Neco 2025 Biology Question 36
Practice objective / multiple choice question 36 from the 2025 Neco Biology examination.
In a 28‑day menstrual cycle, estrogen concentration rises linearly from 80 pg/mL on day 8 to a peak of 350 pg/mL on the day just before the luteinising hormone (LH) surge. The LH surge occurs exactly 24 h after the estrogen peak and triggers ovulation on the same day as the surge. If the follicular phase (from day 1 to ovulation) lasts 14 days, on which day does the estrogen peak occur?
