Igcse Model Questions Vol1 2022 Biology Question 26
Practice objective / multiple choice question 26 from the 2022 Igcse Model Questions Vol1 Biology examination.
In a study, the concentration of estrogen in the blood rises by \(0.5\) IU L\(^{-1}\) per day for each mature follicle present. A girl's estrogen level was measured at \(4\) IU L\(^{-1}\) on day 1 of her menstrual cycle and reached the threshold of \(12\) IU L\(^{-1}\) on day 5, when the LH surge occurs. Assuming the increase in estrogen is solely due to the mature follicles and that the number of mature follicles remains constant during days 1‑5, how many mature follicles were present?
