Question
Chapter 35, Problem 18WIO
Summary Introduction
To explain:
Through consulting a website, the type technology that would be necessary to enable the fetus born in fourth month to survive in laboratory setting.
Concept introduction:
The fertilization can be defined as the process in which the male sperm fuses with the female egg to produce zygote. The process of development of the fetus to the embryo is known as the prenatal development. It starts with the fertilization and ends with parturition. The total gestation period is nine months.

Emily and her husband are thrilled as they peer into Emily's uterus by means of an ultrasound. The physician reports that the pregnancy appears normal and that their baby's organs, spine, and arms and legs are developing as expected. Given this information, the current stage of prenatal development is the
embryonic period germinal period zygotic period fetal stage placenta
Explain why ultrasound imaging is the technique ofchoice for studying fetal growth and development.
Draw and label a diagram of a 7 week baby in utero.
Your diagram should include the following extra embryonic structures: chorion, amniotic cavity, allantois, endometrium, amnion, yolk sac, & developing placenta.

Jean tells the nurse that in Haiti, a multiple marker screen blood test was done, and they were told it was abnormal. Marie expresses ambivalence about the pregnancy, stating, “I’m really scared. I had a miscarriage 6 month ago. She complains of tender breasts and intermittent nausea. Her last menstrual period was June 10. 1. What is Marie’s GTPAL, and due date?

You know that since she came to college she has been experimenting with recreational drugs. Circle the best advice you could give her, and explain your choice. (a) She must stop taking the drugs, but they could not have affected her fetus during these first few months of her pregnancy. (b) Harmful substances usually cannot pass from mother to embryo, so she can keep using drugs. (c) There could be defects in the fetus, so she should stop using drugs and visit a doctor as soon as possible. (d) If she has not taken any drugs in the last week, she is OK.arrow_forward

[Discuss the life style of the developing sea urchin embryo in the water column compared to a very different ecological niche of the adults on the ocean floor. Besides, would you want to give live birth to a sea urchin! ouch!] 2: Then why don't the parents take care of the young? [In fact the adults do in a way. After the embryo has grown large enough and metamorphosed into a young urchin they hide in the spines of the adults, living off of the scraps of food produced from the messy eating of the adults] 3: Because the urchin life involves two or more ecological niches, they are more susceptible to predation and exposure to environmental toxins.
