1.
The equation of the tangent line to the curve y = x3 at the point (1, 1) is:
y = 3x - 2
y = 3x + 1
y = -3x + 4
y = x
2.
If the tangent to y = x2 - 4x + 5 is parallel to the x-axis, the point of tangency is:
(2, 1)
(4, 5)
(0, 5)
(2, 0)
3.
The decomposition of the corpus luteum in the ovary of a non-pregnant woman at the end of the menstrual cycle results in:
Placenta formation
Continued growth of the uterine lining
A sharp drop in the concentration of the hormone progesterone leads to the breakdown of the uterine lining, the rupture of its capillaries, and the occurrence of menstruation
Secretion of huge amounts of LH
4.
The outer embryonic membrane that surrounds the uterine membrane and from which digital villi emerge, which are immersed in the uterine lining to form the placenta, is:
Sagging membrane
Corpus luteum
umbilical cord
Amniotic membrane (Chorion)
