LIGHT / TO CONSTRUCT USEING Food making process by which plants and other producers use light energy to produce glucose and oxygen from carbon-dioxide and water (6) CO2 + (6) H2O = C6H1206 + (6) O2 |

Definition
(EARTH SCIENCE) When molecules of one substance(usually a solute) are spread evenly throughout another substance(usually a solvent) ... Example a Solution of Salt dissolved in Water
(BIOLOGY) ALSO because all matter that can flow is in a constant state of movement. When a material (example water) flows across/thru a cell membrane equally in both directions so there is no gain in the number of water molecules on either side of the cell membrane. |
