When they ntruding termites and are substance A single drop of the liquid extracted from blue termites was placed on individuals of a second termite species, Labiotermes labraltis, and the number that were immobilized (dead or paralyzed) within 60 minutes was recorded. crystals was dropped instead The frequency of this outcome was compared with a control treatment in which liquid from glands of 'white" termites lacking teh blue Liquid Source Unharmed | Immobilized Blue Workers White Workers31 37 What is the expected number of unharmed blue workers? What is the expected number of immobilized blue workers? What is the expected number of unharmed white workers? What is the expected number of immobilized white workers?
