1. Investigating yeast activity via CO\\(_2\\) production, effect of temperature on enzyme activity, and standardization techniques for experimental conditions.

2. Modification of experimental procedures to test pH influence on yeast enzyme activity, and identification of systematic errors in foam height measurements.

3. Glucose concentration effects on yeast respiration, graphical representation of CO\\(_2\\) production, and interpolation for unknown glucose concentrations.

4. Plan diagrams and cellular structure analysis of plant leaves, focusing on vascular bundle dimensions and xerophytic adaptations.

5. Microscopic comparison of plant leaf specimens, calibration of eyepiece graticules, and structural features aiding water conservation in arid environments.
