Which option gives the correct cause-and-effect relationship for Variation and evolution, Cloning (biology only): students must describe inserting the embryo into a womb after it has developed into a ball of cells.

The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Cloning (biology only) because students must describe inserting the embryo into a womb after it has developed into a ball of cells.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Cloning (biology only).

The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Cloning (biology only) because students must describe inserting the embryo into a womb after it has developed into a ball of cells.. Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Cloning (biology only) because students must describe inserting the embryo into a womb after it has developed into a ball of cells. is correct because Mitosis maintains chromosome number; meiosis halves chromosome number. The learning objective says students must describe inserting the embryo into a womb after it has developed into a ball of cells, so the answer must stay inside Cloning (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..
