Question

question 1 of 10
the hormone levels during the menstrual cycle are shown below.
what would happen if the hormone levels did not have their peak just before day 14?
a. fertilization would occur.
b. the fertilized egg would not attach to the uterus.
c. menstruation would occur.
d. the egg would not be released into the fallopian tube.

Explanation:

The peak of luteinizing hormone (LH) just before day 14 triggers ovulation, the release of an egg into the fallopian tube. Without this peak, ovulation (egg release) would not occur. Fertilization (A) requires an egg to be present. Menstruation (C) is influenced by later - stage hormone changes (progesterone decline). The fertilized egg attaching to the uterus (B) is related to progesterone levels after ovulation. Since the key event at day 14 is ovulation (egg release) triggered by the LH (and estrogen - related) peak, without it, the egg would not be released.

Answer:

D. The egg would not be released into the fallopian tube.
