true

Explanation:

the majority of mutations are neutral in their effects on the organisms in which they occur . beneficial mutations may become more common through natural selection. harmful mutations may cause genetic disorders or cancer :))

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.
