The development of understanding of genetics and evolution

Question

A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Extinction because students must describe habitat change or loss as a possible contributor to extinction.
B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Extinction.
C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on describe habitat change or loss as a possible contributor to extinction.
D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than The development of understanding of genetics and evolution / Extinction.

Answer

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. 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.

Explanation

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Extinction because students must describe habitat change or loss as a possible contributor to extinction.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Extinction because students must describe habitat change or loss as a possible contributor to extinction. is correct because DNA can contain many genes; a gene has a specific coding role. 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 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..

Common mistake

Extinction common mistake 1

Giving a vague answer instead of directly addressing: Describe habitat change or loss as a possible contributor to extinction..

Answer by clearly explaining how to describe habitat change or loss as a possible contributor to extinction..
