I can describe the classification, and sometimes reclassification, of organisms based on evidence from their gene sequences.
I can describe the classification of organisms based on evidence from their phenotype and cells.
I can describe the size and scale of cells and cell structures, and explain how electron microscopy has increased our understanding of sub-cellular structures.
I can describe the common features of the cells of eukaryotic and prokaryotic organisms.
I can describe examples of mutations in bacteria and explain why advantageous genetic variants became more common in the bacterial population.
I can explain how natural selection leads to advantageous genetic variants becoming more common over generations.
I can describe how mutations change the DNA sequence in the genome causing genetic variation, which can cause heritable variation in phenotype.
I can explain the properties, uses and dangers of non–ionising electromagnetic radiation.
I can explain the properties, uses and dangers of ionising electromagnetic radiation.
I can describe how to investigate the emission of infrared radiation by different surfaces.
