It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up about 70–90% of eucalyptus oil. Eucalyptol forms crystalline adducts with hydrohalic... |
https://en.wikipedia.org/wiki/Kuramoto%20model | The Kuramoto model (or Kuramoto–Daido model), first proposed by , is a mathematical model used in describing synchronization. More specifically, it is a model for the behavior of a large set of coupled oscillators. Its formulation was motivated by the behavior of systems of chemical and biological oscillators, and it h... |
https://en.wikipedia.org/wiki/Functional%20group%20%28ecology%29 | A functional group is merely a set of species, or collection of organisms, that share alike characteristics within a community. Ideally, the lifeforms would perform equivalent tasks based on domain forces, rather than a common ancestor or evolutionary relationship. This could potentially lead to analogous structures t... |

It is a highly toxic emerald-green crystalline powder that has been used as a rodenticide and insecticide, and also as a pigmen... |
https://en.wikipedia.org/wiki/Plesiomorphy%20and%20symplesiomorphy | In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades.
Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy, all mean a trait shared between species because they share an... |

https://en.wikipedia.org/wiki/Rejuvenation | Rejuvenation is a medical discipline focused on the practical reversal of the aging process.
Rejuvenation is distinct from life extension. Life extension strategies often study the causes of aging and try to oppose those causes in order to slow aging. Rejuvenation is the reversal of aging and thus requires a different... |
https://en.wikipedia.org/wiki/Ball%20detent | A ball detent is a simple mechanical arrangement used to hold a moving part in a temporarily fixed position relative to another part. Usually the moving parts slide with respect to each other, or one part rotates within the other.
The ball is a single, usually metal sphere, sliding within a bored cylinder, against the... |
