Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some scientists believe that the first monomers on early Earth came from meteorites that fell to Earth. What evidence do scientists use to support this theory?
A
An experiment conducted by Stanley-Miller simulated meteorite conditions and were able to produce important monomers.
B
Pieces of meteorites that have been found to contain a variety of organic chemicals.
C
The astronomer Edward Hubble observed this happening on other planets.
D
Meteorites are amphiphilic and therefore are capable of carrying foreign molecules through Earth’s atmosphere.
Explanation: 

Detailed explanation-1: -Some scientists believe that the first monomers on early Earth came from meteorites that fell to Earth. What evidence do scientists use to support this theory? An experiment conducted by Stanley-Miller simulated meteorite conditions and were able to produce important monomers.

Detailed explanation-2: -The study of meteorites has helped us understand the beginnings of our solar system, how planets and asteroids formed and how impacts of large meteorites have altered Earth’s history and life on our planet.

Detailed explanation-3: -70% of various nitrogen sources were converted to ammonia within 15 minutes. Thus, the early formation of organic monomers could have been supported by the production of ammonia from these vents.
