Live Interction

What will be the phenotypic ratio in a situation of complementary gene interction?

A segment of a charged wire of length l, charge density lambda_(2) and an infinitely long chaged wire. Charge density lambda_(1) . Lie in a plate at right angles to each other. The sepatation between the wires is r_(0) . Determine the force of interction between the wires.

The interaction of living organisms with the non-living environment constitutes the ecosystem.

Name the connecting link between living and non-living.
