Why is the B+ blood group so common in India and not at all in other parts of the world? India is a tropical country, hence the person living here is exposed to various types of diseases because in this climate the micro-organisms multiply and spread at a much faster rate. Blood group B is related to providing resistance against the diseases,hence the incidence of diseases would be much less in the people having the blood group B. Considering a hypothetical population that has equal number of people in all the blood groups, if there is an advent of a disease, there would be more casualties of the people of the blood group A,AB and O, whereas the people with the blood group B suffers less casualties as their blood group provides resistance.(Theory of natural selection). The survival for the fittest theory have worked years to select the population of India having more number of people of the blood group B. Source: Human Blood and Anthropology #rainbowz

As one of the original members of the United Nations, India enthusiastically supports the purposes and principles of the UN and has made significant contributions in implementing the goals of the organisation. The UN field networks in India are the largest anywhere in the world through the many offices, programmes and funds currently at work in the country. Today, there are 26 UN agencies in India. Some of the milestones that the UN has made in India through its agencies are elaborated upon below: Food and Agriculture Organization (FAO): When FAO began its India operations in 1948, its priority was to transform India’s food and farm sectors throu...

Divisibility by 2 When the last digit of a number is either 0 or even (2,4,6,8), then the number is divisible by 2. Ex - 86, 150, 2358, etc Divisibility by 3 When the sum of the digits of a number is divisible by 3. Ex - 2352 : 2+3+5+2=12        1935 : 1+9+3+5=18 Divisibility by 4 When the last 2-digits of a number is divisible by 4. Apart from this, the number having two or more zeros at the end.  Ex - 5728, 3500 Divisibility b y 5 Number having 0 or 5 at the end are divisible by 5. Ex - 1265, 890, 3400, etc Divisibility by 6 When the number is divisible by both 3 and 2.  Ex - 258, 1944, etc Divisibility by 7 A number is divisive by 7 when the difference between twice the digit at ones place and the number formed by other digits is either zero or a multiple of 7. Ex - 658 : 65-2×8 = 65-16 = 49 Divisibility by 8 When the last 3-digits of a number is divisible by 8. Apart from this, if the last three or more digits are 0. Ex - 2256, 346000, etc D...
