- Question 1 of 5
1. Question
1 pointsCategory: Science and TechnologyThe term ‘StrandHogg’ is related which of the following?
Correct
Explanation: The Union Ministry of Home Affairs (MHA) has sent an alert to all States warning them about the vulnerability of Android operating system to a bug called ‘StrandHogg’, which allows real-time malware applications to pose as genuine applications and are able to access user data of all kind. The information was shared by Threat Analytical Unit, Indian Cyber Crime Coordination Centre (ICCCC) so as to take steps to create awareness among public on vulnerability of Android to ‘StrandHogg’.

2. Question
1 pointsCategory: Science and TechnologyConsider the following statements about Vitamin C:
1. Only Vitamin C is to be taken externally, all others are produced in the human body.
2. Vitamin C is the only vitamin which is also a hormone.
3. Scurvy is caused by the deficiency of Vitamin C
4. Vitamin C is a water-soluble vitamin.
Which of the above given statement is/are correct?Correct
Explanation: Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesize vitamin C endogenously, so it is an essential dietary component. Vitamin C is required for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters; vitamin C is also involved in protein metabolism. Insufficient vitamin C intake causes scurvy, which is characterized by fatigue or lassitude, widespread connective tissue weakness, and capillary fragility.

3. Question
1 pointsCategory: Science and TechnologyThe location approved for setting up the India based Neutrino Observatory is in the district of:
Correct
Explanation: The India-based Neutrino Observatory (INO) Project is a multi-institutional effort aimed at building a world-class underground laboratory with a rock cover of approx.1200 m for non-accelerator based high energy and nuclear physics research in India. The initial goal of INO is to study neutrinos. It is a mega-science project jointly funded by the Department of Atomic Energy (DAE) and the Department of Science and Technology (DST).
The Neutrino project includes:
•Construction of an underground laboratory and associated surface facilities at Pottipuram in Bodi West hills of Theni District of Tamil Nadu.
•Construction of an Iron Calorimeter (ICAL) detector for studying neutrinos.
•Setting up of National Centre for High Energy Physics at Madurai, for the operation and maintenance of the underground laboratory, human resource development and detector R&D along with its applications.Incorrect

4. Question
1 pointsCategory: Science and Technology: Consider the following statements about YUVIKA Scheme:
1. The Scheme is launched by Ministry of Human resource and development.
2. It is aimed at imparting basic knowledge on Space Technology, Space Science and Space Applications to the younger ones with the intent of arousing their interest in the emerging areas of Space activities.
Which of the above given statement is/are correct?Correct
Explanation: Indian Space Research Organisation has launched a special programme for School Children called “Young Scientist Programme” “YUva VIgyani KAryakram” from this year, in tune with the Government’s vision “Jai Vigyan, Jai Anusandhan”.
The Program is primarily aimed at imparting basic knowledge on Space Technology, Space Science and Space Applications to the younger ones with the intent of arousing their interest in the emerging areas of Space activities. The program is thus aimed at creating awareness amongst the youngsters who are the future building blocks of our Nation. ISRO has chalked out this programme to “Catch them young”.Incorrect

5. Question
1 pointsCategory: Science and TechnologyConsider the following statements:
1. Satellite whose orbital period is equal to the period of rotation of the earth (24 hrs) are placed in geostationary orbit.
2. The satellite which stays right over the same spot all the time is placed in Geosynchronous Orbits
Which of the above given statement is/are correct?Correct
Explanation: Geosynchronous Orbits (GSO)
•Another solution to the dwell time problem is to have a satellite whose orbital period is equal to the period of rotation of the earth (24 hrs) (satellite’s revolution is in sync with the earth’s rotation).
•In this case, the satellite cannot be too close to the Earth because it would not be going fast enough to counteract the pull of gravity.
•By positioning a satellite so that it has infinite dwell time over one spot on the Earth, we can constantly monitor the weather in one location, provide reliable telecommunications service, etc.
•The downside of a GSO is that it is more expensive to put and maintain something that high up.
Geostationary Orbit or Geosynchronous Equatorial Orbit (GEO)
•A geostationary orbit or geosynchronous equatorial orbit is a circular geosynchronous orbit above Earth’s equator and following the direction of Earth’s rotation.
•Because the satellite stays right over the same spot all the time, this kind of orbit is called “geostationary.”Incorrect
