By the time a cell has reached metaphase, all the following have occurred except...

C. Sister chromatids separate

Explanation:

During interphase, which is composed of the G1 phase, S phase and G2 phase, the cell grows and replicates its DNA and some of its organelles. During the S phase, the genetic material is duplicated into two sister chromatids, and centrosomes, which are nucleated microtubules that interact with the chromosomes to form the mitotic spindle, are also replicated. Metaphase is the third phase of mitosis, where sister chromatids align in the middle of the cell before their separation into two daughter cells.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
