Science
Phenotype - ANSWEROrganism's physical appearance; visible trait
Adaptation - ANSWERA behavior or physical characteristic that allows an
organism to survive or reproduce in its habitat
Asexual reproduction - ANSWERReproductive process involving only one
parent and produces offspring identical to the parent
Alleles - ANSWERDifferent forms of a gene

producer
Behavior - ANSWERAll the actions an animal performs
Binomial nomenclature - ANSWERTwo part scientific naming system for
organisms including genus and species
,Biotic factor - ANSWERA living part of an organism's habitat

returns important materials to the soil
DNA - ANSWERDeoxyribonucleic Acid; genetic material that carries
information for replication
