  Probabilities of various Fock states with strange and nonstrange quark-gluon
sea contents are calculated to probe the hadronic structure. Particularly for
nucleon, we find various contributions to the low energy properties from
scalar, vector and tensor sea in addition to three valence quarks. We focus on
the importance of individual sea contributions to the low energy parameters of
nucleon by taking the strange and non strange quark-gluon content to the hadron
sea. We confirm that the extended Fock space wavefunction is capable of
explaining the experimental results where vector sea plays a crucial role in
studying hadronic structure while scalar and tensor sea appears to be less
dominating due to quark-spin flip process but cannot be neglected. Some of the
properties like spin distribution and gA/gV ratio seem to be the most affected
by the change in the statistically determined coefficients. Detailed analysis
includes different approximations within the statistical approach to test the
validity of the model chosen. Phenomenological implication of such sea
affecting these properties is also discussed and the results are compared with
the experiments.
