Answer
1. Q. Vestigial structures2. V. Biochemistry3. D. Gene flow
Explanation
1. Vestigial structures are anatomical remnants that were functional in the organism's ancestors but are now useless or have reduced function. The wings of flightless birds, like the ostrich, are such structures.2. Biochemistry involves studying nucleic acids and proteins to reveal evolutionary relationships among species by comparing their molecular compositions.3. Gene flow (or migration) occurs when individuals move from one population to another, causing an exchange of genetic material which can affect allele frequencies within the populations involved.
