The endometrium’s condition is a key factor in successful implantation and pregnancy.
In human females, the endometrium of uterus consists of Glandular layer.
(A) Smooth muscle - Incorrect: This describes the myometrium, not endometrium.
(B) Glandular layer - Correct: Endometrium contains uterine glands and stromal tissue for implantation.
(C) Adipose layer - Incorrect: Fat tissue is not a component of endometrium.
(D) Cartilaginous layer - Incorrect: The uterus lacks cartilage in any layer.
The correct answer is (B) Glandular layer, as the endometrium's functional layer contains secretory glands.
The endometrium is the inner lining of the uterus, consisting of two layers:
The functional (glandular) layer, which is where the embryo implants during pregnancy and is shed during menstruation.
The basal layer, which regenerates the functional layer after menstruation.
The smooth muscle, adipose tissue, and cartilaginous layer are not part of the endometrium.
Option (B) is correct because the endometrium consists of the glandular layer.
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
