Which option gives the correct cause-and-effect relationship for Variation and evolution, Evolution: students must describe evolution as a change in inherited characteristics of a population over time.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Evolution because students must describe evolution as a change in inherited characteristics of a population over time.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Evolution.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Evolution because students must describe evolution as a change in inherited characteristics of a population over time.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Evolution because students must describe evolution as a change in inherited characteristics of a population over time. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must describe evolution as a change in inherited characteristics of a population over time, so the answer must stay inside Evolution. The alternative options are wrong because they either treating dna as if it always means one gene., calling a gene a whole chromosome., or drift away from when asking about dna, test molecular structure, base sequence, nucleotides, or genetic information storage..
