1. Antibiotic diffusion experiment using agar blocks as a model for bacterial inhibition, serial dilution preparation, and end-point observation.

2. Measurement and estimation of unknown antibiotic concentrations based on diffusion results, with error identification and control.

3. Investigation of the effect of temperature on diffusion rates by modifying antibiotic concentration as a standardized variable.

4. Glucose uptake in animal cells analyzed by plotting concentration vs. uptake rate to support facilitated diffusion.

5. Detailed structural analysis of plant vascular tissues, including phloem and xylem cell organization, and calculation of midrib to vascular bundle depth ratio.

6. Identification of aquatic adaptations in leaf cross-sections and comparison of midrib structures between different plant species.
