The range of abiotic and biotic conditions under which a species persists is its realized niche. 

The realized niche determines the geographic range of a species or of various populations that compose a species.

In the presence of brassinolide, the activated phosphatase BSU1 dephosphorylates BIN2 and promotes its degradation by the 26S proteasome system, thus blocking its activity. BES1 and BZR1

are then dephosphorylated by PROTEIN PHOSPHATASE2A

(PP2A), and the active forms of BES1 and BZR1 move into the nucleus where they regulate the expression of brassinolide response genes

If the frictional force taken into the consideration (which depend on hydrodynamic size, shape of the molecule, pore size of the medium, & pore size of the medium) velocity, v , of a charged molecule in an electric field is therefore given by the equation

where f is the frictional coefficient.
