Which of the following scenarios is an example of sequential hermaphroditism? Hamlet fish typically contain both male and female sexual organs and can mate as both male or female on the same day When male striped maple trees are sick or damaged, their sex will change to female When turtle eggs incubate at high temperature, the hatchlings will be female. When they incubate at low temperatures, the hatchlings will be male Vipers typically sexually reproduce, but can asexually reproduce when kept in captivity

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.
Which of these is an example of asexual reproduction? A hermaphrodite mating with another hermaphrodide A female lizard producing embryos via parthenogenesis Different corals producing either sperm or eggs and releasing them into the water during spawning where they are fertilized externally Mating between a male and female birds
Fishes and some species of amphibians like frogs fertilize their eggs outside of their body. Which of the following statements is TRUE about external fertilization? * A small number of gametes need to be produced by the male and female to ensure reproductive success It produces a small number of offspring compared to internal fertilization A body of water is not required no answer Chances of fertilization are diminished by environmental hazards and Predators
We discussed environmental sex determination in reptiles, where the sex of the individual is determined by environmental factors rather than chromosomes. Which of the following modes of sex determination would also fit that category? hermaphroditic earthworms hermaphroditic hermaphroditic all of the above nudibranchs (the "penis fencers") coral reef fish
Living organisms that are capable of producing both egg and sperm have both male and female reproductive organs are gonochoric are hermaphroditic both A and C are correct
Which of the following describes the role of Luteinizing hormone in the ovarian cycle? o Inhibits the hypothalamus from secreting GNRH o Directly promotes thickening of the endometrium o Simulates the ovary to increase aldosterone o Induces the corpus luteum to secrete progesterone Stimulates lactation in the mammary glands
Which of the following is NOT one of the events leading to male sex-determination in humans? The Wolffian ducts are degraded. TDF and SF1 stimulate transcription of SOX9. Testosterone is produced, which stimulates the development of male reproductive structures and other male secondary characteristics. Mullerian-Inhibiting Hormone (MIH) is produced. The SRY gene is expressed to produce Testes-Determining Factor (TDF).
Define two alternatives to bisexual reproduction-hermaphroditism and parthenogenesis and offer a specific example of each from the animal kingdom.
The graph above shows the estrogen and progesterone levels of an individual during a menstrual cycle of 28 days. The top light blue line indicates the progesterone levels and the bottom purple line indicates the estrogen levels. This individual is Answer. ( pregnant, in luteal phase , in follicular phase, entering menopause, taking oral contraceptive, in pre-ovulation phase , ovulating)This individual can be expected to have ( high , low ) levels of FSH and LH.

Listed in the table below are the five major reproductive hormones that support ovulation in female mammals, including the giant panda. Describe the role of each hormone in this process and the approximate time during the ovarian cycle that it reaches peak levels. Hormone Gonadotropin-releasing hormone (GnRH) Estrogen Luteinizing hormone (LH) Follicle stimulating hormone (FSH) Progesterone Role in Regulation of the Menstrual Cycle Timing of Peak Level
Define the two alternatives of bisexual reproduction-parthenogenesis and hermaphroditism, and give a specific example from the animal kingdom for each. Also differentiate meiotic and ameiotic parthenogenesis.
Which of the following mechanisms best explains the contraceptive effect of birth control pills that contain both synthetic estrogen and progestin?
