Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Theory of evolution (biology only): students must explain that individuals best suited to the environment are more likely to survive and breed successfully.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that individuals best suited to the environment are more likely to survive and breed successfully.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Theory of evolution (biology only).

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that individuals best suited to the environment are more likely to survive and breed successfully.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that individuals best suited to the environment are more likely to survive and breed successfully. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that individuals best suited to the environment are more likely to survive and breed successfully, so the answer must stay inside Theory of evolution (biology only). The alternative options are wrong because they either calling a gene a whole chromosome., explaining protein coding without naming the gene as the relevant section of dna., or drift away from when asking about genes, test a section of dna, protein coding, alleles, or inherited characteristics..
