Hey Rob! Heading to school? There will be a quiz today for Bio lesson today! Wanna practice with me?
Hi Liz! Sure, let's practice! Gotta be prepared!
The sperms that will travel to the fallopian tube could only have access to go in the egg cell if it completely connects with it.
Okay, so the ovaries produce 1 egg which will later travel through the fallopian tube. There, the egg would mature and be fertilized by the sperms.
The chromosomes from the two would attach to one another tightly until both DNA are on one another. Then the mitosis process with start.
Yes, later the sperm will produce enzymes to break down the walls of the egg cell. The egg cell then would bring in the sperm in it.
5th day is when the embryo becomes a blastocyst and the 6th or 7th is the day of implantation of blastocyst. Differentiation is the process of types of cell differentiating to other roles.
So simple summary after the process of mitosis starts is, blastocyst -> Implantation -> Differentiation-> Gastrulation -> Neurulation -> Placenta Development -> Trimester 2 and 3 -> Birth
Gastrulation would be specialization of the three layers: ectoderm, mesoderm and endoderm. Ectoderm -> skin and nervous system. Mesoderm -> internal body structure. Endoderm -> linings of organs
Neurulation: Mesoderm form the notochord -> Ectoderm folds inward, forming a groove -> process is completed with the formation of the neural tube. Somites and the coelom also develop.
The first trimester= Brain, spinal cord, and other organs begin to form including the eyes and ears. Process will be from week 1-12.
Yes, 9 months are needed for the baby to grow. For the first to eight weeks the baby is call an embryo. In the twelfth week it will be called a fetus.
Then, the placenta development will help the fetus with receiving oxygen and food, and taking away waste from the baby through the umbilical cord.
The second trimester= The fetus will start moving and, the ears and eyes will start to move to its intended location. The fetus could now hear voices outside. Process will from week 13-26.
The third trimester= The fetus would grow rapidly in weight and size. The organs would all mature and the baby's head would be positioned head down. Process is from week 27-39/40
Your very welcome Rob.
The mother will later have her water broken and go into labor to deliver the baby. The pelvic floor muscle muscle will help with the pushing of the baby..
Oh, right! Almost forgot that one. Well, thanks Liz for the practice, hope you'll ace the quiz.
