Study the stages of mitosis and its role in growth, repair, and asexual reproduction, ensuring genetic continuity.

Examine the stages of Meiosis I, highlighting homologous chromosome separation and crossing over as sources of variation.

Detail the stages of Meiosis II, focusing on sister chromatid separation and the formation of haploid gametes.

Interpret karyotypes to identify chromosomal number and structural abnormalities, linking them to genetic disorders.

Apply Mendel's laws of segregation and dominance to predict inheritance patterns in monohybrid crosses.

Extend Mendelian principles to dihybrid crosses, applying the law of independent assortment to predict two-trait inheritance.

Investigate inheritance patterns that deviate from simple Mendelian ratios, such as incomplete dominance and codominance.

Explore complex inheritance patterns including multiple alleles (e.g., blood types) and polygenic inheritance (e.g., skin color).

Study the inheritance of genes located on sex chromosomes, focusing on X-linked traits and their unique patterns, and interpret pedigrees.

Classify different types of point mutations (substitution, insertion, deletion) and their effects on protein synthesis.

Investigate large-scale chromosomal abnormalities, including deletions, duplications, inversions, and translocations.

Examine natural and induced causes of mutations, including spontaneous errors and environmental mutagens.

Explore how mutations are the ultimate source of new alleles and genetic variation, driving evolutionary change.

Understand the principles and techniques of recombinant DNA, including restriction enzymes, plasmids, and gene cloning.

Learn the applications of Polymerase Chain Reaction (PCR) for DNA amplification in various contexts.

Understand the principles of gel electrophoresis for DNA separation and its application in DNA profiling (e.g., STR analysis).

Explore the mechanisms and ethical implications of CRISPR-Cas9 technology for precise gene editing.

Examine the uses of biotechnology in developing new medicines, gene therapies, and vaccines.

Investigate the applications of biotechnology in agriculture, focusing on genetically modified organisms (GMOs) and their impact.

Apply the Hardy-Weinberg principle to calculate allele and genotype frequencies in non-evolving populations.

Investigate how gene flow and genetic drift alter allele frequencies and genetic diversity in populations.

Explore the principles of natural selection, including variation, inheritance, selection, and differential survival.

Apply population genetics principles to conservation efforts, focusing on maintaining genetic diversity in endangered species.

Categorize different types of pathogens (viruses, bacteria, fungi) and their basic characteristics and life cycles.

Investigate the characteristics and disease mechanisms of protist pathogens and prions.

Investigate direct and indirect methods of pathogen transmission, including vectors and environmental reservoirs.

Explore epidemiological concepts like incidence, prevalence, and outbreak patterns (epidemic, pandemic, endemic).

Discuss factors contributing to the emergence and re-emergence of infectious diseases globally.

Study the physical, chemical, and biological barriers that form the body's non-specific innate immune response.

Examine the cellular components of innate immunity, including phagocytes, natural killer cells, and the inflammatory response.

Introduce the specific, memory-based adaptive immune system, distinguishing between humoral and cell-mediated responses.

Detail the role of B lymphocytes in producing antibodies and the process of clonal selection.

Examine the functions of T lymphocytes (helper T cells, cytotoxic T cells) in targeting infected cells and coordinating immune responses.

Explore common immune system dysfunctions, including allergies and autoimmune diseases.

Investigate primary and acquired immunodeficiencies and their impact on the body's ability to fight infection.

Understand how vaccines stimulate active immunity and the concept of herd immunity in protecting populations.

Investigate the mechanisms of action of antiviral drugs and antibiotics, and the challenge of antimicrobial resistance.

Evaluate public health strategies for disease prevention and control, including sanitation, quarantine, and education.

Define homeostasis and its importance for organism survival, introducing the concept of feedback loops.

Investigate how organisms maintain a stable body temperature through physiological and behavioral adaptations.

Study the hormonal control of blood glucose levels by insulin and glucagon, and the role of the pancreas.

Examine how the kidneys and other organs maintain water and salt balance in the body.
