How many saw-toothed projections does the sawtooth grain beetle have on each side?

Explanation:
The trait being tested is a distinctive feature on the beetle’s pronotum: the lateral edges have saw-like teeth. For the sawtoothed grain beetle, there are six of these projections on each side. That consistent six-toothed pattern is what helps identify it and differentiate it from other stored-product beetles, making six the correct count. The other numbers don’t match the characteristic serration pattern seen in this species.
