A Correct answer
Explanation

The Higgs boson is nicknamed the 'God Particle' because its existence was theorized to explain why other particles have mass. The term was popularized by physicist Leon Lederman's book, though physicists generally dislike the nickname. Photons, leptons, and mesons are different types of subatomic particles.

  2. Fat

  3. Protein

  4. Lipids

C Correct answer
Explanation

The Biuret test detects peptide bonds in proteins. When copper(II) sulfate reacts with peptide bonds under alkaline conditions, the solution turns violet/purple. Carbohydrates use tests like Benedict's, fats use ethanol emulsion test, and lipids are tested with Sudan III.

  1. Mercury

  2. Venus

  3. Aeronaut

  4. Moon

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

NASA initially wanted to use "Mercury" to refer to space travelers, but the name was already associated with other projects. They ultimately chose "astronaut" from Greek words meaning "star sailor." The other options (Venus, Moon) are celestial bodies, not proposed terms.

Multiple choice general knowledge science & technology
  1. cosmonauts

  2. taikonauts

  3. aeronauts

  4. none of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Soviet Union used the term "cosmonaut" from the Greek words "kosmos" (universe) and "nautēs" (sailor), while the U.S. used "astronaut." "Taikonaut" is the Chinese term, and "aeronaut" refers to balloon or airship pilots.

Multiple choice general knowledge science & technology
  1. 6 feet, 3 inches tall

  2. 5 feet, 11 inches tall

  3. 5 feet, 7 inches tall

  4. 6 feet, 2 inches tall

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Mercury program had strict height requirements due to the cramped spacecraft cabin. Candidates had to be under 5 feet 11 inches tall. This physical constraint was necessary because the capsule diameter was very limited.

Multiple choice general knowledge science & technology
  1. engineering astronauts and biology astronauts

  2. human astronauts and animal astronauts

  3. pilot astronauts and mission specialist astronauts

  4. navy specialist astronauts and air force specialist astronauts

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

NASA categorizes astronauts into pilot astronauts (who fly the spacecraft) and mission specialist astronauts (who conduct specific experiments or tasks). The other options are incorrect classifications - NASA does not divide astronauts by engineering versus biology, human versus animal, or branch-specific specialties.
