jean baptiste lamarch proposed that organisms
a have an innate tendency toward complexity and perfectio
b have an innate tendency to become simpler as time passes
c inherit all of the adaptations they display
d belong to species that never change
the same kinds of cells that grow in similar patterns in different but related organisms produce
a homologous structures such as wings and arms
b the same kind of embryos
c natural variations in a population
d descent with modifications
an example of a single gene trait is
a widows peak in humans
b weight of human infans at birth
c height in humans
d beak size in the galkapagos finches
the level of chemicals in the body that speed up cellular activity is regulated by
a action potential
b feedback inhibtion
c the sympathetic nervous system
d parasympathetic nervous system
