NCEA Level 3 Biology study guide
NCEA Level 3 Biology · Work through your exam, one topic at a time.
NCEA Level 3 Biology is the final year of the Biology subject pathway in New Zealand's National Certificate of Educational Achievement, described by NZQA as "the scientific study of living things, and the interconnectedness of life forms and the environment." It is designed for Year 13 learners who want a deeper, more analytical treatment of biology and a foundation for tertiary study in the biological and health sciences. Level 3 Biology is assessed through a mix of internal and external assessment. The NCEA Level 3 Biology study guide has 7 sections and about 2,024 words.
01Carry out a practical investigation in a biological context, with guidance
This domain assesses how you plan, carry out, process and evaluate a practical biological investigation, with guidance. The exam looks for valid variables, reliable sampling, accurate measurement, and reasoned evaluation rather than a perfect result.
309 words, about 2 min02Integrate biological knowledge to develop an informed response to a socio-scientific issue
This domain assesses your ability to integrate biological knowledge into an informed response to a socio-scientific issue. A socio-scientific issue has a biological component and social, ethical, economic or political dimensions.
297 words, about 1 min03Demonstrate understanding of the responses of plants and animals to their external environment
This domain assesses how plants and animals respond to external stimuli. You need to explain receptors, effectors and responses, and compare plant tropisms and nastic responses with animal taxes, kinesis, migration and biological rhythms.
299 words, about 1 min04Demonstrate understanding of how an animal maintains a stable internal environment
This domain assesses how an animal maintains a stable internal environment despite external change. You need to explain negative feedback, receptors, control centres, effectors, and specific mechanisms such as thermoregulation, osmoregulation and blood glucose regulation.
273 words, about 1 min05Demonstrate understanding of evolutionary processes leading to speciation
This domain assesses evolutionary processes that lead to speciation. You need to explain variation, selection, gene flow, genetic drift, reproductive isolation, and the difference between allopatric and sympatric speciation.
267 words, about 1 min06Demonstrate understanding of trends in human evolution
This domain assesses trends in human evolution. You need to interpret anatomical evidence for bipedalism, encephalisation, reduced dentition and tool use, and explain the relationships among hominin species.
291 words, about 1 min07Demonstrate understanding of human manipulations of genetic transfer and its biological implications
This domain assesses human manipulations of genetic transfer and their biological implications. You need to explain techniques such as selective breeding, cloning, transgenesis and gene editing, and evaluate biological, ethical, legal and economic consequences.
