Case A biology student after studying about the different levels of hormones during the menstrual
cycle was comparing 2 subjects (Patients). A table was created after looking at the levels of
hormones A and B for Subject 1 and 2. Read the information in the table and answer the
questions that follow (Q49 to 54):
HORMONE A HORMONE B
Subject 1 Shows a peak on the 14th Day
of the menstrual cycle
Falls down during the
luteal phase
Subject 2 Shows a peak on the 14th Day
of the menstrual cycle
Level is maintained high
in the luteal phase
