Graph Analysis
Dear students,
A sample answer to the question in the test about anlayzing a graph. Make sure to review it and improve your analytical skill.
Graph Analysis: Changes in Hormone Levels during the Menstrual Cycle
Hormone levels in blood vs. days
1. Estrogen:
During stage A (day1-day 6): from day 1 till day 6, estrogen levels in blood are relatively low and constant. At day 7 a sharp increase in estrogen blood levels.
During stage B (day 7-day 13): At day 11 estrogen blood levels peek (reaching highest amount) and start to gradually decline from day 12 till day14
Stage C (day14): At day 14 estrogen levels start to increase slightly and consistently until day 24 reaching a second but lower peek.
Stage D (day 15-28): after the 24th day a slight decrease in estrogen level until day 28th but still above initial levels.
2. Progesterone:
During stage A (day1-day 6): Very low levels of progesterone in this stage
During stage B (day 7-day 13): Progesterone levels start to increase slightly at day 13.
Stage C (day14): At day 15 a sharp increase in progesterone levels reaching its peek at day 23
Stage D (day 15-28): A rapid decline from day 24 till day 28 reaching initial levels of progesterone hormone in the blood as day 1.
