Question
Chapter 46.5, Problem 3CC
Summary Introduction
To explain: The steps that will be bypassed if a sperm nucleus is injected into an oocyte.
Concept introduction: Sperms are produced in the testes of males, and egg cells are produced in the ovary of females. In males, epididymis is a coiled tube that connects the testicle to vas deferens. Vas deferens is a muscular duct through which sperms are propelled out. The fusion of the sperm to egg cell completes the process of fertilization.

QUESTION 6
Although observations and experimental results implicate nAG in salamander limb regeneration, which
experiment should be done, in the regenerating limb, to provide a more definitive test of whether nAG
functions in limb regeneration?
Use transgenesis to express nAG protein in the blastema
Do in situ hybridization to know where the gene is expressed
Block the activity of the prod-1 signaling pathway with a small molecule (drug)
O Use Cre/Lox technology to knock out the function of nAG gene in the limb
WHAT IF? If a human female begins taking estradioland progesterone immediately after the start of a newmenstrual cycle, how will ovulation be affected? Explain

- 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?arrow_forwardReproductive physiology (human) a) At the time of ovulation, the released ovum (egg) has completed both meiosis I and meiosis II. b) Because the corpus luteum (CL) is rescued from atresia by hCG early in pregnancy, the CL continues to produce progesterone throughout the 9 months of a normal pregnancy. c) Late in the follicular phase, estrogen participates in a positive feedback loop that leads to a surge in luteinizing hormone and ovulation. d) Both (a) and (b) are correct and (c) is incorrect e) Statements (a), (b) and (c) are all correctarrow_forwardScenario 1: Examine the sketch of a diagram of an XY human male cell undergoing spermatogenesis.

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.
