1. Investigating starch hydrolysis by α-, β-, and γ-amylases using chromatography and enzyme-specific optimal conditions.
2. Controlled experimental design for analyzing enzyme activity, including appropriate variables and control setup.
3. Chromatographic methods for comparing enzymatic hydrolysis products over time, with identification of amylase types based on product patterns.
4. Bt maize efficacy in rootworm control compared to non-Bt maize with insecticides, assessed through random plot experiments and rootworm counts.
5. Statistical hypothesis testing to compare Bt maize, non-Bt maize, and insecticide treatments for pest control.
6. Interpretation of statistical significance in pest control effectiveness, particularly results not significant at \\( p < 0.05 \\).
