    Explanation:


    India has successfully launched the communication satellite GSAT-18. The satellite was launched by a heavy duty rocket of Arianespace from the spaceport of Kourou in French Guiana.

    The European launcher Ariane-5 VA-231 injected GSAT-18 into a Geosynchronous Transfer Orbit (GTO) shortly after orbiting co-passenger Sky Muster II satellite for Australian operator, National Broadband Network.

    After its injection into GTO, ISRO's Master Control Facility (MCF) at Hassan took control of GSAT-18 and performed the initial orbit raising manoeuvres using the Liquid Apogee Motor (LAM) of the satellite, placing it in circular Geostationary Orbit.

    2. A new A new frog species, which closely resembles the Graceful tree frog (Litoria Gracilenta), was discovered recently in which of the following country?
    a. India
    b. Australia
    c. Oman
    d. Japan

    A new frog species, which closely look likes the Graceful tree frog (Litoria Gracilenta), was recently discovered in Australia’s largest virgin forest in Queensland. The frog discovered in Queensland’s Cape York was only determined to be a new species after undergoing rigorous tests for a year, scientist Jodi Rowley told Xinhua news agency.

    Rowley, one of the scientists said her colleague Keith McDonald from the Queensland museum had first laid eyes on the Cape York tree frog, scientifically known as Litoria Bella, in 2000 during one of his field-work outings.

    4. Which of the following scientists has been awarded with 2016 Nobel Prize in Medicine for his discoveries of mechanisms for autophagy?
    a. Yoshinori Ohsumi
    b. David J. Thouless
    c. Richard Feynman
    d. Jean-Pierre Sauvage

    Answer: c

    Explanation:


    Yoshinori Ohsumi, a Japanese cell biologist, has been awarded with the 2016 Nobel Prize in Physiology or Medicine for his discoveries of mechanisms for autophagy. Macro autophagy (“self-eating”, hereafter referred to as autophagy) is an evolutionarily conserved process whereby the eukaryotic cell can recycle part of its own content by sequestering a portion of the cytoplasm in a double-membrane vesicle that is delivered to the lysosome for digestion. Unlike other cellular degradation machineries, autophagy removes long-lived proteins, large macro-molecular complexes and organelles that have become obsolete or damaged.

    Autophagy mediates the digestion and recycling of non-essential parts of the cell during starvation and participates in a variety of physiological processes where cellular components must be removed to leave space for new ones. In addition, autophagy is a key cellular process capable of clearing invading microorganisms and toxic protein aggregates, and therefore plays an important role during infection, in ageing and in the pathogenesis of many human diseases.
