  1. Astrobiology

  2. Astrochemistry

  3. Cosmochemistry

  4. Astrophysics


Correct Option: B
Explanation:

Astrochemistry is the study of the formation, composition, and reactions of molecules in space.

Where have organic molecules been found in space?

  1. Interstellar clouds

  2. Comets

  3. Planets

  4. All of the above


Correct Option: D
Explanation:

Organic molecules have been found in interstellar clouds, comets, planets, and even in the atmospheres of stars.

Which of the following is NOT an example of an organic molecule found in space?

  1. Methane

  2. Water

  3. Ammonia

  4. Formaldehyde


Correct Option: B
Explanation:

Water is not an organic molecule, as it does not contain carbon.

How do organic molecules form in space?

  1. Through chemical reactions between atoms and molecules

  2. Through the action of starlight

  3. Through the action of cosmic rays

  4. All of the above


Correct Option: D
Explanation:

Organic molecules can form in space through chemical reactions between atoms and molecules, through the action of starlight, and through the action of cosmic rays.

Why are organic molecules significant in space?

  1. They may be the building blocks of life

  2. They can provide clues about the formation of the universe

  3. They can help us understand the evolution of stars and planets

  4. All of the above


Correct Option: D
Explanation:

Organic molecules are significant in space because they may be the building blocks of life, they can provide clues about the formation of the universe, and they can help us understand the evolution of stars and planets.
