Diversity and classification Flashcards
what is a species
organisms with similar biochemistry
that can reproduce to create fertile offspring
what is a hierarchy
groups within groups with no overlap
what are the eight taxa used in classificaion
domain kingdom phylum class order family genus species
what is each group in classification called
a taxon, plural taxa
what is the binominal naming system
Genus Species
what is courtship behaviour
it is carried out by organsims to attract a mate of the right species
how can courtship behaviour be used to classify species
as it is species specific only members of the same species will do and respond to that courtship behaviour
what is the link between how closely related species are and their courtship behaviour
due to the fact it is species specific
more closely related a species is
more similar courtship behaviour is
how can genome sequencing be used to see how closely related organsims are?
DNA base sequence of one organism can be then compared to the DNA base sequence of another organism
closely related species have a higher % of similarity in their DNA base sequence
how can comparing amino acid sequences be used to see how closely related organisms are?
related organisms have similar DNA sequences so
Related organisms have similar amino acid sequences
in proteins
how can immunlogical comparisons be used to see how closely related organisms are?
similar protiens will bind to similar antibodies
what are the two causes of variation
genetic factors
enviromental factors
what is biodiversity
the variety of living organisms in an area
what is a habitat
a place where organisms live
what is a community
all the populations of all the different species in a habitat
