BR Ambedkar tried to improve the conditions of the Depressed Classes in the following ways: 

In 1930, Dr. BR Ambedkar organised the Dalits (the untouchables) into an organisation called the Depressed Classes Association, now known as scheduled caste. 

• His ideas regarding depressed class deferred from that of Mahatma Gandhi. He wanted separate electorates for Dalits.
• Whilst at Round Table Conference in London he demanded separate electorates for Dalits and the British coloniser conceded his demand. This caused Mahatma Gandhi to fast unto the death because he believed that separate electorate for the Dalits would slow down the process of their integration into the main society. 
• He signed the Poona Pact with Gandhi ji and the Congress giving the opportunities to depress to secure reserved seat for Dalits in the provincial and Central Legislative Council to be voted in general election. 

In chemistry, the most commonly used unit for molarity is the number of moles per litre, having the unit symbol mol/L or mol⋅dm−3 in SI unit. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M.

Calculating Molarity Given Moles and Volume:

We do this by dividing by the molecular weight of NaCl (58.4 g/mole). Then, we divide the number of moles by the total solution volume to get concentration.

Given, 

We know,

Hence, the probability of 'not E' is 0.95

The "Treaty of Constantinople of 1832" recognised Greece as an independent nation.

Apartheid- It was the policy of social discrimination followed in South Africa. This policy divided the people and labelled them on the basis of their skin colour. Under this system, blacks were forbidden from living in white areas. Trains, buses, hotels, hospitals, schools and colleges, libraries, cinema halls, public toilets, etc. were all separate for white and blacks. In South Africa, white did not give equal rights to the native Africans.

India had raised this issue first time in United Nations General Assembly in 1946.

It was due to the constant moral support of India and the continuous struggle of Dr. Nelson Mandela, the policy of apartheid has been abolished in South Africa in 1990.

लोकतंत्र में विपक्षी दल बहुत महत्वपूर्ण भूमिका निभाता है
(i) यह दबाव समूह के रूप में कार्य करता है।
(ii) यह सरकार को जुटाता है।
(iii) यह सत्तारूढ़ दल के कामकाज पर नज़र रखता है।
(iv) यह संसद में अलग-अलग विचार रखता है और अपनी विफलताओं या गलत नीतियों के लिए सरकार की आलोचना करता है।

संसदीय लोकतंत्र की सफलता की एक आवश्यक शर्त यह है की एक संगठित विपक्षों दल अवश्य रहे | भारत का यह दुर्भाग्य रहा है की ब्रिटेन और अमेरिका की तरह यहाँ ऐसा कोई विरोधी दल नहीं हैं जो अकेले अपनी सरकार बनाने में समर्थ हो सके | भारत में राजनीतिक दलों के ध्रुवीकरण की दिशा में कभी ठोस कदम नहीं उठाया जा सका | जयप्रकाश नारायण के प्रयास के फलस्वरूप 1977 के चुनाव के अवसर पर पहली बार विपक्ष ने जनता पार्टी के रूप में उभरकर सत्ता प्राप्त की | परंतु, कालांतर में इस दल ने भी अपने को एक गठबंधन सिद्ध कर दिया और बिखरकर पुनः कई दलों में विभक्त हो गया | प्रतिपक्षी एकता के प्रयास के फलस्वरूप 1983 में भारतीय जनता पार्टी और लोकदल द्वारा राष्ट्रीय लोकतान्त्रिक मोर्चा तथा जनता पार्टी का कांग्रेस (स), लोकतान्त्रिक सामाजिक दल और राष्ट्रवादी कांग्रेस द्वारा गठित संयुक्त मोर्चा बना, परंतु यह कांग्रेस (इ) का विकल्प नहीं बन सका | कुछ हद तक चुनावी तालमेल में भले ही इन्हे सफलता मिली, परंतु, भारतीय राजनीति में इनकी कोई स्पष्ट भूमिका देखने को नहीं मिल सकी | 

1966 तक कांग्रेस (इ) पार्टी शसक्त बनी रही, परंतु 1966 के बाद लोकसभा चुनावों में भारतीय जनता पार्टी एक सशक्त दल के रूप में उभरकर आई और कांग्रेस (इ) को विपक्ष की ही भूमिका निभाने के लिए बाध्य होना पड़ा | 2004 में परिस्थिति में हल्का परिवर्तन हुआ और 2004 के लोकसभा चुनाव में सदन में सर्वाधिक स्थान पानेवाली पार्टी भारतीय राष्ट्रीय कांग्रेस ही रही | कई दलों को मिलाकर एक संयुक्त 
प्रगतिशील गठबंधन बना और केंद्र में इसी गठबंधन की सरकार बनी | इस प्रकार आठ वर्षों के अंतराल के बाद कांग्रेस पुनः सत्तारूढ़ दल की श्रेणी में आ गई | भारतीय जनता पार्टी को लोकसभा में विपक्ष की भूमिका निभाने के लिए बाध्य होना पड़ा | 2014 के लोकसभा चुनाव के बाद भारतीय जनता पार्टी के नेतृत्त्ववाले गठबंधन (राजग) के सत्ता में आने के बाद कोई भी दल विरोधी दल का दर्जा पाने में असमर्थ रहा |

There are three different stages in the formation of urine by the filtration of blood through the nephrons. The process of urine formation in kidneys include the following steps:
(i) Glomerular filtration - Urine formation begins when the blood is filtered by the glomerulus then enters the Bowman's capsule and the glomerular filtrate is formed. The afferent arteriole entering the glomerulus is wider than the efferent arteriole in diameter. This increases the blood pressure within the glomerulus helps in the filtration. Glomerular filtrate is formed of all blood constituents except corpuscles and plasma proteins.
(ii) Tubular reabsorption - When the glomerular filtrate comes to the proximal tubule then the essential nutrients are reabsorbed. Glucose, amino acids, water, ions like sodium, potassium, chloride, bicarbonate, magnesium, calcium are reabsorbed from the glomerular filtrate. When the filtrate finally comes to the collecting duct ADH (anti-diuretic hormone) acts and reabsorbs the excess water and decreases the urine volume.
(iii) Tubular secretion - When the glomerular filtrate is in the proximal tubule creatinine, uric acid are secreted in it. When the filtrate goes to the distal part urea, potasium ion and some hydrogen ions are secreted in the form of urine.

1. Form the pair of linear equations in the following problems, and find their solutions graphically.

(i) 10 students of Class X took part in a Mathematics quiz. If the number of girls is 4 more than the number of boys, find the number of boys and girls who took part in the quiz.

(ii) 5 pencils and 7 pens together cost 50, whereas 7 pencils and 5 pens together cost 46. Find the cost of one pencil and that of one pen.

Solution:

(i)Let there are x number of girls and y number of boys. As per the given question, the algebraic expression can be represented as follows.

x +y = 10

x– y = 4

Now, for x+y = 10 or x = 10−y, the solutions are;

For x – y = 4 or x = 4 + y, the solutions are;

The graphical representation is as follows;

As hibiscus flower contains the colour pigment anthocynanin, not only can it be used as a natural indicator, it can also be used to produce natural dye that is eco-friendly and safe on human skin. Acid-base indicators are chemicals used to determine whether an aqueous solution is acidic, neutral, or alkaline. Because acidity and alkalinity relate to pH, they may also be known as pH indicators. Examples of acid-base indicators include litmus paper, phenolphthalein, and red cabbage juice.
