3. Reproductive Health
   This chapter addresses reproductive health issues, strategies for population stabilization, birth control methods, and sexually transmitted diseases. It also discusses infertility, medical termination of pregnancy, and health education.

4. Principles of Inheritance and Variation
   Covers Mendel’s laws of inheritance, including dominance, segregation, and independent assortment. It also explores genetic variations, polygenic inheritance, pleiotropy, mutations, genetic disorders, and chromosomal abnormalities.

5. Molecular Basis of Inheritance
   Focuses on DNA as the genetic material, covering replication, transcription, translation, and gene expression regulation. Topics like the Human Genome Project and DNA fingerprinting are also discussed.

6. Evolution
   This chapter examines the origin of life, the theory of evolution, and mechanisms driving evolutionary processes. It also covers evidence for evolution, adaptive radiation, and the evolution of humans.

7. Human Health and Disease
   Explores various human diseases caused by bacteria, viruses, fungi, protozoa, and worms. It also covers immunity, vaccination, AIDS, cancer, and the effects of drugs and alcohol on health.

8. Microbes in Human Welfare
   This chapter discusses the positive roles of microbes in human welfare, such as in sewage treatment, biogas production, as biofertilizers, and biocontrol agents. It also highlights their use in industrial and household products.

9. Biotechnology: Principles and Processes
   Introduces biotechnology, genetic engineering, and recombinant DNA technology. It discusses tools like restriction enzymes, cloning vectors, PCR, and gene transformation processes used to create genetically modified organisms.

10. Biotechnology and its Applications
    Focuses on the application of biotechnology in agriculture and medicine, including genetically engineered insulin, gene therapy, and molecular diagnostics. Ethical issues related to biotechnology are also explored.

11. Organisms and Population
    This chapter examines the structure and functioning of populations, including population growth, life history variations, and interactions among species within an ecosystem.

12. Ecosystem
    Discusses the structure and functions of ecosystems, including energy flow, productivity, decomposition, and ecological pyramids. It emphasizes the interdependence of organisms within ecosystems.

13. Biodiversity and Conservation
    Explores patterns of biodiversity, the loss of biodiversity, and strategies for conservation. This chapter emphasizes the importance of maintaining biodiversity for ecological balance and human welfare.
