Question
Chapter 52, Problem 1A
Summary Introduction
Introduction:
Fertilization is the fusion of haploid male gamete (sperm) with haploid female gamete (ovum) that results in the formation of diploid zygote. Twins are the product of two offsprings from same zygote. Twins can be identical (monozygotic twins) or fraternal (dizygotic twins).

- How can PID (pelvic inflammatory disease) lead to infertility in women? Select one: a. PID can lead to scar tissue developing on the Fallopian tube. This prevents the egg and the sperm from meeting, causing infertility. b. PID prevents the endometrium from forming. There is not enough material for the fertilized egg to implant itself. c. PID leads to scar tissue on the corpus luteum. This disrupts ovulation. d. PID affects the cervix. This causes the cervix to swell, decreasing the chance a sperm could pass into the uterus.arrow_forwardIt is no mystery how harmful a lot of environmental factors can be on a fetus nor is it misunderstood how important proper prenatal care is during pregnancy.

- A couple living in Florida is trying to have a baby, but they are having trouble getting pregnant. The male is very light skinned yet enjoys spending as much time as possible outdoors in the sun. From the male's perspective, why might he be contributing to the trouble with getting pregnant? Excessive ultraviolet light exposure can reduce folate levels, and folate is required for normal sperm development. Excessive heat from the sunlight inhibits normal sperm production; thus, he probably does not have enough sperm. The male does not have enough melanin production to support normal sperm development. Excessive sunlight exposure can rapidly increase folate levels, which then inhibits normal sperm development. Normal sperm development occurs best in colder temperatures; thus, living in Florida he has a reduced chance of getting his partner pregnant.arrow_forwardOne 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.
