Suppose you are conducting a study to compare firefly populations exposed to normal daylight/darkness conditions with firefly populations exposed to continuous light (24 hours a day). you set up two firefly colonies in a laboratory environment. the two colonies are identical except that one colony is exposed to normal daylight/darkness conditions and the other is exposed to continuous light. each colony is populated with the same number of mature fireflies. after 72 hours, you count the number of living fireflies in each colony.
