From the following statements,                                                                                         (DEC 2016) a) Hydrogen, Deuterium and Tritium differ in the number of protons. b) Hydrogen, Deuterium and Tritium differ in the number of neutrons. c) Both Deuterium and Tritium are radioactive and decay to hydrogen and deuterium respectively. d) Tritium is radioactive and decays to helium. e) Carbon-14 decays to Nitrogen-14. f) Carbon-14 decays to Carbon-13. Pick the combination with all correct statements. A) a, b and f      B) b, d and e C) a, c and d      D) c, e and f Ans. B - b, d and e Explanation: Hydrogen, deuterium and tritium are isotopes. Isotopes differ in the number of neutrons  and hence statement "b" is correct. Deuterium is non-radioactive but tritium is radioactive. Tritium shows β decay and tritium dec

Visit You tube channel for more MCQ's:  https://www.youtube.com/channel/UCDI5O7VNvIby-Faq_ptLefw Previous Year Questions: 1. Chitin is absent in which group ?                                                                         (Dec 2008) 1) Bacteria          2) Arthropods 3) Fungus            4) Mollusca Ans. 1 - Bacteria Explanation: Chitin is a polysaccharide found in the exoskeleton of arthropods like insects and crustaceans, as well as in the cell wall of fungi, it can also be found in the shells of some molluscs, it is not found in bacteria. Hence option 1 is correct. 2. Which of the following is a most hydrated polymer?                                           (June 2010) 1) Cellulose          2) Pectin 3) Lignin              4) Callose Ans. 2 - Pectin Explanation:  The degree of hydration of a polymer depends on its ability to form hydrogen bonds with water molecules. Among the options provided, pectin is generally considered the most hydrated polymer. Pectin is a polys

1.     Heredity and Evolution Introduction: Basic unit of life is cell. Controlling center of cell is nucleus. Inside nucleus there are chromosomes. Chromosomes are made up of DNA. Segment of DNA is called as gene. ✱ Heredity and Hereditary Changes: Heredity: Transfer of characters from one generation to another via genes. Johann Gregor Mendel - Father of modern genetics. Hugo de Vries - Mutation Theory (1901). Walter and Sutton - Observed paired chromosomes in cells of grasshopper. Ostwald Avery, Maclyn McCarthy and Colin MacLeod - Except viruses, all living organisms have DNA as genetic material (1944). Francois Jacob and Jack Monad - Proposed a model for process of protein synthesis. Science of heredity is useful for: Diagnosis, treatment and prevention of hereditary disorders. Production of hybrid varieties of animals and plants. In industrial processes in which microbes are used. ✱ Structure of DNA (Deoxyribo Nucleic Acid) Chromosomes are made up of DNA. Chromosomes are always in
