1.What is the primary benefit of using GM crops?
  • AIncreased crop yield
  • BImproved crop quality
  • CEnhanced resistance to pests and diseases
  • DAll of the above

Explanation

GM crops can provide several benefits, including increased crop yield, improved crop quality, and enhanced resistance to pests and diseases.
2.What is the purpose of the Cas9 enzyme in the CRISPR-Cas9 system?
  • ATo bind to the target DNA sequence
  • BTo cut the target DNA sequence
  • CTo repair the cut DNA sequence
  • DTo transcribe the target DNA sequence

Explanation

The Cas9 enzyme is a key component of the CRISPR-Cas9 system, and its primary function is to cut the target DNA sequence. This cut creates a double-stranded break in the DNA, which can then be repaired by the cell using one of two main mechanisms: non-homologous end joining (NHEJ) or homology-directed repair (HDR).
3.Which of the following is a potential application of biotechnology?
  • ADevelopment of new materials
  • BProduction of biofuels
  • CCreation of artificial intelligence
  • DExploration of space

Explanation

Biotechnology has the potential to produce biofuels, such as ethanol and biodiesel, from renewable biomass sources.
4.What is the primary objective of the Aditya-L1 mission?
  • ATo study the Sun's corona
  • BTo study the Earth's natural resources
  • CTo study the space debris
  • DTo study the Jupiter's atmosphere

Explanation

The Aditya-L1 mission is a solar coronagraph mission that aims to study the Sun's corona.
5.

What is MedSigLIP?


  • A

    A diagnostic tool for skin cancer detection.

  • B

    A lightweight medical image and text encoder recommended for structured tasks like classification or retrieval.

  • C

    A specialized model for interpreting veterinary health data.

  • D

    The regulatory arm of Google DeepMind for health AI.

Explanation

  • Option (b) is correct: MedSigLIP is part of the HAI-DEF collection, optimized for structured medical image tasks and efficient enough to run on mobile hardware.

6.

In the context of sports science research, consider the following statements regarding the evolution of "talent":

  1. Modern perspectives increasingly view athletic talent as a dynamic, multidimensional system rather than an innate, static trait.

  2. Talent identification is now conceptualized as a one-off selection event focused on isolated physical indicators.

  3. Environmental, cultural, and social factors are considered critical influences in the modern identification and development process.

  • A

    1 and 2 only

  • B

    2 and 3 only

  • C

    1 and 3 only

  • D

    1, 2, and 3

Explanation

Statement 1 and 3 are correct. The source context notes that the view of "innate talent" is being replaced by a dynamic, multidimensional view (Statement 1) that values environmental and social factors (Statement 3). Statement 2 is incorrect because the research emphasizes that talent identification should be a "long-term, dynamic evaluation process" across diverse environments, not a one-off event.

7.Which of the following is a potential application of synthetic biology?
  • AProduction of biofuels
  • BDevelopment of new medical treatments
  • CCreation of artificial intelligence
  • DExploration of space

Explanation

Synthetic biology has the potential to produce biofuels, such as ethanol and biodiesel, from renewable biomass sources, providing a sustainable alternative to fossil fuels.
8.Which of the following space agencies is responsible for the development of the International Space Station?
  • ANASA
  • BESA
  • CISRO
  • DRoscosmos

Explanation

The International Space Station is a joint project between NASA, ESA, Roscosmos, and other space agencies.
9.

With reference to the interstellar comet 3I/ATLAS, consider the following statements:

  1. It is estimated to have formed 12 billion years ago, when the cosmos was roughly 13% of its current age.

  2. It was born in a significantly colder environment (-243°C) compared to our solar system's formation conditions.

  3. Its chemical and isotopic makeup was measured using the Hubble Telescope’s recent deep-space probe.

Which of the statements given above is/are correct?

  • A

    1 and 2 only

  • B

    2 and 3 only

  • C

    1 and 3 only

  • D

    1, 2, and 3

Explanation

  • Statement 1 is correct: Researchers believe 3I/ATLAS formed 12 billion years ago, dating to when the cosmos was 13% of its current age.

  • Statement 2 is correct: The comet was born in an environment at -243°C, much colder than the earth or our solar system.

  • Statement 3 is incorrect: While the source includes a Hubble image, it explicitly states that researchers measured the ratio of isotopes using the James Webb Space Telescope.

10.What is the primary objective of the NASA's SpaceX Crew-1 mission?
  • ATo send humans to the Moon
  • BTo send humans to Mars
  • CTo send humans to the International Space Station
  • DTo develop a reusable launch vehicle

Explanation

The SpaceX Crew-1 mission is a NASA mission that aims to send humans to the International Space Station.
