Because they can't hold it them selves.
The correct answer is C. Dilation, strong contractions, and delivery of the baby and the placenta
Explanation:
Labor and delivery is divided into three main stages: the first stage includes the latent phase in which cervical dilation begins (3 to 5 cm) along with mild contractions and the active phase in which strong contractions occur along with complete or almost complete dilation; the second phase is the fetus expulsion or delivery in which the cervix is fully dilated and the baby is born; and the third stage is the delivery or expulsion of the placenta that occurs as the placenta separates from the uterus and is expulsed through mild contractions. Thus, stages of labor and delivery are dilation, strong contractions, and delivery of the baby and the placenta.
G1 is growth 1. This is where the cell is growing and doing normal tasks. The cell spends most of its life here.
S is synthesis. This is where DNA is being copied/replicated. This is the first step towards mitosis.
G2 is the growth 2 stage. This is where the cell is preparing for mitosis. The cell is doing final preparations in this stage.
M is mitosis. Mitosis is the process of cell division. This can further be separated into “PMAT-C” or prophase, metaphase, Anaphase, Telophase, and Cytokinesis.
