The making of a hypothesis to explain the observation related to the shark and rays feeding behaviour, as despite of their predatory feeding habit, largest species feed on plankton. Introduction: The largest fishes present in the ocean depends on sea’s smallest organisms for their food. It includes a number of massive plankton-feeding elasmobranchs. Elasmobranchs is a group of fishes that includes rays and sharks. These fish species are evolved the adaptations to gulp a huge amount of water followed by filtering of plankton, shrimp and small fishes. These filter- feeding species evolved their particular diet and feeding morphology independent to each other.

You’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.
