Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, Extinction: students must describe habitat change or loss as a possible contributor to 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 describe habitat change or loss as a possible contributor to extinction.. 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 describe habitat change or loss as a possible contributor to extinction.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Extinction because students must describe habitat change or loss as a possible contributor to extinction. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must describe habitat change or loss as a possible contributor to extinction, 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..
