What is evidence that menopause is an adaptive cooperative trait? In humans, the presence of reproductive (fertile) grandmothers probably increases the survival rate of their grandoffspring. O In killer whales, the presence of reproductive (fertile) grandmothers increases the survival rate of their grandoffspring. In both humans and killer whales, the presence of non-reproductive grandmothers probably increases the survival rate of their grandoffspring. In humans, the presence of reproductive (fertile) mothers increases the survival rate of their reproductive grandparents.

Which statement about menopause is most correct? A. Menopause has to be adaptive because life-history theory predicts that women should not outlive their reproductive capacity, so menopause must have some function. B. Menopause has to be adaptive because humans, not chimpanzees, experience menopause, and humans are evolutionarily more advanced than chimps. C. Several hypotheses for menopause as an adaptation have been proposed, but more evidence is necessary to support any one of them. D. Several hypotheses for menopause as an adaptation have been proposed, but they have not been tested.
Some animals like Aphids, sea anemones, starfishes, sea stars can reproduceasexually and sexually. What will be the advantage and disadvantage ofproducing through asexual and asexual method?
Sexual reproduction results in offspring that are genetically different from one another and from their parents. Describe four mechanisms that produce this genetic variation. Do any of these mechanisms occur in asexualreproduction?
The endometrium thickens during the uterine cycle, but disintegrates if the egg is not fertilized. The disintegration and shedding of the endometrium is caused by a drop in progesterone levels an increase in estrogen levels by increase in human chorionic gonadotropin levels a drop in prolactin levels
Parthenogenesis is the most common form of asexualreproduction in animals that at other times reproducesexually. What characteristic of parthenogenesis mightexplain this observation?
What are the general characteristics of sexual reproduction in humans and other vertebrates that are associated with continuous production of many sperm cells but intermittent, finite production of egg cells?
Describe a positive feedback mechanism that contributes to ovarian cycling. If the ovulated oocyte becomes fertilized, what causes ovarian cycling to stop for the duration of the pregnancy? On approximately what date(s) would Anita have her highest estrogen levels On what date(s) would Anita most likely have a successful fertilization?
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 testis
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.
Compared to separate sexes and assuming self-fertilizing is not possible, what might be one advantage and one disadvantage to hermaphroditism?
Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.
