It depends on the case, but usually two variables should be in a controlled experiment.
The binomial nomenclature system of classifying organisms was developed by <u>Linnaeus</u>.
Binomial nomenclature- Binomial nomenclature is a method of naming biological entities that consists of two terms: the first one designates the genus of the organism, and the second one designates the species.
Genus- Genus is the biological categorization that comes after family & species, consisting of isolated species that demonstrate exceptional differentiation or a group of structurally and phylogenetically related species (monotypic genus).
Species- A species is a group of organisms made up of similar individuals that are potential of interbreeding or gene exchange. The most fundamental unit of classification in biology is the species, which also serves as a taxonomic rank.

hello there,
Which equation represents the formula for the speed of a wave?
A.
speed = wave length ÷ wave period
hope this help
The right answer is photosystem I
And the three protein complexes are : plastoquinone, cytochrome b6f complex, plastocyanin.
In plants, photophosphorylation occurs in the membrane of thylakoids, within chloroplasts:
H2O ==> photosystem II (which contains P680) ==> plastoquinone ==> cytochrome b6f complex ==> plastocyanin → photosystem I (which contains P700) ==> ferredoxin ==> ferredoxin-NADP + reductase ==> NADP +
