- INSTRUCTIONS: ESSAY (Write in your own words no longer than 350 words) Seed germination may depend on the presence or absence of several external and internal factors. Discuss one external and one internal factor that may influence the successful germination of seeds.Direction: Explain the following in paragraph form consists of at least five sentences for each question. Compared to separate sexes and assuming self-fertilizing is not possible, what might be one advantage and one disadvantage to hermaphroditism?Help please? The Topic is sexual reproduction and its physiology. Scenario: During the ovarian cycle, estrogen secretion by the dominant follicle eventually gets so high that it triggers the hypothalamus to produce and secrete even more gonadotropin-releasing hormone (GnRH). This release of GnRH into the anterior pituitary typically causes the anterior pituitary to release a large amount of luteinizing hormone and a much smaller amount of follicle-stimulating hormone. However, Tiffany K. produces a ton of follicle-stimulating hormone and luteinizing hormone during the end of her follicular phase. She had a bad experience with medical doctors in the past, and so she her medical doctor to figure out what is going on. She asks you if you had any suggestions about what hormone the doctor should test first. You tell Tiffany it would make sense for the doctors to first check her levels of...(see image)
