Answer 1

1. b

2. a

Answer 2

1) B..As its name suggests, the adrenal medulla is at the center of the adrenal gland surrounded by the adrenal cortex. The adrenal medulla is the body's main source of the catecholamine hormones adrenaline (epinephrine) and noradrenaline (norepinephrine). .


2) B....Ovulation:
The pituitary gland releases a heavy surge of LH. Home ovulation kits are designed to detect this sharp increase. 24 to 36 hours after the surge, the follicle will rupture, releasing the matured egg to the fallopian tube. The remainder of the ruptured follicle (called the corpus luteum) recedes back to the ovary and begins to secrete progesterone. Progesterone causes an increase in blood vessels to the uterine lining, inhibits other eggs from developing, and causes the Basal Body Temperature (BBT) to rise about half a degree.
