---|---|---|---|---|---|
7 characteristics of life | made of cells, ordered complexity, respond to external stimuli, adapted to their environment, use energy, grow and reproduce, maintain homeostasis
🗑
|
||||
5 causes of evolutionary change | natural selection, non-random mating, gene flow, genetic drift, mutation
🗑
|

Hardy-Weinberg Equations | p+q=1
p^2+2pq+q^2=1
🗑
|
||||
Biology | study of life
🗑
|
||||
levels of organization | cellular, tissue, organ, organ system, organism, population, community, ecosystem, biosphere
🗑
|
||||
domains of life | Eukarya, Archaea, Bacteria
🗑
|
||||
Jean Baptise-Lamark | evolution came from traits acquired over an organisms life
🗑
|
||||
types of comparative anatomy | homologous, analogous, vestigial
🗑
|
||||
homologous | different function but came from the same body part on the same ancestor
🗑
|
||||
analogous | similar function but come from different sources
🗑
|
||||
vestigial | leftovers from ancestral needs
🗑
|
||||
genome | all the genetic information of an organism
🗑
|
||||
proteome | all the genetic information of an organism which codes for a protein
🗑
|
||||
gene | information which codes for a single protein
🗑
|
||||
gene pool | all the possible alleles for a certain gene within a population
🗑
|
||||
allele | possible option for a gene
🗑
|
||||
gene flow | the passage of genes in and out of a population due to immigration and emigration
🗑
|
||||
genetic drift | large changes to the gene pool of a population due to small population size (often due to chance)
🗑
|
||||
evolutionary fitness | an organisms ability to successfully reproduce and pass on its genetic information to offspring
🗑
|
||||
phenotype | the physical expression of an organism's genes
🗑
|
||||
vertical evoltuion | the passage of genetic information from generation to generation
🗑
|
||||
horizontal evolution | the passage of genetic information within a generation
🗑
|
||||
biological species concept | a species is a group which can interbreed and produce viable offspring. Speciation occurs whenever two populations become reproductively isolated
🗑
|
||||
allopatric separation | separated geographically
🗑
|
||||
sympatric speciation | distinct species within one environment
🗑
|
||||
gradualism | evolutionary change happens slowly over millions of years
🗑
|
||||
punctuated equilibrium | long periods of evolutionary stagnation followed by periods of intense evolution
🗑
|
||||
phylogenetic species concept | species are groups of populations that have been evolving independently of other groups of populations. Looks at whether there are shared derived characteristics
🗑
|
||||
types of reproductive isolation | behavioral, temporal, mechanical, gametic, ecological
🗑
|
||||
cell theory | all living things are made of cells, cells come from other cells
🗑
|
||||
behavioral isolation | mating rituals
🗑
|
||||
temporal isolation | different mating seasons
🗑
|
||||
mechanical | it doesn't fit
🗑
|
||||
gametic | the gamete cannot form
🗑
|
||||
ecological | they occupy different parts of their environments and so rarely interact
🗑
|
||||
adaptive radiation | whenever a new environment with ample resources and low competition occurs, a species may evolve into many similar species, each well adapted to their environment
🗑
|
||||
major categories of domain eukarya | plants, fungi, protists, animals
🗑
|
||||
types of evolution | directional, stabilizing, disruptive
🗑
|
||||
stabilizing evolution | favors the intermediate and eliminates the extremes
🗑
|
||||
disruptive evoltuion | favors the extremes and eliminates the intermediates
🗑
|
||||
directional evolution | favors one extreme
🗑
|
||||
ecosystem | the biological community and the surrounding environment
🗑
|
||||
biological community | all the populations in an environment
🗑
|
||||
polypoloidy | having three or more sets of chromosomes
🗑
|
||||
Jean Baptise-Lamark's theory | acquired trait inheritance
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
