| 1 | Manufacturing the screws out of the hydroxyapatite composite also simplifies production. | |
| 2 | The biopolymer polyhydroxyalkanoate came next on the list. | |
| 3 | That finding is reinforced by a second set of lines, in the ultraviolet part of the spectrum, which indicate the presence in the plume of hydroxyl radicals. | |
| 4 | As open-chain hydroxy aldehydes and hydroxyl ketenes, the monosaccharides are very reactive. | |
| 5 | Eventually, atmospheric methane reacts with hydroxil ions to form CO2 and water. |
