3.) Roughly 3 days after fertilization in the ampulla of the human fallopian tube, the morula:

I.) develops a blastocoel.
II.) contains about 16 blastomeres.
III.) passes into the uterus.
IV.) forms an outer cell layer called the trophoblast.

A.) I and II only
B.) II and III only
C.) III and IV only
D.) I and IV only

@BerkReviewTeach

I got this question correct because I knew that I and IV are qualities of the blastula, and not the Morula so only B could be correct.

This is probably trivial but its annoying me.

My question is in the chapter the book describes the morula as containing 32 cells or blastomeres. Is the statement in II. (16 blastomeres) correct simply because it was worded as "about 16" ?

Thanks.
