A heartbeat has two parts the first part in the flow of the blood into the heart. The second part is the flow of the blood out of the heart. That is why heart beat is a bub-bub sound.

During the S stage DNA synthesis occurs. (copying of the DNA)
fermentation will occur.
It uses up most of the hydrogen it started with.

basically, the rubbish data comes out.
Glycolysis occurs in the cytoplasm during the first stage of respiration.
The first heartbeat typically occurs around 5 to 6 weeks after conception. At this stage, the embryo's heart begins to develop and can be detected via ultrasound. By the end of the sixth week, the heartbeat may be strong enough to be heard.

The germinal stage is the first stage of prenatal development that begins at fertilization and lasts for about two weeks. During this stage, the zygote undergoes rapid cell division and travels down the fallopian tube to the uterus, where it implants in the uterine lining. The germinal stage ends with the formation of the blastocyst, which is the early stage of embryonic development.

Answer: During the first stage of labor, the cervix will start to thin out (also called efface) and open up (also called dilate). The first stage of labor can take a couple of hours or a couple of weeks (I was in my first stage of labor with my daughter for 2 weeks). Most women usually stay at home during this stage as it is not the "active" stage of labor. The active stage of labor is stage 2. During this stage your cervix will continue to efface and dilate at a much more rapid pace. This ends with the birth of your baby. Then comes stage 3, also know as the after-birth stage. This is when you push out the placenta, which is what protected the baby for 9 months and held the fluids.

The first stage is jettisoned, to fall back to earth, as the fuel runs out.
