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.
Rates. A ratio is a comparison of two numbers or measurements. The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69, the rate is 69 for 12 ounces.The first term of the ratio is measured in cents; the second term in ounces. You can write this rate as 69 /12 ounces or 69 :12 ounces.he numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69, the rate is 69 for 12 ounces.
