The lives of upper class women in Ancient Rome (about 753 BC to 500 AD) mainly centered on running their households and raising the children. Roman women were not allowed to own property or control their own finances — all family inheritances and dowries were transferred to the husband when a woman married. Nor could women participate in politics — they could neither vote nor run for political office. Women's decision-making power was strictly limited to the management of the home. Of course, women who were of the lower social classes — slaves, freedwomen, and prostitutes — had even fewer rights, and lived lives mostly filled with back-breaking labor.

Tissue has a free surface, which faces either a body fluid or the outside environment and thus provides a covering or a lining for some part of the body. The cells are compactly packed with little intercellular matrix.
-
There are two types of epithelial tissues namely simple epithelium and compound epithelium, Simple epithelium is composed of a single layer of cells and functions as a lining for body cavities, ducts, and tubes. The compound epithelium consists of two or more cell layers and has protective function as it does in our skin.
-
On the basis of structural modification of the cells, simple epithelium is further divided into three types. These are
(i) Squamous, (ii) Cuboidal, (iii) Columnar.
<pre> </pre>-
The squamous epithelium is made of a single thin layer of flattened cells with irregular boundaries. They are found in the walls of blood vessels and air sacs of lungs and are involved in a functions like forming a diffusion boundary.
-
The cuboidal epithelium is composed of a single layer of cube-like cells. This is commonly found in ducts of glands and tubular parts of nephrons in kidneys and its main functions are secretion and absorption. The epithelium of proximal convoluted tubule (PCT) of nephron in the kidney has microvilli.
-
The columnar epithelium is composed of a single layer of tall and slender cells. Their nuclei are located at the base. Free surface may have microvilli. They are found in the lining of stomach and intestine and help in secretion and absorption. If the columnar or cuboidal cells bear cilia on their free surface they are called ciliated epithelium. Their function is to move particles or mucus in a specific direction over the epithelium. They are mainly present in the inner surface of hollow organs like bronchioles and fallopian tubes.
-
Some of the columnar or cuboidal cells get specialised for secretion and are called glandular' epithelium. They are mainly of two types: unicellular, consisting of isolated glandular cells (goblet cells of the alimentary canal), and multicellular, consisting of cluster of cells (salivary gland).
-
Compound epithelium is made of more than one layer (multi-layered) of cells and thus has a limited role in secretion and absorption. Their main function is to provide protection against chemical and mechanical stresses. They cover the dry surface of the skin, the moist surface of buccal cavity, pharynx, inner lining of ducts of salivary glands and of pancreatic ducts.

Dimensional formula of Force F [M1 L1 T-2]
So a =1, b=1, c=-2
Now because Newton is in m.k.s system,We Have.
M1 = 1kg, L1 = 1m, T1 = 1s
M2 = 1g, L2 = 1cm, T2 = 1s
n1= 1 Newton
n2 = ?
Using the formula
n2= n1[M1/M2]a [L1/L2]b [T1/T2]c
n2= 1 [1kg/1g]1 [1m/1cm]1 [1s/1s]-2
n2= 1[1000g/1g]1 [100cm/1cm]1 x1
n2= 1000×100 = 100000
= 105 dyne
