Which of the following statement does NOT correctly describe the event of the following fertilization? Select one: A. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. B. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body. C. The trophoblast has important in maintaining the pregnancy, as it prevents the endometrium from shedding. D. Only inner cells mass in a blastocyst is pluripotent.

Which of the following statements does NOT correctly describe the events following fertilization? Select one: a. Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.
During the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum? Select one: a. The corpus luteum produces relaxin, which thickens the endometrium. b. The corpus luteum ensures that the endometrium does not break down during the first trimester. c. The corpus luteum supports the formation of the placenta. d. The chorion forms the fetal part of the placenta, and the corpus luteum supports the maternal part of the placenta.
Suppose that in the near future, you are a prenatal care provider. In the most recent ultrasound checkup on the expecting mother, you unfortunately found that the fetus is suffering a neural tube defect in the form of anencephaly. Seeing as the mother is still in the 12th week of pregnancy or the 1st trimester, the pregnancy can still be terminated via medical means. How would you explain to the parents the situation they are in?
There are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?
Which of the following is not true about neurulation? Choose all possible answers. a. Segregation of neural ectodermal rudiment from the epidermal ectoderm. b. In primary neurulation, the neural plate thickens along its midline into a solid cord of cells that is displaced internally and cavitates to form a hollow tube. c. In secondary neurulation, the neural plate folds along the anterior-posterior axis of the embryo, forming a tube that detaches from, and is displaced under, the epidermal ectoderm. d. Ectoderm forms the neural tube e. Mesoderm forms the reproductive organs f. Endoderm forms the gut g. All are true about neurulation
What happens if an oocyte combines with sperm? Describe the processes involved in implantation. Mention what is occurring, where it is occurring, and any significant hormones involved. How does the zygote make its way through the uterine tube? Women who smoke cigarettes have an increased risk of ectopic pregnancy because the chemicals they absorb paralyze cilia all through the body. Explain.
Which of the following rows correctly identifies the locations of fertilization and the development of the fertilized ovum? Select one: a. Fertilization Development of the fertilized ovum Fallopian tube Uterus b. Fertilization Development of the fertilized ovum Ovary Uterus c. Fertilization Development of the fertilized ovum Fimbriae Endometrium d. Fertilization Development of the fertilized ovum Uterus Endometrium
Which of the following rows identifies structures responsible for maintaining the endometrium before and after implantation? Select one: a. Before Implantation After Implantation Corpus luteum Placenta b. Before Implantation After Implantation Maturing follicle Placenta c. Before Implantation After Implantation Corpus luteum Trophoblast d. Before Implantation After Implantation Maturing follicle Trophoblast
Which of the following rows identifies structures responsible for maintaining the endometrium before and immediately after implantation? Select one: A. Before Implantation After Implantation Corpus Luteum Placenta B. Before Implantation After Implantation Maturing Follicle Placenta C. Before Implantation After Implantation Corpus Luteum Trophoblast D. Before Implantation After Implantation Maturing Follicle Trophoblast
Alcohol is the one of the most damaging teratogens, and it is also the easiest to avoid during pregnancy. It is unknown what the safe amount of alcohol consumption during pregnancy is. Therefore, it is recommended that pregnant and breastfeeding women do not consume any amount of alcohol to prevent fetal alcohol syndrome in newborns.Symptoms of the fetal alcohol syndrome include all of the following EXCEPT Select one: a. a lack of oxygen delivered to fetal lungs b. a smaller or absent corpus callosum c. a smaller birth weight, length, and head circumference d. a learning disability, personality disorder, and facial malformation
Superovulation is when women take hormones in order to release more eggs for fertilization. Which of the following rows contains hormones that are involved in developing the follicles and releasing them from the ovary, respectively? What could be the unintended consequence of this process? Select one: a. Hormone Unintended Consequence FSH and LH The formation of twins or multiple births b. Hormone Unintended Consequence FSH and LH A tubal ligation c. Hormone Unintended Consequence FSH and LH Scar tissue on the Fallopian tubes d. Hormone Unintended Consequence LH and FSH Ovarian Cancer
One day while walking across campus, you see a female butterfly laying fertilized eggs, as shown in the image: 1. What type of ovarioles would the adult female butterfly have (hint: remember the Order of butterflies)? a. Panoistic ovarioles b. Plasmatocytic ovarioles c. Polytrophic ovarioles d. Collaterial ovarioles e. Telotrophic ovarioles 2. Which combination of mechanisms would the butterfly use to supply vitellogenins/maternal mRNAs to the developing oocytes? a. Follicular epithelial cells/trophocytes contained within the follicle b. Apical cells of germarium/nutritive cords c. Follicular epithelial cells/nucleus of the oocyte d. Prefollicular tissue in germarium/trophoocytes that remain in germarium 3. Which statement is correct with respect to the hormonal regulation of the development of the ovaries and vitellogenesis in the adult female butterfly? (Hint: the processes are the same as in a female mosquito.) a.…
