The endosymbiotic theory concerns the origins of mitochondria and chloroplasts, which are organelles of eukaryotic cells. According to this theory, these originated as prokaryotic endosymbionts, which came to live inside eukaryotic cells.he theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).
The rational root theorem is a special case (for a single linear factor) of Gauss's lemma on the factorization of polynomials. The integral root theorem is a special case of the rational root theorem if the leading coefficient a n = 1.
Rational Functions. A rational function is defined as the quotient of polynomials in which the denominator has a degree of at least 1. In other words, there must be a variable in the denominator. Examples: The parent function of a rational function is and the graph is a hyperbola.The domain and range is the set of all real numbers except 0. Excluded value. In a rational function, an excluded value is any x-value that makes the function value y undefined.ational Functions.
