Answer:
Solution:
The longest phase of menstrual cycle is luteal phase (around 13 - 14 days) while the shortest phase is ovulatory phase (around 1 day). The formation of haploid second polar body occurs just after ovulation within the fallopian tube once the sperm touches the ocum. Permanent cessation of menses is menopause. In preganancy menses stops temporarily and is regained after delivery of the child. Blastulation occurs within 4-5 days after fertilization. Fertilization aoccurs within two days after ovulation. So blastulation occurs within 7 days from ovulation when the uterus is still in the luteal phase
