The equipment that the arson investigator used is ultraviolet
fluorescence. The mechanism in this Ultraviolet Fluorescence in which UV
radiation excites chemicals in object and causes them to release visible light.
Arson investigator is a part detective and part fire scientist.

Answer:
Neural crest cell movements are inhibited.
Explanation:
Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.
Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.
Thus, the answer is neural crest cell movements are inhibited.
