Variation and evolution
Question
- A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must explain that variation may be caused by inherited genes.
- B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Variation.
- C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on explain that variation may be caused by inherited genes.
- D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Variation.
Answer
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must explain that variation may be caused by inherited genes.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Variation.
Explanation
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must explain that variation may be caused by inherited genes.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must explain that variation may be caused by inherited genes. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that variation may be caused by inherited genes, so the answer must stay inside Variation. 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
Variation common mistake 1
Giving a vague answer instead of directly addressing: Explain that variation may be caused by inherited genes..
Answer by clearly explaining how to explain that variation may be caused by inherited genes..
