QCE BiologyPractice Examination 5

This paper covers

• Cane toad invasion ecology — competitive exclusion, carrying capacity, population growth curves, species distribution
• Biodiversity measures — Simpson's Diversity Index, species richness, evenness, percentage cover
• Linnaean taxonomy, binomial nomenclature, cladistics and molecular phylogeny
• Ecological interactions — interspecific competition, predation, mutualism, parasitism, niche theory
• Energy flow and trophic levels — 10% rule, ecological pyramids
• Biogeochemical cycling — water, carbon, nitrogen
• Succession — primary, secondary, seral stages, climax communities
• DNA structure, semi-conservative replication, transcription and translation
• Meiosis and sources of genetic variation — crossing over, independent assortment, random fertilisation
• Epigenetics, gene regulation, transcription factors
• Mutations — gene and chromosomal
• Inheritance patterns — monohybrid, dihybrid, sex-linked, polygenic
• Biotechnology — PCR, gel electrophoresis, recombinant DNA
• Natural selection — directional, stabilising, disruptive
• Allele frequency, Hardy-Weinberg equilibrium, microevolution
• Speciation — allopatric, sympatric; divergent and convergent evolution, adaptive radiation, extinction
• Fossil, molecular and phylogenetic evidence for evolution
