Analogous structures have a different evolutionary ancestries but they have the same function
while homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism
Answer:
a plant hormone which promotes leaf detachment, induces seed and bud dormancy, and inhibits germination.
The effect differs. It could produce a different amino acid in the sequence because the corresponding codon has changed. It could also prevent the production of the originally intended sequence by changing one of the amino acids of a "start" codon (aka AUG) or extend the protein's sequence by modifying a "stop" codon (UAA, UAG, UGA or UGG), producing a new protein that might be useless or have different effects on the cell.
Supply oxygen to cells for cellular respiration.
