• epididymis

Answer 1

After ovulation, in a female mammal, the structure which is formed by the ruptured follicle is corpus luteum.

Explanation:

After ovulation in a female mammal, the ruptured follicle transforms into a structure called the corpus luteum. This corpus luteum secretes hormones like estrogen and progesterone, which prepare the reproductive organs for pregnancy and stimulate the endometrium to become soft, moist, and thick. If pregnancy does not occur, the corpus luteum degenerates, leading to a decline in these hormone levels and the onset of menstruation. Thus, the structure formed by the ruptured follicle after ovulation is the corpus luteum.
