Low blood-glucose levels: hypoglycemia: can cause confusion, unconsciousness, and seizures.

Peak concentration occurs 2-4 hours after injection. Scientific method: process involving the formulation of questions and conjectures arising from observations, careful design of experiments, and thoughtful analysis of results. Involves identifying ways to test the validity of new ideas: seldom is there one way to go about it.
