Unit One-Week One Quiz Flashcards
Morphology
-structure and form of organisms
phylogeny
-evolutionary history of a species
morphological species concept
-compares measurements & description of similar organisms
-after comparison scientist decide wether similar organisms represent different species
biological species concept
*mating concept
if two individual organisms can mage under natural circumstances and produce off spring that can successfully live and reproduce, then the two species are the same
phylogenetic species concept
a organisms is defined as a cluster of cells distinct from other clusters and shows a pattern of relationships amount organisms
how do you use binomial nomenclature when naming organisms
- Genus (capitalized)
- species name
*italicized
*underlined when hand written
how does the hierarchy of classification work
most general to most specific
what is a taxonomic category
used to classify
what are the 8 nested categories of taxonomic categories called (general term)
rank, each rank is called a taxon
list the 8 classification taxons
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
(Doctor Kevin Phil Came Over For Good Soup)
Physiology + examples
branch of biology dealing with physical and chemical functions of organisms
*including internal process
ex: comparing proteins, degree of genetic similarity or difference
DNA evidence of relationships- what are genes
genes are sections of DNA made of long chains of molecules called nucleotides
what are phylogenetic trees used for
used to represent a hypothesis about evolutionary relationships among organisms
what is a clade
a section of a phylogenetic tree that allows you to see descendants of common ancestors
what are the 3 domains
bacteria, archea, and eukarya
what is species diversity
the variety and abundance of a species in a given area
genetic diversity
the variety of heritable characteristics (genes) in a population of interbreeding individuals
what do genes control
-expression and inheritance of traits
*variation in individuals is a result of the differences in their genes
what is the gene pool
*genetic diversity within a population
sum of all the versions of all the genes of all the genes in a population
what do genetic diversity support
resistance to disease- if genes are all the same, if 1 can’t survive none could
conservation biology- use knowledge to help struggling populations
biotic
living
abiotic
non-living
ecosystem services
benefits experienced by organisms provided by sustainable ecosystem
ecosystem function & species diversity
ecosystems with greater species diversity are more likely to provide important services reliably
ecosystem services and human actions example
sometimes humans make chance to an ecosystem to enhance the services of the ecosystem
ex: stocking a lake with fish
