Living organisms that are capable of producing both egg and sperm
Step by step
Solved in 3 steps
- Figure 18.17 Which of the following statements about hormone regulation of the female reproductive cycle is false? a. LH and FSH are produced in the pituitary, and estrogen and progesterone are produced in the ovaries. b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. c. Both progesterone and estrogen are produced by the follicles. d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estrogen but stimulated by high levels of estrogen.Besides producing gametes (sperm and eggs), the primary male and female reproductive organs also produce sex hormones. The _____ and the pituitary gland control secretion of both.Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
- Compared to separate sexes and assuming self-fertilizing is not possible, what might be one advantage and one disadvantage to hermaphroditism?In a human zygote, the cell divisions of cleavage produce an embryonic stage known generally as a _______. a. zona pellucida b. gastrula c. blastocyst d. larvaFigure 18.12 Which of the following statements about the male reproductive system is false? a. The vas deferens carries sperm from the testes to the seminal vesicles. b. The ejaculatory duct joins the urethra. c. Both the prostate and the bulbourethral glands produce components of the semen. d. The prostate gland is located in the testes.
- How Is Sex Determined? The absence of a Y chromosome in an early embryo causes the: a. embryonic testis to become an ovary b. Wolffian duct system to develop c. Mllerian duct system to degenerate d. indifferent gonad to become an ovary e. indifferent gonad to become a testisFigure 43.8 Which of the following statements about the male reproductive system is false? The vas deferens carries sperm from the testes to the penis. Sperm mature in seminiferous tubules in the testes. Both the prostate and the bulbourethral glands produce components of the semen. The prostate gland is located in the testes.Which of the following is NOT true regarding spermatogenesis? Initial spermatozoa formed are not mobile and cannot fertilize. Spematogonia have diplold chromosome. Spematocyte undergoes two rounds of division to produce 4 diploid sperm Some of the spermatogonia become reservoir cells Spematogonia breaks away from the basement membrane to develop Into sperm.
