  1. Epithelial Tissue:

It is the simplest tissue and protective in nature. The cells of this tissue are tightly packed and they form a continuous sheet. They contain a very little or no intercellular space. It covers most organs and cavities within the body. The skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules are all made of epithelial tissue. Anything entering or leaving the body crosses at least one layer of epithelium. As a result, the permeability of the cells of various epithelia plays an important role in regulating the exchange of materials between the body and the external environment and also between different parts of the body. All the epithelium is usually separated from the underlying tissue by an extracellular fibrous basement membrane.

 

 

Epithelium type

Characteristics

Shape of cells

Function

Squamous

It is made up of thin, flat and irregular-shaped cells. It forms the delicate lining of cavities (mouth, oesophagus, nose, etc.) and blood vessels.

 

 

It protects the underlying parts of body from mechanical injury, entry of germs, chemicals and drying.

 

Cuboidal

It consists of cube-like cells. These are found in kidney tubules, thyroid vesicles and in glands.

 

It helps in absorption, secretion and excretion. It also provides mechanical support.

Columnar

It consists of cells which are taller than broader i.e. pillar-like. It forms the lining of stomach, small intestine and colon.

 

Its main function includes absorption and secretion.

Ciliated

They are cubical or columnar cells with cilia. These are found in sperm ducts and line the trachea, bronchi, kidney tubules and oviducts.

 

The rhythmic, concerted beating of the cilia moves solid particles in one direction through the ducts.

Glandular

The columnar epithelium is modified to form glands which secrete chemicals.

 

Its main function is secretion.

Shahid as a Great Poet and Music Lover

Agha Shahid Ali was a profound lover of good poetry and music. He was a great poet and always enjoyed the company of poets and writers. He was strongly influenced by James Merril, who changed the direction of his poetry radically.

Shahid loved music, too. He enjoyed doing tasks against the background of songs and voices. Even the doorbell ring had a musical sound. His mother was also a famous singer from Gazal whom he remembered a lot. Through his poems, his melodious words and his amazing sentences, he gave him freedom to live and gladly shook his hands with death.

Knowing that he would die at any time, Shahid Ali opened his treasure trove of enormous strength of life and tied Ghosh to the ropes of nostalgia. He was also very strong in repartee. This sheer dynamism was his way of life until ” the last saffron of the Shahid world ” was gone.

Shahid was a Wonderful Repartee

Repartee means the person who is quick and amusing in a conversation with answers and remarks. Once at the airport in Barcelona, a woman security guard stopped Shahid for a security check. She asked what he did for Shahid. Shahid said he was a poet. And the woman asked him what he did in Spain. Shahid said he was doing poetry. The woman was very irritated. She asked Shahid in anger if he carried anything that could be dangerous for the passengers. Shahid clapped his hand uniquely at his chest and shouted: “Only my heart.”

Shahid’s Love For His Homeland

The love of Shahid for Kashmir is shown in most of his works such as ” The Country without a Post Office, ” ” Eleven Stars in Andalusia, ” etc. He sees Kashmir as a possible ” flashpoint of a nuclear war ” and warns in ” Ghalib ‘s Ghazal ” that ” terraced cities ” and ” marble palaces ” can be reduced to a ” wild ” if peace in Kashmir is not achieved. Ali talks about exiles in ” Eleven Stars in Andalusia ” not only in Kashmir, but also in Spain and Palestine.

Shahid loved his homeland even in the last stage of his life. He wanted Kashmir to come back and die here. To quote his own words, he said, ” I want to return to Kashmir to die. ” His words revealed the warmth of the political lava during his stay in Kashmir. During this short period of their friendship, Shahid left an unambiguously different Kashmir with some fabulous brush strokes.

Shahid Was a Secular Person

Even being a firm believer in the separation of politics and religious practice, he set apart the separatism, atrocities, and violence that had already led the paradise to a paradise lost. At the point when his childhood loitered about in the room of Srinagar, he intensely set a craving of wants to his parents. It was but to build up a little Hindu sanctuary inside his room.

He was mainstream and comprehensive even at the season of his remaining on the consuming map book of Kashmir.His mother conveyed icons and different trappings to her home and the deepest piece of their home turned into the holiest place a temple. Along these lines, his home turned into a delightful religious blend of Hinduism and Islam. He vision tended always the comprehensive and ecumenical.

Shahid’s Love For Food and Festivity

Shahid was food and celebration manaic. His ability in the kitchen was unbelievable. He would spend days planning and arranging a supper party. He thought I wouldn’t give him any chance to be discouraged. He loved the Kashmiri wazwon a lot, especially the rogan josh.

Despite his last phase of illness with all affirming his death, Shahid could appreciate food and talk about food. He went to it without disappointment at whenever there was a meeting. Whether it was to satisfy his aspiration or to satisfy his friends, we have no foggy idea. All things considered he always appeared as as insane person of food and festivity appeared.

Nucleus contains positive charged protons. The force of attraction of between positive charge nucleus and negative charged electrons present in outermost shell is callednuclear charge/ force. If inner extra electrons/ orbitals are present between nucleus and valence electrons, then the nuclear charge is calledeffective nuclear chargeor nuclear pull. With increase in protons, positive charge increases hence, hence nuclear charge increases

Nancy Rajput 6 years, 11 months ago

The effective nuclear charge is the net charge an electron experiences in an atom with multiple electrons. Higher energy electrons can have other lower energy electrons between the electron and the nucleus, effectively lowering the positive charge experienced by the high energy electron.

Suppose if we have a parent chain and a CH3 group attached to it then we name it as methyl....but when double bond is not taken in parent chain then that CH3 is changed to CH2 then we call it as "methyledene" or" Methylene "...........or if u dont understand so suppose a parent chain started with a double bond and ended with a double bond and also a carbon is combined to it with double bond ( =CH2 with parent chain) . This is an alklidene group we name its member as 1. Methyledene, ethyledene etc.

Amount of energy required to 1 mole of ion with water

Yakshi ? 6 years, 11 months ago

Thanks .....

Ankit Singh 6 years, 11 months ago

The heat energy released when new bonds are made between the ions and water molecules is known as the hydration enthalpy of the ion. The hydration enthalpy is the enthalpy change when 1 mole of gaseous ions dissolve in sufficient water to give an infinitely dilute solution. Hydration enthalpies are always negative. Hope this will help u yakshi ?

Ʌɐpɐʎ Ɐuɐɥsɹɐp . 6 years, 11 months ago

Well it the amount of energy released when 1mole of gaseous ions combine with water to form hydrated ions...the hydration enthalpies of alkaline earth metal ions are larger than those of alkali earth metal ion.. ✌️

Nancy Rajput 6 years, 11 months ago

The change in enthalpy (the amount of heat released) when one mole of gaseous ions form hydrated ions under standard conditions is called hydration enthalpy.
