variation Flashcards
describe a prokaryote
70s ribosomes
peptidogylcan cell wall
no nucleus
no cell wall
describe the phototrophic kingdom
they get their energy via photosynthesis
what’s variation
inherited or environmental diversifications between individuals
what does interspecific mean
existing between diff species
what does intraspecific variation mean
occurring within a species
give 5 examples of inherited and environmental characteristics
height
leaf length
foot size
arm length
number of leaves
what is a discontinuous value
any value that is in a continuous range such as hair colour that is in a distinct category and is qualitative
what is a continuous value
something such as heart rate that isn’t in a distinct category and is quantitative
what is a homologous species
a species with a similar structure but doesn’t have the same function such as the limbs of humans, bats, whales etc
what does analogous mean
features are different in structure however they have the same function and there is no common ancestor
what does synthetic medicine mean
medicine made in a lab that is artificially created
which kingdom does black sigota belong to
fungi kingdom
what’s affected by black sigota
banana plants
why is variation important
it creates and maintains stable ecosystems
reduces the chances of genetic defects
allows evolution to occur
populations have a better chance to cope with environmental changes
example of interspecific variation
great hounds and pugs are an example
