Answer:
Pluto
Explanation:
Orcus is a plutino, a trans-Neptunian object that is locked in a 2:3 resonance with the ice giant Neptune, making two revolutions around the sun to every three of Neptunes. This is much as pluto, except that the phase of Orcus's orbit is opposite from Pluto's: Orcus is at aphelion when pluto is at aphelion when Pluto is at perihelion and vice versa. This was a major consideration in selecting its name, as deity Orcus was the Etruscan equivalent of the Roman Pluto, and later becamean alternate name for Pluto

Answer:
The endometrial lining is shed during menstruation and is then regenerated by the hormone estrogen.
Explanation:
The menstrual cycle can be described in terms of:
1. <u>OVARIAN cycle</u>: divided into
-Follicular phase of variable length lasting between 7 and 21 days.
-Ovulation
-Luteal phase which is fairly constant and lasts between 12 and 16 days.
The most common cycle length is 28 days and this occurs in 15% of women in their reproductive age
.
The duration of flow is between 2-6 days.
2. <u>ENDOMETRIAL cycle</u>: divided into
-Proliferative phase where there is increase in growth of the functional layer and the endometrial glands under the influence of oestrogen.
-Secretory phase where endometrial changes are influenced by progesterone activity.
The endometrium is made up of the basal layer and the functional layer.
The basal layer remains intact throughout the cycle while the functional layer is shed during each menstruation.
