Biology Stage 6 Syllabus
6 Course StructureThe Biology Stage 6 Syllabus has a Preliminary course and an HSC course. The Preliminary and HSCcourses are organised into a number of modules. The Preliminary modules consist of core content thatwould be covered in 120 indicative hours.
The HSC course consists of core and options organised into a number of modules. The core contentcovers 0 indicative hours with !"# option covering $0 indicative hours. Students are re%uired tocover !"# of the options.
Practical e&periences are an essential component of both the Preliminary and HSC courses. Studentswill complete '0 indicative hours of practical(field wor) during both the Preliminary and HSC courseswith no less than $* indicative hours of practical e&periences in the HSC course. Practical e&periencesmust include at least one open+ended investigation integrating s)ill and )nowledge outcomes in boththe Preliminary and HSC courses.
Practical e&periences should emphasise hands+on activities, including-

9.2 Maintaining a Balance
Conte&tual Outline
ulticellular organisms have specialised organ systems that are adapted for the upta)e and transportof essential nutrients from the environment, the utilisation or production of energy and the removal ofwaste products arising from cellular activities.
The basis of healthy body+functioning in all organisms is the health of their cells. The physical andchemical factors of the environment surrounding these cells must remain within narrow limits for cellsto survive. These narrow limits need to be maintained and any deviation from these limits must be%uic)ly corrected. = brea)down in the maintenance of this balance causes problems for the organism.
The nervous and endocrine systems in animals and the hormone system in plants bring about thecoordinated functioning of these organ systems. They are able to monitor and provide the feedbac)necessary to maintain a constant internal environment. #n;yme action is a prime e&le of the needfor this balance. #n;ymes control all of the chemical reactions that constitute the body:s metabolism.=s en;ymes normally function only within a narrow temperature range, even a small rise in bodytemperature can result in the failure of many of the reactions of metabolism that are essential to life.
This module increases students: understanding of the applications and uses of biology, implicationsfor society and the environment and current issues, research and developments in biology.

9.3 Blueprint of LifeConte&tual Outline
ecause all living things have a finite life span, the survival of each species depends on the ability ofindividual organisms to reproduce. The continuity of life is assured when the chemical information
that defines it is passed on from one generation to the ne&t on the chromosomes.odern molecular biology is providing opportunities to alter the information transferred from one
generation to the ne&t in technologies such as cloning and in the production of transgenic species.
The segregation and independent assortment of the genetic information within a species provides thevariation necessary to produce some individuals with characteristics that better suit them to survivingand reproducing in their environment. Changes in the environment may act on these variations. Theidentification of mutations and their causes becomes important in preventing mutations and inidentifying and potentially nullifying the effects of mutations in living organisms.
This module increases students: understanding of the history, nature and practice of biology, the
applications and uses of biology, the implications of biology for society and the environment andcurrent issues, research and developments in biology.

Conte&tual Outline
Bhen physiological processes malfunction, the body tries to repair the damage. The process is similarin all living things and it is only when the process fails to contain the damage that disease can berecognised.
Humans have long recognised the symptoms of disease both in themselves and the animals and plantsaround them. Since the beginnings of recorded history, they have noted the signs that reveal that the
body is malfunctioning. /ncreasing understanding of the causes of disease together with accompanyingadvances in technology have changed approaches to treatment and management of disease.
The search for measures to treat and manage diseases of humans and other organisms continues andthis search is paralleled by continued refinements in technology.
This module increases students: understanding of the history, nature and practice of biology, theapplications and uses of biology, and the implications of biology for society and the environment.

9.# $ption % Co&&unication
Conte&tual Outline
Humans are social animals and, as such, are in constant communication with others. any animalshave an e&tensive range of communication strategies that include both visual and vocal signals.4earning these signals relies heavily on the involvement of all the sensory organs as well as the brain.
Bhile the full range of senses can be involved in communication, the relative importance of each ofthe senses differs from animal to animal. This module focuses on the two senses that are important formany vertebrate and invertebrate animals A sight and hearing.
Human cultural development e&ploded with the development of speech and the concurrent increasingcomple&ity of communication. Dor some people, however, communication signals are not identifiedeffectively because of faults in the sending, receiving or deciphering of some of the signals. Bithincreasing advances in technology, assistance for people with difficulties in communicating continuesto improve.
This module increases students: understanding of the history, applications and uses of biology, theimplications of biology for society and the environment, and current issues, research anddevelopments in biology.

Science has come a long way since endel:s important wor) on identifying the transmission ofinherited factors across generations. The code for transmitting this genetic information has beenidentified and models have been developed to e&plain gene functioning. Transcription of theinformation into functional proteins is now well understood and models are being developed to testhow genes direct the structure, function and development of an organism.
odern genetics is moving towards an increased understanding of the biochemical role of individualgenes. This is being enhanced by the Human 5enome Pro8ect that has se%uenced the entire humangenome to identify all the encoded genes.

/t has been difficult for the biologist to fully understand cell function in particular, becausemicroanalysis of living tissue has never been easy. Bhen biologists have technologies at their disposalto watch intact structures operating, the complete story will be told.
