Practice questions testing deep understanding of gametogenesis, menstrual cycle, and embryonic development.
Q1. In human females, oogenesis is a highly disjointed process compared to spermatogenesis in males. Identify the specific stages at which meiosis is "paused" or arrested during a female's lifetime, and state what event triggers the completion of Meiosis II.
Q2. The placenta is a temporary, highly specialized organ formed during pregnancy. Explain its dual role as both an exchange surface and an endocrine gland. Name two hormones exclusively produced by the placenta.
Q3. Assertion (A): The surge of Luteinizing Hormone (LH) in the middle of the menstrual cycle induces ovulation. Reason (R): LH causes the rapid growth and rupture of the mature Graafian follicle, releasing the secondary oocyte.
