The theory was originally developed as island biogeography, to explain species richness of actual islands, principally oceanic. It proposes that the number of species found in an undisturbed insular environment is determined by immigration and extinction.
Explanation:
Wilson of Harvard, developed a theory of "island biogeography" to describe such uneven distributions. They suggested that the number of species on any island displays a balance within the rate at which new species establish it and the rate at which residents of secured species become extinct.

The selenium particles when coated on paper towels were extremely effective and continuously inhibited (about a 90% reduction) the growth of gram-positive bacteria including S. aureus and S. epidermidis after 24, 48, or 72 hours.
the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
The gas particles occupy the entire container that contains them, colliding with the walls of the same, the degree of separation between the particles is large. The gases have no defined shape or volume, are highly compressible
Purines: Heterocyclic rings are synthesized one atom at a time, first atom attached to ribose phosphate (source is PRPP) and then all the other atoms are added .
Pyrimidines: Common intermediate, orotate, synthesized first, then orotate is attached to ribose phosphate (source is PRPP or 5-Phosphoribosyl-1-pyrophosphate).
