Osmosis

Osmosis is diffusion of water molecules across the plasma membrane from a region of its higher concentration to a region of its lower concentration. This can be proved by an experiment.

Consider a U shaped tube with side A filled with pure water and side B with same quantity of sucrose solution (sugar dissolved in water) separated by a membrane permeable to water and impermeable to sugar. Since membrane is 


permeable to water molecules, it can move from side "A" to "B" and from "B" to "A". At side "A" there are only water molecules whereas at side "B" the presence of sucrose molecules means concentration of water molecules is  less than at side "A". Thus in unit time more water molecules will diffuse from side "A" to "B" than from "B" to "A". In other words there is net movement of water molecules from "A" to "B". As a result, level of sugar solution will begin to rise and that of water will begin to 


U tube divided by a semipermeable membrane. The membrane at the base of the U tube is permeable to water, but not to sugar molecules (black balls). 
Left:       Side A contains only water; side B contains a sugar solution. Initially, the quantity of fluid in the two sides is the same.
Center:    A larger number of water molecules (colored balls) bump into the membrane per unit time on side A than on side B.
Right:      Because more water molecules move from A to B than from B to A, the level of fluid on side A falls white that on side B rises. 

Responsibilities of good citizen.

Good Citizens are those who fulfil their responsibilities. They are loyal and patriotic to their country. They do their duties honestly and selflessly. They do not keep talking about their rights. Instead they busy doing their duties. Good citizen are a model of discipline, They show discipline in everything. It may be talking, walking, eating, sitting, standing, anything. We can not become good citizens without discipline in life. If we follow discipline in life, we can change our fate and our country's fate too.

After completing his education at an early age, Faisal started taking interest in the affairs of the started and helped his father in governing the country. He was made Governor of Hijaz, when he was only twenty. Latter on, he served as Saudi Foreign Minister  visiting several countries of the world where he held important discussions and gained a great deal of experience. He also, had the opportunity of holding the command of the Armed Forces of his country.


After the death of King Abdul Aziz, his eldest son Sa'ud become the King, Faisal was made the Crown Price and Prime Minister in 1958, Saudi Arabia was in serious difficulties at that time. Faisal used his wisdom and intelligence to overcome these difficulties at that time, 






Faisal used at that time his wisdom and intelligence to overcome these difficulties, In 1969, he resigned from the post of the prime Minister, but accepted it again in 1962. His elder brother King Sa'ud fell seriously ill in 1964, and Faisal was chosen as the King by the Council of ministers.

    King Faisal was devoted to Islam. He was a good Muslim and led a simple life. He did his best to see his people live according to the teachings of Islam. He possessed great qualities of leadership and proved to be an able ruler. He loved his people and  ruled the country wisely and justly under his rule, Saudi Arabia made great progress in many fields. He spend a lot of money on the development of his country. The main source of income for Saudi Arabia is mineral oil, and he made every effort to increase its production new factories and mills were set up in Saudi Arabia. and industry made great progressed. Vest areas of the desert were irrigate and new lands were brought under cultivation.

NURSING

Nursing means taking care of and looking after the sick, the injured, the young old or the helpless, with love and sympathy. It is difficult to say at what point in history nursing was organised in a scientific way. Yet it is easy to understand that it must be as old as man's feeling for his suffering fellow men. For only sympathy and love could move one human being to feel sorry for someone in distress, to look after him in sickness and try to do someone for him and to restore him to health.

Islam regards nursing very important. Our Holy Prophet (peace be upon him) visited the sick regularly, comforted them and spoke kind words to them. He would go, even to inquire after his ailing enemies. He urgent the Muslims to help those who were sick or suffering. On the battlefield, all Muslim soldiers were always very kind to the sick, old and the injured. They never killed their wounded enemies. Muslim ladies were very active on the battlefield giving water to the soldiers and tending the wounded and the sick.  

Nursing was not at all popular in the beginning. Parents did not allow their daughter to become nurse. This can perhaps be best shown in the story of the girl, who in 1851,became the founder women in history. Her name was Florence Nightingale. Florence Nightingale was born in the town of Florence in Italy in 1820. 

Anatomy of the Heart

Your heart is located under your ribcage in the center of your 

chest between your right and left lungs. Its muscular walls 

beat, or contract, pumping blood to all parts of your body.

The size of your heart can vary depending on your age, size, 

and the condition of your heart. A normal, healthy, adult 

heart usually is the size of an average clenched adult fist. 

Some diseases can cause the heart to enlarge.

The Exterior of the Heart

Below is a picture of the outside of a normal, healthy, human 

heart.

Heart Exterior

In figure B, the heart is the muscle in the lower half of the 

picture. The heart has four chambers. The heart's upper 

chambers, the right and left atria (AY-tree-uh), are shown in 

purple. The heart's lower chambers, the right and left 

ventricles (VEN-trih-kuls), are shown in red.

Some of the main blood vessels (arteries and veins) that 

make up your circulatory system are directly connected to the  

heart.

The Moon is Receding, and the Tides are to Blame

The Moon gets further from the  
Earth by about 4 cm per 

year.

The graphic helps understand 

why:

1. The Moon raises tidal bulges in the Earth’s oceans.

2. As the Earth rotates, friction causes the tidal bulge to be 

pulled in the rotation direction, so that it is not directly under 

the Moon.

3. The water in the bulge exerts a small gravity force on the 

Moon. Because of the bulge’s offset, part of this force is to 

the left, and this causes the Moon to speed up slightly.

4. As it speeds up, the size of its orbit increases.

Distance measurements using lasers are so precise that the 

increase in orbit size has been verified. In a few hundred 

million years, the Moon will be far enough away that it can no 
longer cover the Sun, and there will be no more total solar 

eclipses.

The same phenomenon causes the Earth’s rotation rate to 

slow down. The total Earth-Moon angular momentum must 

remain constant, and as the Earth imparts angular 

momentum to the Moon, the Earth’s angular momentum (and 

rotation rate) must decrease.

what is science?

Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts (data). An ultimate purpose of science is to discern the order that exists between and among est the various facts.

Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that under standing It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions. (There are, of course,

QUAID E AZAM MUHAMMAD ALI JINNAH

                                         

OUR NATIONAL HERO

• Quaid-e-Azam Muhammad Ali Jinnah, the founder of Pakistan, is our national hero. His name will be remembered with great honor in the history of mankind. He fought' sincerely and selflessly the battle of freedom for the Muslims and won in the long run.
• Our Quaid-e-Azam, which means the great leader, was born in Karachi on the 25th of December, 1875. During his childhood he used to work excessively hard and showed his qualities as a talented child After completing his primary and secondary education in the Sindh Madrasa-tul-Islam, Karachi, he was sent to England for higher studies
• Azam, as his nature was, could not lag behind in this sacred task and soon by his persistent devotion to duty, sincerity and enthusiasm came to the front row of the freedom fighters. In the beginning he joined the Indian National Congress and believed that Muslims and Hindus should join' hands to free their motherland from the British rulers. He also believed that Hindus and Muslims should live peacefully as members of one nation. But, later on, he changed his standpoint in view of the ,activities of the Hindus which were becoming increasingly detrimental to the cause of the' Muslims. The one-nation theory was also given up and he began to think that the Muslims are different from the Hindus in every respect and therefore he propounded the two-nation theory in India and supported vehemently the idea of a separate Independent Muslim State.
• For this he joined the Muslim League--a political organization representing all the Muslims of India. In the year 1933 he was elected the President of all India Muslim League, That office he held till Pakistan came into being. It was under his president ship that the all India Muslim League passed the famous Pakistan Resolution in the historic annual session held in the Minto Park, Lahore in the year 1940. In this Resolution the Muslims resolved to get the British India divided and to have a separate Muslim state termed as Pakistan.
• He succeeded in the long run and the whole world was surprised to see that Pakistan became a reality on the 14th August 1947 when our Quaid-e-Azam took over as her first Governor General and Khan Liaqat Ali Khan as her first Prime Minister. Quaid-e-Azam did not take rest afterwards. He worked hard than ever for the consolidation of Pakistan, our dear home-land. The British rulers left for good, leaving deceitfully a large number of problems for our country. Quaid-e-Azam continued his efforts to surmount the problems and difficulties. But his health failed, it was already fast deteriorating, and he breathed his last on the 11th September, 1948, just one year after independence. He was laid to rest in Karachi, the place where he was born and where he became the first Governor General of Pakistan.

THE WISE CALIPH

The caliph Haroon - Rasheed was known and respected for his justice and wisdom.At night He would disguises  himself as a common man and go through.the streets of Baghdad. He would mingle with the common people in order to gain first-hand knowledge of their difficulties and problem.

One day, when he was holding court, two men men were brought before him. One of them was well-dressed and appeared to be a well-to-do, respectable citizen, while the other seemed to be a beggar, because he was in rags. these two men were holding between them a beautiful white horse. The Qazi approaches the Caliph and said to him: " O Leader of the Faithful! I've brought before you a dispute which I could not settle. It is a difficult case, but I am certain that with your knowledge and wisdom. you will pronounce a just decision.

        "What is the dispute?" asked the Caliph.

       "These two men here are fighting over this horse. Each one of them claims "

       " Step forward,"the Caliph ordered the well-dressed man, "and let's here what you've to say."

The man said to the Caliph:  "O Leader of the Faithful! I beg to believe me that whatever I say in your presence shall be the truth. This morning, when I was riding to the city, I saw this beggar limping along ahead of me, on hearing the sound of my horse's hoofs, he turned round and motioned to me to stop. I pulled the reins of my horse. He begged me to give him a ride up to the gate. He was lame, I felt sorry for him. So I pulled him up behind me on the horde. When we reached the city gate, I stopped and turned round to help him get down. He refused to dismount. I was puzzled, and gently told him to get down because we had reached the city gate. He said, "Why should I get down? I gave you a ride and now you want to rob me of my horse?"

        Then the beggar limped forward and said: "O Leader of the Faithful! You are the helper and guardian of the poor. You are a wise and just Caliph, Have pity on me and save me from the injustice of this rich man. I can swear that this horse belongs to me. You must be thinking, like everybody else in this court, how a beggar like me can afford to buy and keep such a fine horse. it is because of this horse that I am rags, Whatever money I had, I spend on this horde. This morning, as I was coming to the city on my horse, I noticed this man walking along the road, When I came close to him he stopped me and requested to lend him my horse, for he was in a great hurry to react the city. Of course, I could not lend my horse to a complete stranger. Could I? Instead, I let him ride my horse, while I sat behind him. As we reached the city gate? he asked me to get down and leave the horse to him. 'Such a fine horse should not belong to a beggar,' he said. 'Now, be off and don't you mention it to any one. And even if you do, nobody is going to believe you. now, I beg you to save me from robber and restore to me what is my own."
