Why do trade winds and westerlies behave differently in the northern and southern hemisphere

coriolis effect

Explanation: because earth rotates as the air is moving, the winds in the northern hemisphere curve to the right and air in the southern hemisphere curves to the left.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
