Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, Extinction: students must apply extinction factors to unfamiliar species using evidence from a scenario.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Extinction because students must apply extinction factors to unfamiliar species using evidence from a scenario.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Extinction.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Extinction because students must apply extinction factors to unfamiliar species using evidence from a scenario.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Extinction because students must apply extinction factors to unfamiliar species using evidence from a scenario. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must apply extinction factors to unfamiliar species using evidence from a scenario, so the answer must stay inside Extinction. 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..
