STEM QUIZ

1. Diversity in the Living World

• Biodiversity: Patterns, importance, and levels (Genetic, Species, Ecosystem).
• Conservation: Threats (habitat loss, overexploitation) and strategies (In-situ vs. Ex-situ).
• Taxonomy: Classification hierarchy and categories.

2. Ecosystem

• Structure & Function: Productivity, decomposition, energy flow, and nutrient cycling.
• Dynamics: Ecological pyramids (Biomass, Energy, Numbers), food chains/webs, and ecological succession.

3. Reproduction

• Human Reproduction: Anatomy, gametogenesis, menstrual cycle, fertilization, and pregnancy.
• Reproductive Health: Contraceptive methods, STIs, and assisted reproductive technologies (IVF, ZIFT, GIFT).
• Flowering Plants: Flower structure, pollination, double fertilization, and seed/fruit development.

4. Genetics and Evolution

• Inheritance: Mendel’s laws, chromosomal theory, sex determination, and genetic disorders (e.g., Down syndrome, hemophilia).
• Molecular Biology: DNA/RNA structure, replication, transcription, translation, and gene regulation.
• Evolution: Origin of life, Darwinism, evidence (fossils, anatomy), and mechanisms (natural selection, Hardy-Weinberg).

5. Biotechnology

• Principles: Recombinant DNA technology, restriction enzymes, vectors, and PCR.
• Applications: Genetically modified crops (Bt cotton, Golden rice), human insulin production, gene therapy, and biopiracy/ethics.

6. Biology and Human Welfare

• Health & Disease: Pathogens, immune system function (vaccines, immunity types), and major diseases (AIDS, cancer).
• Microbes: Applications in household products, industry (antibiotics), sewage treatment, and biofertilizers.

7. Organisms and Populations

• Demographics: Birth/death rates, sex ratio, and population growth models.
• Interactions: Predation, competition, parasitism, mutualism, and environmental adaptations.
