Kolkata (Bengali: কলকাতা / কোলকাতা) /koʊlˈkɑːtɑː/, formerly Calcutta /kælˈkʌtə/, is the capital of the Indian state of West Bengal. Located on the east bank of the Hooghly river, it is the principal commercial, cultural, and educational centre of East India, while the Port of Kolkata is India's oldest operating port and its sole major riverine port. As of 2011, the city had 4.5 million residents; the urban agglomeration, which comprises the city and its suburbs, was home to approximately 14.1 million, making it the third-most populous metropolitan area in India. As of 2008, its gross domestic product (adjusted for purchasing power parity) was estimated to be US$104 billion, which would be third highest among Indian cities, behind Mumbai and Delhi. As a growing metropolitan city in a developing country, Kolkata confronts substantial urban pollution, traffic congestion, poverty, overpopulation, and other logistic and socioeconomic problems.
Life is a characteristic distinguishing physical entities having biological processes (such as signaling and self-sustaining processes) from those that do not, either because such functions have ceased (death), or because they lack such functions and are classified as inanimate. Various forms of life exist such as plants, animals, fungi, protists, archaea, and bacteria. The criteria can at times be ambiguous and may or may not define viruses, viroids or potential artificial life as living. Biology is the primary science concerned with the study of life, although many other sciences are involved.
Throughout history there have been many theories about life including materialism, hylomorphism and vitalism. Even today it is a challenge for scientists and philosophers to define life. The smallest contiguous unit of life is called an organism. Organisms are composed of one or more cells, undergo metabolism, maintain homeostasis, can grow, respond to stimuli, reproduce (either sexually or asexually) and, through evolution, adapt to their environment in successive generations. A diverse array of living organisms can be found in the biosphere of Earth, and the properties common to these organisms are a carbon- and water-based cellular form with complex organization and heritable genetic information.
Mother Teresa (26 August 1910 – 5 September 1997) also known as Blessed Teresa of Calcutta, MC, was an Albanian Roman Catholic religious sister and missionary. She was born in Skopje (modern Macedonia), then part of the Kosovo Vilayet in the Ottoman Empire. After having lived in Macedonia for some eighteen years, she moved to Ireland and then to India, where she lived for most of her life.
Mother Teresa founded the Missionaries of Charity, a Roman Catholic religious congregation, which in 2012 consisted of over 4,500 sisters and was active in 133 countries. They run hospices and homes for people with HIV/AIDS, leprosy and tuberculosis; soup kitchens; dispensaries and mobile clinics; children's and family counselling programmes; orphanages; and schools. Members must adhere to the vows of chastity, poverty, and obedience, as well as a fourth vow, to give "wholehearted free service to the poorest of the poor".
Mother Teresa was the recipient of numerous honours, including the 1979 Nobel Peace Prize. In 2003, she was beatified as "Blessed Teresa of Calcutta". A second miracle was credited to her intercession by Pope Francis, in December 2015, paving the way for her to be recognised as a saint by the Roman Catholic Church.
