Ψ Note: These inquiries are component of a larger data base of questions on Chapter 4 & space selected to stand for the kind of question you should expect ~ above unit test one. You can, in fact, suppose to see numerous of these an extremely same inquiries on that exam. Test questions, however, may deal with topics not covered in the self tests or in lectures yet are debated in her textbook. You space responsible because that the contents of her text publication plus the content of lectures, interactive activities, & material on the web site. Use these sample concerns to test you yourself & to exercise for the test. Click your an option to check out if you are right.

You are watching: The critical factor in attaining the age of viability is

1. The Apgar scale is administered • once, just after birth. • only if the child is in noticeable distress. • repeatedly during the newborn"s first hours. • twice, one minute and five minutes after birth. 2. The neural pipe becomes the • backbone. • minister tract. • reproductive organs. • mind & spinal cord. 3. The most an essential factor in attaining the age of viability (22 weeks) is the development of the • placenta. • eyes. • brain. • skeleton. 4. A teratogen is a substance or a problem that can cause birth defects. A cell through extra chromosomes. waste products from the embryo. damages sustained come the placenta. 5. to say the a teratogen has actually a “threshold effect” way that it is: harmful only to low-birthweight infants. practically harmless until exposure get a details level. harmful to details developing organs when those offal are developing most rapidly. harmful just if the pregnant woman’s weight does not rise by a specific minimum amount during her pregnancy. 6. Pregnant females who room HIV- hopeful should always have abortions. have the right to reduce the threat of infecting their fetuses by having monthly HIV tests. can reduce the risk of infecting their fetuses by preventing a Cesarean delivery. can reduce the danger of infecting their fetuses by taking AZT. 7. The 3rd through the 8 hours week after conception is called the: fetal period. ovum period. germinal period. embryonic period. 8. Normally, throughout birth the placenta is expelled first. the head increase first. the labor procedure takes approximately ten hours. the labor procedure takes much longer for the second pregnancy.9. The most usual teratogen in arisen nations is • alcohol. • caffeine. • nicotine. • pesticide exposure. 10. Anoxia describes a lack of oxygen. cerebral hemorrhaging. indicators of cerebral palsy. toxins in the blood. 11. during the germinal period, the very first task of the external cells is come implant in the uterus. discover a permanent place in the ovaries. division as fast as possible. distinguish into different types of tissue. 12. The fetus starts to build male sex guts if • the X chromosome send a biochemical signal. • the Y chromosome send a biochemical signal. • the understand signal from the Y chromosome overrides the X signal. • no biochemical signal is produced.
13. Preterm bear is • more common in Japan the US. • much more common in home deliveries. • sometimes led to by epidemic in the mother. • an ext likely to happen with upper-class mothers.

14. research in genetic vulnerability come teratogens has uncovered that female embryos are more vulnerable than males. genetic vulnerability guarantees a bear defect of part sort. fraternal twins are equally vulnerable. the XY chromosome sample is much more susceptible come damage. 15. A complete Apgar the 3 means a newborn is in terrific condition. Has an LBW. is in an important condition. is irritable and may be sneeze or crying. 16. Kangaroo treatment refers to: the fragmented care that the kids of solitary parents regularly receive. a program of increased involvement by mothers of short birth-weight infants. the rigid attachments formed between mothers & offspring in the animal world. nobody of these apply! 17. Synaptogenesis describes the procedure by which; the fetal mind develops new neurons. new connections between neurons develop. the neural tube forms throughout the middle trimester. the cortex folds right into layers in order to fit right into the skull. 18. The vital period for staying clear of physical defects shows up to be the fetal duration zygote duration whole pregnancy embryonic duration 19.

Neurogenesis refers to the procedure by which; the fetal mind develops brand-new neurons. new connections between neurons develop. the neural tube forms throughout the middle trimester. the cortex folds right into layers in order come fit into the skull. 20. In order, the exactly sequence the prenatal advance is • embryo; germinal; fetus. • germinal; fetus; embryo. • germinal; embryo; fetus. • ovum; embryo; fetus.
