Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?

A. Meiosis must occur at some point in the life cycle to prevent a doubling of chromosomes in each generation. B. Mitosis must occur at some point in the life cycle to prevent a reduction of chromosomes in each generation. C. The diploid stage allows for genetic recombination. D. Meiosis must occur at some point in the life cycle to prevent a reduction of chromosomes in each generation. E. Haploid cells cannot grow independently of diploid cells.

What would you expect to happen if the anaphase-promoting complex/cyclosome (APC/C) failed to ubiquitinate securin?

A. The cohesin complex will persist, preventing the cell from entering anaphase. B. Securin will remain intact and therefore will degrade cohesin, allowing the cell to enter anaphase. C. The cohesin complex will be destroyed, and the cell will remain in metaphase. D. Separase will be marked for degradation by securin, preventing the cell from entering anaphase.
