Content
Year 11
- BI-11-03
analyses the relationships between organisms and their environment using the theory of evolution by natural selection
Relevant Working scientifically outcomes and content must be integrated with each focus area. All the Working scientifically outcomes and content must be addressed by the end of Year 12.
LoadingDiscuss the role of Loading , inheritance and selective pressures in contributing to the process of evolution by Loading
Use examples to demonstrate how Loading and Loading factors exert selective pressures on populations
Explain how human-induced changes may function as selective pressures
Analyse how evolution causes species diversity
Describe examples from Aboriginal palaeontological evidence that demonstrate the existence of Australian megafauna
Evaluate the role of isolation and adaptation in the evolution of Australian monotremes and marsupials
Conduct a practical investigation to model the processes involved in natural selection
Discuss the Loading of various Loading that demonstrate natural selection
Use examples to explain convergent and divergent evolution
Use plant and animal examples to explain how structural, physiological and behavioural adaptations shaped by evolution enable survival in their environment
Conduct a practical investigation to examine structural adaptations for water balance in Australian plants
Use examples to explain behavioural adaptations used by Loading and Loading to survive in the Australian environment
Analyse data to compare how the external environment and body temperature are related in endotherms and ectotherms
Explain physiological adaptations of aquatic animals to regulate water and salt balance
Explain how Loading use the adaptations of local plants and animals for specific purposes
Use Loading to compare the Loading model with the Loading model of evolution
Conduct a secondary-source investigation to analyse how human-induced pressures can drive the emergence of antibiotic-resistant strains of bacteria and Dichloro-Diphenyl-Trichloroethane (DDT)-resistant mosquitoes
Analyse information on how transitional Loading , fossil assemblages and relative dating have provided palaeontological and geological evidence for past changes in life forms
Conduct a Loading to infer evolutionary relationships between species using Loading and Loading sequences
Evaluate Loading , genetic phylogeny, biogeography and biochemistry as evidence for the theory of evolution by natural selection
Conduct a practical investigation to collect and analyse abiotic and biotic data, to discuss the features of an Loading
Compare abiotic data from a variety of aquatic and terrestrial ecosystems
Explain how abiotic and biotic factors influence the abundance, distribution and diversity of species in an ecosystem
Compare sampling techniques to estimate distribution and abundance of organisms
Conduct a practical investigation to examine the distribution and abundance of a plant or animal using belt Loading , line transect or Loading sampling techniques
Conduct a practical investigation to model the mark-release-recapture method and estimate abundance of mobile organisms
Use examples to determine relationships between organisms, including Loading , competition, Loading , Loading , Loading and Loading
Analyse data on the impact of predator–prey relationships and competition on populations
Explain how the Loading of a selected ecosystem is affected by biotic and abiotic factors
Evaluate the validity, Loading and Loading of ecological sampling data when drawing conclusions about ecosystem dynamics
