- 4. a substance, typically a liquid, that dissolves a solute to create a solution
- 5. a chemical compound containing a phosphorus atom bonded to four oxygen atoms
- 6. a chemical reaction where two molecules combine to form a larger one, with the removal of a small molecule like water
- 8. compounds of nitrogen and oxygen that are essential for plant and animal life, playing a key role in the nitrogen cycle as they are found naturally in soil, water, and some foods
- 11. the attraction between molecules of the same substance, which causes them to stick together

Down
- 2. 0°C (32°F)
- 3. uneven distribution of charge within a molecule, creating a positive and negative end, or to the persistent asymmetry of structures along an axis in a cell or organism
- 7. the land area where all the water—from rain, snowmelt, and other runoff—drains into a common body of water, such as a river, lake, or bay, affecting the habitat and organisms within it.
- 9. dissimilar molecules, cells, or substances sticking to each other due to attractive forces at their surfaces.
