Question
- A. Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must state that knowledge of reproduction examples is restricted to the organisms named in the specification.
- B. Reversed cause: Claiming meiosis is used for body growth. This would blur Mitosis vs meiosis instead of testing Advantages and disadvantages of sexual and asexual reproduction (biology only).
- C. Missing link: Claiming mitosis produces gametes. This misses the objective focus on state that knowledge of reproduction examples is restricted to the organisms named in the specification.
- D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Advantages and disadvantages of sexual and asexual reproduction (biology only).
Answer
The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must state that knowledge of reproduction examples is restricted to the organisms named in the specification.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Advantages and disadvantages of sexual and asexual reproduction (biology only).
Explanation
The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must state that knowledge of reproduction examples is restricted to the organisms named in the specification.. Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Advantages and disadvantages of sexual and asexual reproduction (biology only) because students must state that knowledge of reproduction examples is restricted to the organisms named in the specification. is correct because Mitosis maintains chromosome number; meiosis halves chromosome number. The learning objective says students must state that knowledge of reproduction examples is restricted to the organisms named in the specification, so the answer must stay inside Advantages and disadvantages of sexual and asexual reproduction (biology only). The alternative options are wrong because they either claiming meiosis is used for body growth., claiming mitosis produces gametes., or drift away from mitosis questions must focus on identical cells, growth, repair, asexual reproduction, or maintained chromosome number..
Common mistake
Assuming all organisms can be classified as either sexual or asexual
Students often think that any organism not listed in the specification can be described as either sexual or asexual, ignoring the restriction that only the organisms named in the specification are required for examples.
Remind students that the specification explicitly limits reproduction examples to the organisms named in the specification; they should not provide examples from other species unless those species are listed in the specification.
