Variation and evolution

Question

A. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Variation because students must explain that variation may be caused by a combination of genes and environment.
B. Reversed cause: Treating DNA as if it always means one gene. This would blur DNA vs genes instead of testing Variation.
C. Missing link: Calling a gene a whole chromosome. This misses the objective focus on explain that variation may be caused by a combination of genes and environment.
D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Variation.

Answer

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Variation because students must explain that variation may be caused by a combination of genes and environment.. 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 cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Variation because students must explain that variation may be caused by a combination of genes and environment.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Variation because students must explain that variation may be caused by a combination of genes and environment. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must explain that variation may be caused by a combination of genes and environment, so the answer must stay inside Variation. 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..

Common mistake

Variation common mistake 1

Giving a vague answer instead of directly addressing: Explain that variation may be caused by a combination of genes and environment..

Answer by clearly explaining how to explain that variation may be caused by a combination of genes and environment..
