| Question | Answer |
|---|---|
| scientists have identified how many species, and how many species are left to be identified | 1.5 mil identified, 2-100 mil left to be identified |
| taxonomy | classification of organisms+ given universally accepted name (in Latin) |
| binomial nomenclature (and who invented it) | two-part name for classification, invented by Carolus Linneaus) |
| what are the levels of classification | kingdom, phylum, class, order, family, genus, species (remember kings play cards on five green stools) |
| phylogeny | study of evolutionary relationships between organisms |
| evolutionary classification | organizing groups based on evolutionary history (used because sometimes organisms that look similar don't have a common ancestor) |
| cladogram | like a tree diagram |
| derived characters | located in newer generations in cladogram but not in older generations |
| what is the domain, kingdom, cell type, cell structure, number of cells, mode of nutrition and examples of bacteria | bacteria, eubacteria, prokaryote, cell walls w/peptoglycan, unicellular, autotroph or heterotroph, strep, e. coli |
| what is the domain, kingdom, cell type, cell structure, number of cells, mode of nutrition and examples of archea | archea, archaebacteria, prokaryote, cell walls without peptoglycan, unicellular, autotroph or heterotroph, methanogens, halophiles |
| what is the domain, kingdom, cell type, cell structure, number of cells, mode of nutrition and examples of protists | eukarya, protista, cell walls of cellulose in some; some have chloroplasts, most unicellular and some multicellular, autotroph or heterotroph, ameoba |
| what is the domain, kingdom, cell type, cell structure, number of cells, mode of nutrition and examples of fungi | eukarya, fungi, eukaryote, cell walls of chitin, most multicelluar, some unicelluar, heterotroph, mushroom |
| what is the domain, kingdom, cell type, cell structure, number of cells, mode of nutrition and examples of plants | eukarya, cell walls of cellulose, chloroplasts, multicellular, autotroph, mosses, ferns trees |
| what is the domain, kingdom, cell type, cell structure, number of cells, mode of nutrition and examples of animals | eukarya, eukaryote, no cell walls or chloroplasts, multicellular, heterotroph, mammals |
| what are four important characteristics of a population | -geographic distribution -population -growth rate -age structure |
| what are three factors that affect population size | -number of births -number of deaths -number of individuals moving in/out of the population |
| natality | birth rate |
| logistical growth | s curve |
| exponential growth | j curve |
| what is rate strategy (also known as r strategy) | used in smaller animals with shorter lifespans and produces many offspring |
| what is carrying capacity strategy (also k-strategy | used in larger animals with longer lifespans and produces fewer offspring |
| dispersal | movement of organisms away from the parent organism |
| uniform dispersal | uniform |
| random dispersal | random |
| clumped dispersal | clumped |
| limiting factor | what causes the population to decrease and not continue to grow exponentially |
| what are 4 density dependent factors (depend on population size) | competition predation parasitism disease |
| when do density dependent factors happen | when a population reaches a certain level (affects large and dense populations more than small and sparse) |
| density independent factors (DONT depend on population size) | unusual weather natural disasters seasonal cycles certain human activities |
| when did the human population growth start to increase exponentially | 500 years ago during the 1st industrial revolution |
| demography | study of human populations |
| look at demographic transition graphs and age structure diagrams | did u? :) |
| population growth depends highly on what | age distribution |
| population | a group of animals that can interbreed |
| what is a grid that you put over a small population to count it called | quadrat |
| when a population increases by a constant factor at constant time intervals, it expiriences what type of growth? | logistical growth |
| what kind of population growth is characterized by a repeating cycle of rapid increase in size followed by rapid decline | boom and bust cycles |
| competition between members of the same species | intraspecific |
| competition between members of different species | interspecific |
| Hardy-Weinburg principle | states that two species cannot occupy the same niche indefinitely without competition driving one into extinction |
| look at the graph of demographic transition | did u do it? |
