	The menstrual cycle's main function is to regularly replace the lining of the uterus
	A high body temperature indicates ovulation is occurring
	The menstrual cycle is an endocrine cycle regulating reproductive physiological changes

2 Most pregnancies can be detected by pregnancy tests soon after fertilization.

	true
	false

3 Which of the following statements is correct about the zona pellucida:

	surrounds the oocyte in the ovary
