Classification 0.0 / 5 ? BiologyDNA, genetics and evolutionHuman, animal and plant physiologyHuman, animal and plant behaviourASAQA Created by: Betsy_2018Created on: 14-02-17 16:37 What is evolution? Change in allele frequency of a population over generations 1 of 16 What causes genetic diversity? Independent segregation, mutation, crossing over 2 of 16 What forms the first and second part of a binomial name? (1) The genus and (2) the species names 3 of 16 Why are binomial systems in a constant state of change? To keep up with scientific discoveries based on evolution, physiology, biochemistry and behaviour 4 of 16 What are the two types of classification (taxonomy)? Artificial (analogous characteristics) and phylogenetic (origins) 5 of 16 How is the phylogenetic classification (phylogeny) represented visually? In a phylogenetic tree; the branches closer together have close common ancestors 6 of 16 What are the 3 domains? Bacteria, Eukarya, Archaea 7 of 16 What are archaea? Single celled prokaryotes that have similar genes to eukaryotes; fatty acid-glycerol membranes (ether bonds) 8 of 16 What are the 4 kingdoms of Eukarya? Protoctista, Fungi, Plantae, Anamalia 9 of 16 What is the highest phylogenetic taxon? Domain 10 of 16 What is the 3rd taxon of the hierarchy (not including Domain)? Class 11 of 16 What is the 5th taxon of the hierarchy (not including Domain)? Families 12 of 16 What is the total phylogenetic classification order? Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species 13 of 16 How many species have been identified? 1.8 million 14 of 16 What is the estimated number of total species that have lived on Earth? 14 million 15 of 16 What is a diversity index? A number that assessed the species richness and evenness 16 of 16
