1. Phototropism and Auxins: Investigating oat coleoptile curvature towards light, effect of shading on growth direction, and role of IAA in elongation.
2. Influenza Virus and Immunology: Why antibiotics are ineffective against viruses, spike protein mutations, and methods to compare different viral strains.
3. Ecosystem Succession and Carbon Storage: Graph analysis of biomass and productivity over time, effects of plant succession on atmospheric CO₂ levels.
4. Antimicrobial Properties of Lantana Leaves: Comparing extraction solvents for antibacterial efficacy, inhibition zones for Gram-positive and Gram-negative bacteria.
5. Neuroscience and Habituation: Effect of synapsin protein reduction on fruit fly learning response, measuring jump response, and synaptic vesicle inhibition.
6. Metabolism and Storage Molecules: Conversion of starch to glycogen in red flour beetle eggs, glucose metabolism during embryonic development, and respirometer use to detect aerobic respiration.
