Symbiogenesis, or endosymbiotic theory, is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes.It states that several key organelles of eukaryotes originated as a symbiosis between separate single-celled organisms.olecular and biochemical evidence suggest that mitochondria developed from proteobacteria (in particular, Rickettsiales, the SAR11 clade, or close relatives) and chloroplasts from cyanobacteria (in particular, nitrogen-fixing filamentous cyanobacteria).
Standard ratios are:Tinctures of dried, intense botanicals are 1:10. This means 1 part herb, an ounce for instance, to 10 parts liquid, also measured in ounces. Examples of this type of herb are cayenne and the resins such as myrrh and propolis.
The difference between extracts and tinctures is the amount of herb infused in the alcohol or glycerin. An extract is considered 1 part herb to 1 part alcohol or glycerin. A tincture is considered 1 part herbs to 3 parts alcohol or glycerin.
