanation:

                   In isotonic condition the osmolarity of solute in and outside cell is same, therefore no net flow of water occurs. Semipermeable membrane ha a key role in maintaining isotonic condition in and outside the cell because this membrane allow the movement of water but prevent the entry of other molecules. 

Characteristic expected of mineral from lava at earth's surface

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
