Consider the following statements:
1 Mustard seeds have high levels of glucosinolates, a group of sulphur and nitrogen-containing compounds contributing to the characteristic pungency of their oil and meal.
2. High glucosinolates in rapeseed meal are known to cause goiter and internal organ abnormalities in livestock.
Which of the following statements is/ are correct?
  • (A) 1 only
  • (B) 2 only
  • (C) Both 1 and 2

ANSWER: C

 

Consider the following statements:
1. Obligately hydrocarbonoclastic bacteria consume hydrocarbons as a sole carbon and energy source.
2. Alcanivorax borkumensis bacteria form “dendritic” biofilms that reshape oil droplets but decrease the rate of bioremediation.
Which of the following statements is/ are incorrect?
  • (A) 1 only
  • (B) 2 only
  • (C) Both 1 and 2
  • (D) Neither 1 nor 2
Show Answer

ANSWER: B

  • Obligately hydrocarbonoclastic bacteria (OHCB) survive by consuming hydrocarbons as a sole carbon and energy source.
  • These marine bacteria play an integral role in the bioremediation of spilled petroleum worldwide.
  • Alcanivorax borkumensis (or Alca), an aerobic and rod-shaped OHBC that feasts on organic acids and alkanes, bloom during oil spills to exploit the hydrocarbons contained within crude oil.
  • “Oil-eating” Alcanivorax borkumensis bacteria form “dendritic” biofilms that reshape oil droplets, and increase the surface area to speed up the rate of consumption.
Consider the following statements:
1 Side Channel Attacks hack systems based on the analysis of auxiliary systems used in the encryption method.
2. Acoustic Side Channel Attacks use sound of keyboard clicks to hack.
3. Which of the following statements is/ are correct?
  • (A) 1 only
  • (B) 2 only
  • (C) Both 1 and 2
  • (D) Neither 1 nor 2
Show Answer

ANSWER: C

SIDE CHANNEL ATTACKS (SCAS)

  • SCAs are a method of hacking a cryptographic algorithm based on the analysis of auxiliary systems used in the encryption method.
  • These can be performed using a collection of signals emitted by devices, including electromagnetic waves, power consumption, mobile sensors, sound from keyboards and printers to target devices.
  • Once collected, these signals are used to interpret signals that can be then used to compromise the security of a device.

ABOUT ACOUSTIC SIDE CHANNEL ATTACKS

  • In an ASCA, the sound of clicks generated by a keyboard is used to analyse keystrokes and interpret what is being typed to leak sensitive information.
  • These attacks are particularly dangerous as the acoustic sounds from a keyboard are readily available and because their misuse is underestimated by users.
  • While most users hide their screens when typing sensitive information, no precautionary steps are taken to hide the sound of the keystrokes.
  • Additionally, the use of laptops has increased the scope of ASCAs as laptop models have the same keyboard making it easier for AI-enabled deep learning models to pick up and interpret the acoustics.
  • They have an accuracy beyond 90%.
Consider the following statements:
1 A large number of megalithic hat stones have been excavated in Tirunavaya, Tamil Nadu.
2. Tirunavaya is located on the banks of river Bharathapuzha.
Which of the following statements is/ are incorrect?
  • (A) 1 only
  • (B) 2 only
  • (C) Both 1 and 2
  • (D) Neither 1 nor 2
Show Answer

ANSWER: A

  • A large number of megalithic hat stones were found from a single site during a recent archaeological salvage excavation conducted by the Kerala State Archaeology Department at Nagaparamba in Kuttippuram village, near Tirunavaya.
    • Tirunavaya is located on the banks of river Bharathapuzha.
  • Hat stones, popularly called Thoppikkallu in Malayalam, are hemispherical laterite stones used as lid on burial urns during the megalithic period.
  • Archaeologists say it could arguably be the largest number of hat stones in an unprotected site in the State.
  • A large number of earthen urns and iron implements with unique features were discovered during the excavation, which could ostensibly throw light on the life and culture of people who lived in those parts more than 2,000 years ago.
The first airport in north east to introduce the innovative ‘Digi Yatra‘ facility is at-
  • (A) Dispur
  • (B) Agartala
  • (C) Shillong
  • (D) Guwahati
Show Answer

ANSWER: D

  • Guwahati’s Lokpriya Gopinath Bordoloi International Airport (LBBI) has become the first airport in the north east to introduce the innovative ‘Digi Yatra‘ facility.
  • The Digi Yatra initiative has been introduced in collaboration with the Ministry of Civil Aviation, with the goal of modernizing air travel and streamlining airport processes.

ABOUT DIGIYATRA

  • It is a paperless entry at airports using facial recognition software.
  • It envisages that travellers pass through various checkpoints at the airport through paperless and contactless processing, using facial features to establish their identity, which would be linked to the boarding pass.
  • It is being implemented by the DigiYatra Foundation
    • Digi Yatra Foundation (DYF), is a not- for- profit company under section 8 of Companies Act 2013 incorporated on 20 February 2019.
    • Digi Yatra Foundation was set up with initial shareholding of Airport Authority of India (AAI), Cochin International Airport (CIAL), Bangalore International Airport (BIAL), Delhi International Airport Ltd. (DIAL), Hyderabad International Airport Ltd (HIAL) & Mumbai International Airport Ltd (MIAL).
