Crossing two pink snapdragons yields some seeds that produce red-flowering plants, some seeds that produce white-flowering plants and some seeds that produce pink-flowering plants. If this trait operates by incomplete dominance and the allele R represents red flowers and the allele r represents white flowers, what genotype would a plant with pink flowers have for this trait

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
