The purpose of your heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries. Oxygen-rich blood is pumped out of the left side of your heart (shown on the right in the diagram) into the arteries to these tissues and organs.
Blood that has delivered its nutrients and oxygen and is in need of oxygen comes back to your heart in the veins and enters the right hand side of the heart. This blood which is in need of oxygen (so-called deoxygenated blood) is sent to your lungs to pick up oxygen and get rid of carbon dioxide.

Answer: In modern days; rulers are chosen through popular vote. But in the janapadas, a ruler was not chosen rather a person was supposed to show his supremacy to become the ruler. To do so, the raja had to perform the ashwadeha yajna so that other rajas in the mahanjanapada would accept his supremacy.

Answer: Dust and Colour particles forms nuclei for condensation of water vapour.
|Explanation:
Certain types and shapes of dust and salt particles, such as sea salts and clay, make the best condensation nuclei. With proper quantities of water vapor and dust in an air parcel, the next step is for the air parcel mass to be cooled to a temperature at which cloud droplets or ice crystals can form.

Chemical reactions can be classified in following types:
- Combination Reaction
- Decomposition Reaction
- Displacement Reaction
- Double Displacement Reaction
- Oxidation and Reduction Reaction
Combination Reaction: Reactions in which two or more reactants combine to form one product are called COMBINATION REACTION.
A general combination reaction can be represented by the chemical equation given here.
<i>A + B ⇨ AB</i>
<hr />Example: When magnesium is burnt in air (oxygen), magnesium oxide is formed. In this reaction, magnesium is combined with oxygen.
<i>Mg + O2 ⇨ 2MgO</i>
<i>Magnesium + Oxygen ⇨ Magnesium oxide</i>
When carbon is burnt in oxygen (air), carbon dioxide is formed. In this reaction, carbon is combined with oxygen.
<i>C + O2 ⇨ CO2</i>
<i>Carbon + Oxygen ⇨ Carbon dioxide</i>
When hydrogen reacts with chlorine, hydrogen chloride is formed.
<i>H2 + Cl2 ⇨ 2HCl</i>
<i>Hydrogen + Chlorine ⇨ Hydrogen chloride</i>
When calcium oxide reacts with water, calcium hydroxide is formed
<i>CaO + H2O ⇨ Ca(OH)2</i>
<i>Calcium oxide + Water ⇨ Calcium hydroxide</i>
When carbon monoxide reacts with oxygen, carbon dioxide is formed.
<i>2CO + O2 ⇨ 2CO2</i>
<i>Carbon monoxide + Oxygen ⇨ Carbon dioxide</i>
<hr />Decomposition Reaction: Reactions in which one compound decomposes in two or more compounds or element are known as DECOMPOSITION REACTION. Decomposition reaction is just opposite of combination reaction.
A general decomposition reaction can be represented as follows:
<i>AB ⇨ A + B</i>
Example: When calcium carbonate is heated, it decomposes into calcium oxide and carbon dioxide
<i>CaCO3 ⇨ CaO + CO2</i>
<i>Calcium carbonate ⇨ Calcium oxide + Carbon dioxide</i>
When ferric hydroxide is heated, it decomposes into ferric oxide and water
<i>2Fe(OH)3 ⇨ Fe2O3 + 3H2O</i>
<i>Ferric hydroxide ⇨ Ferric oxide + Water</i>
When lead nitrate is heated, it decomposes into lead oxide, nitrogen dioxide and oxygen.
<i>2Pb(NO3)2 ⇨ 2PbO + 4NO2 + O2</i>
<i>Lead nitrate ⇨ Lead oxide + Nitrogen oxide + Oxygen</i>
In above examples, compound is decomposed because of heating, so, these reactions are called THERMAL DECOMPOSITION REACTION.

आज के आधुनिक युग में व्यक्ति का जीवन अपने स्वार्थ तक सीमित होकर रह गया है । प्रत्येक कार्य के पीछे स्वार्थ प्रमुख हो गया है । समाज मे अनैतिकता, अराजकता और स्वार्थ से युत) भावनाओं का बोलबाला हो गया है । परिणाम स्वरूप भारतीय संस्कृति और उसका पवित्र तथा नैतिक स्वरूप कुंभला-सा हो गया है ।
इसका एक कारण समाज में फैल रहा भ्रष्टाचार भी है । भ्रष्टाचार के इस विकराल रुप को धारण करने का सबसे बड़ा कारण यही है कि इस अर्थप्रधान युग में प्रत्येक ब्यूक्ति धन प्राप्त करने में लगा हुआ है । कमरतोड महंगाई भी इसका एक प्रमुख कारण है ।
मनुष्य की आवश्यकताएँ बढ जाने के कारण वह उन्हें पूरा करने के लिए मनचाहे तरीकों को अपना रहा है । भारत के अंदर तो भ्रष्टाचार का फैलाव दिन-भर-दिन बढ़ रहा है । किसी भी क्षेत्र में चले जाएं भ्रष्टाचार का फैलाव दिखाई देता है । भारत के सरकारी व गैर-सरकारी विभाग इस बात का सबसे बड़ा प्रमाण हैं ।
आप यहाँ से अपना कोई भी काम करवाना चाहते हैं, बिना रिश्वत खिलाए काम करवाना संभव नहीं है । मंत्री से लेकर संतरी तक को आपको अपनी फाइल बढ़ताने के लिए पैसे का उपहार चढाना ही पड़ेगा । स्कूल व कॉलेज भी इस भ्रष्टाचार से अछूते नहीं है । बस इनके तरीके दूसरे हैं ।
गरीब परीवारों के बच्चों के लिए तो शिक्षा कॉलेजों तक सीमित होकर रह गई है । नामी स्कूलों में दाखिला कराना हो तो डोनेशन के नाम पर मोटी रकम मांगी जाती है। बैंक जो की हर देश की अर्थव्यवस्था का आधार स्तंभ है वे भी भ्रष्टाचार के इस रोग से पीडित हैं ।
आप किसी प्रकार के लोन के लिए आवेदन करें पर बिना किसी परेशानी के फाइल निकल जाए यह तो संभव नहीं हो सकता । देश की आंतरिक सुरक्षा का भार हमारे पुलिस विभाग पर होता परन्तु आए दिन यह समाचार आते-रहते हैं की आमुक पूलिस अफसर ने रिश्वत लेकर एक गुनाहगार को छोड़ दिया । भारत को यह भ्रष्टाचार खोखला बना रहा है ।
हमें हमारे समाज में फन फैला रहे इस विकराल नाग को मारना होगा । सबसे पहले आवश्यक है प्रत्येक व्यक्ति के मनोबल को ऊँचा उठाना । प्रत्येक व्यक्ति को अपने कर्तव्यों का निर्वाह करते हुए अपने को इस भ्रष्टाचार से बाहर निकालना होगा । यही नहीं शिक्षा में कुछ ऐसा अनिवार्य अंश जोड़ा जाए ।
जिससे हमारी नई पीढ़ी प्राचीन संस्कृति तथा नैतिक प्रतिमानों को संस्कार स्वरूप लेकर विकसित हो । न्यायिक व्यवस्था को कठोर करना होगा तथा सामान्य ज्ञान को आवश्यक सुविधाएँ भी सुलभ करनी होगी । इसी आधार पर आगे बढ़ना होगा तभी इस स्थिति में कुछ सुधार की अपेक्षा की जा सकती है ।

The Earth has two types of motions, which lead to seasons and day-night patterns. These motions are – rotation around its own axis and revolution around the Sun. Rotation means the movement of the earth on its axis. It rotates from the west towards the east. Revolution means the movement of the Earth around the Sun in a fixed path or orbit

There is a very narrow zone on Earth where land, water and air come in contact with each other. This is called biosphere. All the living things such as plants, animals, and human being exist only in this zone (the biosphere). So biosphere is of great significance for all of us.

The rajas of mahajanapadas built forts in order to defend their capital city from attacks by other rajas. It is also probable that they wanted to show how rich and powerful they were by building large and powerful walls. The more practical reason could be that it was more easy to govern fortified cities.

Poor rag-pickers like Saheb spend the early years of their lives looking for gold in garbage dumps. The parents of these street children have no fixed income. They wage war against poverty and hunger. They have no dreams except finding the means of survival. Garbage to them is gold. It is the source of their daily bread and provides a roof over their heads. He ends up as a servant at a tea-stall and loses his freedom. Mukesh, the son of a poor bangle-maker of Firozabad, has a dream of becoming a motor mechanic. He wants to learn to drive a car. He thinks of joining a garage to fulfil his dream. He knows that the garage is far away, yet he has decided to walk. He realises the reality and is willing to overcome the obstacles. His daring to rise and decision to get free from the trap laid by vicious moneylenders and middle men arouse a sense of hope.Deprived of education, proper food and upbringing, these children are forced into labour early in life
