Equations can be balanced by using the half-reaction method. Which step should be completed first when using this method? inserting the coefficients
balancing the half reactions
identifying the half reactions
finding the oxidation states of atoms

Which supports the idea that birds and butterflies both have wings but they do not have a common ancestor with wings? a. the wings are analogous structures that evolved differently and do not have a similar internal structure. b. the wings are homologous structures that evolved differently and do not have a similar internal structure. c. wings of birds are vestigial structures, but the wing structures of bats are not vestigial. d. wings of bats are vestigial structures, but the wing structures of birds are not vestigial
