Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, Resistant bacteria: students must describe why doctors should not prescribe antibiotics inappropriately, including for non-serious or viral infections.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Resistant bacteria because students must describe why doctors should not prescribe antibiotics inappropriately, including for non-serious or viral infections.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Resistant bacteria.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Resistant bacteria because students must describe why doctors should not prescribe antibiotics inappropriately, including for non-serious or viral infections.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Resistant bacteria because students must describe why doctors should not prescribe antibiotics inappropriately, including for non-serious or viral infections. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must describe why doctors should not prescribe antibiotics inappropriately, including for non-serious or viral infections, so the answer must stay inside Resistant bacteria. 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..
