In unicellular organisms, the cell is capable of performing the different life processes with the help of the different cellular organelles. The division of labour in multicellular organisms refers to the presence of different organ systems that are incharge of taking care of a particular life process. For example, the respiratory system, helps the body in obtaining oxygen from the air and supplying it to the rest of the body.

The intermolecular forces of attraction that are present in solids are very strong.  The constituent particles of solids have fixed positions i.e., they are rigid. Hence, solids have a definite volume.

Given,

Dimensions of the tank = 

4000 people requiring 150 litres of water per head per day

The total volume of water required = 

Let the number of days the water will last be 

We know,

The volume of a cuboid = 

 The volume of the water tank = 

According to question,

Therefore, the water in the tank will last for 3 days.

manuscrits

Manuscripts: They are the records written by hand. These were usually written on palm leaf, or on the specially prepared bark of a tree known as the birch

Manuscrits: Ce sont les documents écrits à la main. Ceux-ci étaient généralement écrits sur une feuille de palmier ou sur l'écorce spécialement préparée d'un arbre connu sous le nom de bouleau

Pythagoras theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say a, b and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple.

Consider the triangle

Where “a” is the perpendicular side,

“b” is the base,

“c” is the hypotenuse side.

According to the definition, the Pythagoras Theorem formula is given as:

i) Temperature - The dark reactions of photosynthesis are enzymatic and hence temperature controlled. Though the light reactions are also temperature sensitive, they are affected to a much lesser extent. The C₄ plants respond to higher temperatures and show higher rate of photosynthesis while C₃ plants have a much lower temperature optimum.

The temperature optimum for photosynthesis of different plants also depends on the habitat that they are adapted to. Tropical plants have a higher temperature optimum than the plants adapted to temperate climates.

ii) Water - The effect of water as a factor is more through its effect on the plant, rather than directly on photosynthesis. Water stress causes stomata to close hence reducing CO₂ availability. Besides, water stress also makes leaves wilt, thus reducing the surface area of the leaves and their metabolic activity as well.

iii) CO₂ - CO2 is a vital raw material needed for photosynthesis.Increased amount of CO2 will increase the rate of photosynthesis to a certain limit, after which a further increase in its amount will no longer increase the rate any further. This is when the other factors necessary for photosynthesis, such as light, become "limiting reactants"; that is, those other factors also need to increase to bring about a further increase in the rate.

The process of deriving large crystals of pure substances from their solutions is known as crystallisation. It is a physical change. Crystals of salt are obtained by the evaporation of sea water.

Similarly crystals of copper sulphate can be obtained by adding copper sulphate powder to the boiling solution of water and dilute sulphuric acid. This mixture when filtered and allowed to cool produces crystals of copper sulphate.

तुलसी दास हिंदी के श्रेष्ठतम भक्त कवियों में से एक है जिन्होंने गंभीरतम दार्शनिक काव्य लिखने के साथ-साथ व्यंग्य का अनूठा सौंदर्य भी प्रस्तुत किया है। इस प्रसंग में लक्ष्मण ने मुनि परशुराम की करनी और कथनी पर कटाक्ष करते हुए व्यंग्य की सहज-सुंदर अभिव्यक्ति की है। लक्ष्मण ने शिवजी के धनुष को धनुही कह कर परशुराम के अहं को चुनौती दी थी। उन्होंने व्यंग्य भरी वाणी में कहा था-

(i) बिहसि लखनु बोले मृदु बानी। अहो मुनीसु महाभट मानी।
पुनि पुनि मोहि देखाव कुठारु। चहत उड़ावन फूँकि पहारू।।

(ii) इहां कुम्हड़बतिया कोउ नाहीं। जे तरजनी देखि मारि जाहीं।।
देखि कुठारु सरासन बाना। मैं कछु कहा सहित अभिमाना।।

लक्ष्मण ने व्यंग्य करते हुए परशुराम से कहा था कि उन्हें जो चाहे कह देना चाहिए। क्रोध रोक कर असहय दुःख नहीं सहना चाहिए। परशुराम तो मानो काल को हाँक लगा कर बार-बार बुलाते थे। भला इस संसार में कौन ऐसा था जा उनके शील को नहीं जानता था। वे तो संसार में प्रसिद थे। वे अपने माता-पिता के ऋण से मुक्ता हो चुके थे तो उन्हें अपने गुरु के ऋण से भी मुक्त हो जाना चाहिए था।

सो जनु हमरेहि माथें काढ़ा। दिन चलि गये ब्याज बड़ बाढ़ा।
अब आनिअ ब्यवहरिआ बोली। तुरत देउँ मैं थैली खोली।।

वास्तव मे लक्ष्मण ने परशुराम के स्वभाव और उनके कथन के ढंग पर व्यंग्य कर अनूठे सौंदर्य की प्रस्तुति की ।

Jan 30, 1948   : He was shot dead by Nathuram Godse at Birla House.
 

Answer:
 

Mahatma Gandhi was born on Oct 2, 1869, to Karamchand and Putlibai at Porbandar. After completing his studies in England, he went to South Africa. When he suffered discrimination, he started civil disobedience for civil rights of the Indian community. Around 1915, he came back to India. He started Satyagraha, civil disobedience, fasts, marches, movements and was sentenced many times. His efforts helped India gain freedom from the British. In 1948, a mad man named Nathuram Godse assassinated him outside Birla House.

• Increase in Agricultural Production: Foodgrains in India saw a great rise in output. It was a remarkable increase. The biggest beneficiary of the plan was the Wheat Grain. The production of wheat increased to 55 million tonnes in 1990 from just 11 million tonnes in 1960.
• Increase in per Acre Yield: Not only did the Green Revolution increase the total agricultural output, it also increased the per hectare yield. In case of wheat, the per hectare yield increased from 850 kg/hectare to an incredible 2281 kg/hectare by 1990.
• Less Dependence on Imports: After the green revolution, India was finally on its way to self-sufficiency. There was now enough production for the population and to build a stock in case of emergencies. We did not need to import grains or depend on other countries for our food supply. In fact, India was able to start exporting its agricultural produce.
• Employment: It was feared that commercial farming would leave a lot of the labour force jobless. But on the other hand, we saw a rise in rural employment. This is because the supporting industries created employment opportunities. Irrigation, transportation, food processing, marketing all created new jobs for the workforce.
• A Benefit to the Farmers: The Green Revolution majorly benefited the farmers. Their income saw a significant raise. Not only were they surviving, they were prospering. It enabled them to shift to commercial farming from only sustenance farming.

Franz was a student in one of the schools in the districts of Alsace. Having a poor family set up, the boy was often asked to work in some mill for earning some money. But the family could not pay due attention towards his education, so the boy loved outside environment and wanted to enjoy it. In the school too, he often loved to work in the garden. He became fond of shirking from work and used to put off his learning as well as home task. But he was much scared of his teacher M. Hamel.

In addition to this, the boy had an acute sense of understanding, feeling, recognition and respect. Entering the school, he sensed unusualness and calmness there. He was much surprised at this and was rather troubled to know that his teacher was leaving them because of an order from Berlin had banned the teaching of French. During the writing period, he noticed sad expressions over the face of M. Hamel. When the teacher taught a lesson in grammar, it left an indelible impression on the boy. He felt that the teacher was going to pour everything in their minds. Then the teacher wrote on the blackboard ‘Long Live France’. The boy was deeply moved and he recognised his teacher for his worth. Thus Franz had all the senses of head and heart.

An electromagnetic field is referred as a physical field of objects that are electrically charged. It is one among the four fundamental forces of nature, other includes strong interaction, weak interaction, and gravitation.

The electromagnetic field affects the change in the behaviour of charged objects surrounding a particular place. It extends indefinitely throughout space and known as electromagnetic interactions.

In the beginning, M. Hamel emerges as a very strict teacher who always keeps a ruler in his hand. Apparently, it appears that M. Hamel does not understand the tender feelings of his students. He seems to be a typically hard task-master. But when he teaches his last lesson, the sensitive and thought-provoking teacher within him comes out. He is a great patriot and wants his students and countrymen to be proud of their nation and language. He exhorts them to come forward and to keep their language and culture intact and alive. M. Hamel is a very patient fellow. He teaches even his last lesson with great patience. To sum up, M. Hamel is a perfect teacher.

शुरू में, M. Hamel एक ऐसे कठोर अध्यापक के रूप में उभरकर आते हैं जो हमेशा अपने हाथ में एक डण्डा रखता है। सतही तौर पर ऐसा लगता है कि M. Hamel अपने छात्रों की सुकोमल भावनाओं को नहीं समझते हैं। वह विशिष्ट सख्त मिजाज व्यक्ति प्रतीत होते हैं। किन्तु जब वह अपना अन्तिम पाठ पढ़ाते हैं, तो उनके अन्दर का संवेदनशील और विचारोत्तेजक अध्यापक बाहर आ जाता है। वह एक महान देशभक्त हैं और चाहते हैं कि उनके विद्यार्थी तथा देशवासी अपने देश और अपनी भाषा के प्रति गौरव का अनुभव करें। वह उनका आह्वान करते हैं कि वे आगे आएं और अपनी भाषा तथा संस्कृति को सुरक्षित व जीवित रखें। M. Hamel एक बहुत ही धैर्यशाली व्यक्ति हैं। वह अपने अन्तिम पाठ को बहुत धैर्य के साथ पढ़ाते हैं। संक्षेप में, M. Hamel एक सम्पूर्ण शिक्षक हैं।

A biography, or simply bio, is a detailed description of a person's life. It involves more than just the basic facts like education, work, relationships, and death; it portrays a person's experience of these life events.

Lysosomes can be termed as waste disposal system of the cell. For almost all type of organic materials they contain digestive enzymes.  For example, when cell gets damaged, lysosome may burst and the enzymes digest their own cell. Therefore lysosomes are known as the Suicidal bags of a cell or we can say that they posses different kind of hydrolases on release of these enzymes that cause death of cell.
