1. Evolution and DNA Analysis: Use of PCR and gel electrophoresis to analyze Homo species DNA, determining genetic relationships between Homo longi and other species. 2. Biodiversity and Environmental Impact: Measuring biodiversity in different pond ecosystems, effects of pollutants on species diversity, and calculation of the index of diversity. 3. Genetics and Cell Division: Structure and replication of DNA, semi-conservative replication, mitosis observation in plant tissues, and role of chromosomal organization. 4. Seed Banks and Medicinal Plants: Conservation of endangered species through seed banking, drug development from plants, and phases of clinical trials for new medicines. 5. Respiratory Adaptations and Evolution: Myoglobin function in diving shrews, natural selection leading to physiological changes, and gene mutations affecting protein structure. 6. Antibiotic Resistance and Infection Control: Mechanisms of bacterial resistance, effectiveness of bactericidal vs. bacteriostatic antibiotics, and strategies to prevent antibiotic-resistant infections.
