← Nature & AnimalsWhen dinoflagellates in a turbulent ocean encounter an object, which effect upon encountering causes widespread signaling?
A)Quorum sensing induces a luciferin cascade
B)Shear stress triggers mechanotransduction in vacuoles✓
C)Osmotic shock amplifies autofluorescent protein release
D)Eutrophication boosts algae energy production
💡 Explanation
Shear stress triggers mechanotransduction because it induces bioluminescence at contact via mechanically-gated ion channels in the vacuole; therefore a propagating wave of light rather than merely localized emission is produced, unlike quorum sensing.
