• Cells (Tissues, organs, systems, structures and function; factors affecting human health; physiology; vaccination) 

• Organisms ( habitat, ecosystems, interdependency, unity and diversity in life forms; energy transfer and cycles [including nutrient, carbon, nitrogen]; classification) 

• Processes (photosynthesis, cell respiration, aerobic and anaerobic; word and chemical equations)

• Metabolism (nutrition, digestion, biochemistry and enzymes; movement and transport, diffusion; osmosis; gas exchange, circulation, transpiration and translocation; homeostasis) 

• Evolution (life cycles, natural selection; cell division, mitosis, meiosis; reproduction; biodiversity; inheritance and variation, DNA and genetics) 

• Interactions with environments (tropisms, senses, nervous system, receptors and hormones) 

• Human interactions with environment (human influences, habitat change or destruction, pollution/conservation; over-exploitation, mitigation of adverse affects) 

• Biotechnology (genetic modification, cloning; ethical implications, genome mapping and application, 3D tissue and organ printing)
