Answer 1

The correct option is A (1)- 28 days, (2)- puberty, (3)- menarche, (4)- 45-50 years, (5)- menopause, (6)- 13${}^{th}$ or 14${}^{th}$ days, (7)- ovulation, (8)- progesterone, (9)- fallopian tube

The menstrual cycle is the cycle of natural changes that occurs in the uterus and ovary as an essential part of making sexual reproduction possible. The length of it is an average of 28 days. So, blank 1 is 28 days.
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction, It leads to the beginning of menstrual cycles in women. So, blank 2 is the menstrual cycle.
Menarche is the first menstrual cycle in females. So, blank 3 is menarche.
This cycle begins generally at the age of 12-13 and ends at the age of 45-55. So, option 4 is 45-50.
Menopause marks the end of menstrual cycle. So, blank 5 is menopause.
At around mid-cycle, when the egg is mature, it gets released from the ovary, pushed down to fallopian tube and is available to be fertilized in the process called ovulation. This occurs around 13th-14th day. So, blank 6 is 13${}^{th}$ or 14${}^{th}$ day and blank 7 is ovulation.
Progesterone is an endogenous steroid hormone and is secreted in the ovaries by the corpus luteum. So, blank 8 is progesterone.
After being released from the ovary, the egg is swept into the fallopian tube by the fimbria, which is a fringe of tissue at the end of each fallopian tube. So, blank 9 is fallopian tube
Thus, the correct answer is option (A), '(1) 28 days, (2) puberty, (3) menarche, (4) 45-50 years, (5) menopause, (6) 13th or 14th days, (7) ovulation, (8) progesterone, (9) fallopian tube'.
