Question

the two synthetic hormones used in oral contraceptives are:
a. estrogen and progesterone.

b. testosterone and androgen.

c. insulin and glucagon.

d. fsh and lh.

Explanation:

Oral contraceptives typically use synthetic forms of estrogen and progesterone. These hormones work together to inhibit ovulation, thicken cervical mucus, and alter the uterine lining to prevent pregnancy. Estrogen and progesterone are female sex hormones, and their synthetic versions in contraceptives mimic natural hormonal changes to prevent conception. Option A lists these two hormones. Option B has testosterone (male sex hormone) and androgen (a type of hormone, often male - related), which are not used in oral contraceptives. Option C has insulin (regulates blood sugar) and glucagon (also blood - sugar related), which are not contraceptive hormones. Option D has FSH (follicle - stimulating hormone) and LH (luteinizing hormone), which are involved in the menstrual cycle but are not the main hormones in oral contraceptives.

Answer:

A. estrogen and progesterone.
