Final answer:
Day 1 of the menstrual cycle is not when the secondary oocyte is released from its follicle; ovulation occurs around Day 14.
Step-by-step explanation:
The statement 'Day 1 of the menstrual cycle is when the secondary oocyte is released from its follicle' is false. Day 1 of the menstrual cycle is when menstruation starts, and it indicates the shedding of the uterine lining. The release of the secondary oocyte from its follicle typically occurs around Day 14 of the menstrual cycle, during ovulation.
