Which structures control the cyclic nature of menstruation? (1) pituitary and ovaries (3) pituitary and testes (2) ovaries and umbilical cord (4) oviduct and uterus 9. Substances can diffuse from the mother's blood into the fetal blood through the structure known as the (1) amnion (3) yolk sac (2) fallopian tube (4) placenta The corpus luteum forms in structure 2. (1) A (3) C (2) B (4) D 10. Base your answer to the following question on the diagram below which represents structures found in a female mammal's reproductive system and some processes which might occur within that system. 3. The cervix is represented by structure (1) A (3) C (2) B (4) D 4. In human females, the growth of follicle cells is stimulated by (1) estrogen (3) FSH (2) progesterone (4) LH 5. Base your answer to the following question on the information below and on your knowledge of biology. Some women are unable to have children because of a blockage in that portion of their reproductive tract where fertilization of the egg cell would normally occur. In vitro fertilization is a technique that has been developed to make it possible for such women to bear their own children. This technique involves fertilizing an egg in a sterile petri dish environment and then implanting the developing embryo into the mother. An embryo that developed as a result of in vitro fertilization would be implanted in the mother's (1) ovary (3) uterus (2) oviduct (4) vagina 6. Thickening and vascularization of the uterine lining in the human female is initiated during which stage of the menstrual cycle? (1) follicle (3) corpus luteum (2) ovulation (4) menstruation The structure labeled B represents (1) a zygote (3) an ovary (2) an egg (4) a follicle 11. In which stage of the human menstrual cycle does an egg mature in an ovary? (1) Menstruation (3) Ovulation (2) Corpus luteum stage (4) Follicle stage 12. The normal reproductive cycle of the human female involves the interaction of the (1) oviduct, thyroid gland, and ovary (2) pituitary gland, ovary, and uterus (3) adrenal gland, ovary, and vagina (4) placenta, pituitary gland, and uterus Page 1

2 13. Base your answer to the following question on the diagram below, the cartoon below, and your knowledge of biology. Structure A is considered part of both the reproductive system and the (1) excretory system (2) circulatory system (3) endocrine system (4) digestive system 14. Which diagram best represents part of the process of sperm formation in an organism that has a normal chromosome number of eight? (1) (3) 18. Base your answer to the following question on the diagram below and on your knowledge of biology. The diagram represents some of the stages in the reproduction and development of a vertebrate. (2) (4) 15. In human females, the release of a gamete from a follicle is known as (1) menstruation (3) menopause (2) ovulation (4) gametogenesis 16. Regulation of sexual reproductive cycles of human males is related most directly to the presence of the hormone (1) insulin (3) progesterone (2) testosterone (4) estrogen 17. In humans, the period of development before birth is known as (1) pollination (3) fertilization (2) menstruation (4) gestation In which part of the human female reproductive tract does the event represented by A normally occur? (1) vagina (3) oviduct (2) uterus (4) ovary 19. In the human male, both the synthesis of hormones and the production of monoploid cells occur in the (1) testis (3) penis (2) urethra (4) bladder Page 2

3 20. Base your answer to the following question on the diagram below of the male reproductive system and on your knowledge of biology. 22. A diagram of human female reproductive structures is shown below. Which structure is correctly paired with its function? (1) A releases estrogen and progesterone (2) B produces and releases the egg (3) C provides the usual site for fertilization (4) D nourishes a developing embryo 23. When asked to relate the terms "sperm," "scrotum," "testes," and "zygote," a student wrote the statements below. Which structures are glands that secrete a liquid for the transport of sperm? (1) A and D (3) C and H (2) B and E (4) F and G 21. Base your answer to the following question on the information in the chart below and on your knowledge of biology. Statements (A) They all contain homologous pairs of chromosomes. (B) The location of the testes within the scrotum aids in the production of sperm needed for zygote formation. (C) Mitotic cell division is involved in the formation of the testes and scrotum, and meiosis is involved in the production of sperm, which is involved in the formation of a zygote. (D) Formation of the testes, scrotum, and sperm occurs in human males; zygote formation occurs in females. Which statements are correct? (1) A, B, and D, only (3) B and D, only (2) B, C, and D, only (4) A, B, C, and D 24. After one primary sex cell in a human testis undergoes meiosis, the usual result is (1) one monoploid cell (3) four diploid cells (2) four monoploid cells (4) one diploid cell 25. Identical twins would result from the (1) fertilization of two eggs (2) eggs from the same ovary (3) same zygote (4) formation of different zygotes Which stage is represented by letter A? (1) corpus luteum (3) menstruation (2) follicle (4) ovulation 26. The permanent cessation of the menstrual cycle is known as (1) gestation (3) vascularization (2) puberty (4) menopause Page 3

4 27. Base your answer to the following question on the following information. The diagrams below represent organs of two individuals. The diagrams are followed by a list of sentences. For each phrase, select the sentence from the list below that best applies to that phrase. Then record its number in the space provided. Contains organs that produce gametes 28. The diagrams below represent the reproductive systems in the human male and female. The blockages shown at A and B would most likely interfere with the ability to (1) transport gametes (3) eliminate waste products through the urethra (2) produce mature gametes (4) express secondary sex characteristics 29. Which two processes are included in the prenatal development of a single human embryo? (1) gastrulation and differentiation (2) menopause and cleavage (3) puberty and gastrulation (4) menstruation and fertilization 30. In humans, gestation normally occurs while a developing organism is in the (1) vagina (3) uterus (2) ovary (4) follicle Page 4
