Number of bones in the human body of an adult is

A. 202
B. 204
C. 206
D. 208

Answer & Solution
Option: C
Explanation :The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21. The human skeleton can be divided into the axial skeleton and the appendicular skeleton. The axial skeleton is formed by the vertebral column, the rib cage, the skull and other associated bones. The appendicular skeleton, which is attached to the axial skeleton, is formed by the shoulder girdle, the pelvic girdle and the bones of the upper and lower limbs.
The human skeleton performs six major functions; support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation.

    Which country Researches Successfully Test Artificial Blood On Living Beings?

    A. China
    B. Japan
    C. Canada
    D. South Africa

    Answer & Solution
    Option: B
    Explanation :Researchers in Japan claim that they have developed artificial blood that can be transfused into people irrespective of their blood type and can substantially boost the chances of recovery in critically injured people. The artificial blood has proved highly effective on rabbits and was developed by a team of experts based primarily at the National Defense Medical College.
    The artificial blood, when used in humans, works around the issue of identifying blood types in critical situations and helps deal with limits on real blood storage from donors as the artificial blood can be stored at normal temperatures for more than a year. Manabu Kinoshita, an associate professor of immunology at the National Defense Medical College and a member of the team said:
    It is difficult to stock a sufficient amount of blood for transfusions in such regions as remote islands. The artificial blood will be able to save the lives of people who otherwise could not be saved.

      Which new mineral is discovered inside in diamond in South Africa?

      A. Goldschmidtite
      B. Nixonite
      C. Tinnunculite
      D. Bazinga

      Answer & Solution
      Option: A
      Explanation :A Ph.D. student at the University of Alberta has discovered a new and curious mineral inside a diamond unearthed from a mine in South Africa. The mineral—named “goldschmidtite” in honor of Victor Moritz Goldschmidt, the founder of modern geochemistry—has an unusual chemical signature for a mineral from Earth’s mantle, explained Nicole Meyer, a graduate student in the Diamond Exploration Research and Training School.
      “Goldschmidtite has high concentrations of niobium, potassium and the rare earth elements lanthanum and cerium, whereas the rest of the mantle is dominated by other elements, such as magnesium and iron,” said Meyer. “For potassium and niobium to constitute a major proportion of this mineral, it must have formed under exceptional processes that concentrated these unusual elements.”
      The study, “Goldschmidtite, (K,REE,Sr)(Nb,Cr)O3: a New Perovskite Supergroup Mineral Found in Diamond from Koffiefontein, South Africa,” was published in American Mineralogist.

        Which is the longest day of the year?

          Which is the shortest day of the year?

          A. 28th December
          B. 25th December
          C. 22nd December
          D. 15th December

          Answer & Solution
          Option: C
          Explanation :The winter solstice December 22 marks the shortest day of the year. A solstice occurs twice a year, when the sun’s position in the sky, as viewed from Earth, reaches its farthest points north and south from the celestial equator. According to the Meteorology Department on December 22, with sunrise at 7:06am and sunset at 5:07pm, the day would be 10.1 hours long. Henceforth, the days would start lengthening and nights shortening form December 23.

            Which one is called Wonder Drug?

            A. Birth control pill
            B. Viagra
            C. Aspirin

            Answer & Solution
            Option: D
            Explanation :Discovered in 1928 and put to use to cure infections in 1942 this is arguably the most important drug discovery in the history of medicine. It began the era of antibiotics and ushered in advances in therapeutic medicine. In fact, there’s a good chance you wouldn’t be reading this if not for the drug, as it likely prevented an infection in yourself or one of your ancestors.
            The U.S. Centers for Disease Control and Prevention estimates that antibiotic resistance is responsible for more than 2 million infections and 23,000 deaths each year.
            Some other Wonder Drugs are Aspirin, Viagra, Birth control pill, Lipitor, Insulin, Thorazine, HN-2/Mechlorethamine, AZT, Ritalin
