A physician that doesn't observe proper sterile technique may introduce bacteria from the environment into the genitourinary tract of a woman during delivery of a child, inducing puerperal fever several days later. B. The trauma of the delivery of the placenta through the vaginal tract after the fetus introduces bacteria directly into the bloodstream, resulting in puerperal fever. C. A woman's own normal fecal microbiota can occasionally cause puerperal fever if it contaminates the genitourinary tract following delivery. This can especially occur after an episiotomy procedure (cutting between the vaginal opening and the rectum). D.

Embryonic cell cycles allow the rapid division of cells in the early embryo. These mitotic cell cycles are much shorter in length than the mitotic cell cycles of cells in a mature organism. In the embryonic cell cycles, mitosis takes approximately the same amount of time as it does in the cell cycles of mature cells. What do you think is a result of the embryonic cycle?
A. Resulting daughter cells do not contain the same genetic information as the mother cell in the embryonic cell cycles. B. Mother cells in the embryonic cell cycle spend the majority of their time in G0. C. Resulting daughter cells cannot form a mitotic spindle in the embryonic cell cycle. D. Resulting daughter cells are smaller than the mother cell in the embryonic cell cycles.
