We study behavioral adaptation, the change in behavior as a result of a change in the environment. Other research at successively more molecular levels could investigate cellular adaptation, atomic adaptation, or even the adaptation of existence itself. A more molar question could involve how proportions of a population come to participate as the result of some independent variable.
Obviously every research question need not go unanswered until we understand the ultimate nature of existence itself.
In summary, the difference between biology, psychology and sociology is an interest in: changes in cells, changes in the behavior of individuals, and changes in the proportions of a population reacting to an event.
