← ScienceWhich outcome occurs when exceeding the Reynolds number threshold within a microfluidic biochemical assay?
A)Turbulent mixing impairs reagent control✓
B)Laminar flow ensures precise layering
C)Systematic diffusion dominates reactions uniformly
D)Surface tension eliminates convective transport
💡 Explanation
Exceeding the Reynolds number induces turbulence, because inertial forces dominate viscous forces, creating chaotic flow via vortex shedding. Therefore, reagent control is impaired rather than preserved because laminar transport relies on orderly fluid motion instead.
