Answer:

The correct answer would be "They showed how organic molecules could be made from Earth's early atmosphere."  

Miller-Urey experiment showed the chemical origin of life.

They reproduce the conditions similar to early earth and used chemicals like water, methane, hydrogen, and ammonia.

They induce conditions like water vapors, gaseous mixture, lighting through them, and cycling of the hot and cold atmosphere.

After some time, the presence of organic compounds such as amino acids.

Thus, it showed how organic molecules were formed from early earth's atmosphere.

Smaller muscle groups with a similar functional ability might include the ____________ major which acts as synergist in producin
Oksanka [162]

Answer:

Smaller muscle groups with a similar functional ability might include the antagonist major which acts as synergist in producing the same action as the agonist.

example : the biceps and triceps muscles of arm, work together as agonist and antagonist respectively.

The biceps helps to lift up or flexes the forearm and the triceps helps to extend it.

Explanation:

many muscles work together to make an action happen.

the muscle who is involved in an action principally, is known as prime mover or Agonist muscle.

Antagonist muscle does the opposite action  of the agonist muscle.

antagonist also helps in-

  1. maintaining the body posture or position.
  2. controls the rapid movements.

like, to move a bone , the muscles attached to it work together to make a movement happen. like- to lift up a arm, agonist or prime mover muscles helps to lift up or flex the arm and the antagonist or synergist muscle helps to extend it.

Which one of the following is a combustion reaction?
rosijanka [135]
<span>Combustion reaction is a chemical reaction where compounds and oxidants produce heat and new product during their reaction. The reaction between a HC (hydrocarbon) and O (oxygen) to produce CO2 (carbon dioxide) and H2O (water) is a standard form of a combustion reaction. Therefore,the correct answer would be A. It is the combustion of gas (Methane, CH4) when it encounters oxygen (2O2). Methane will burn forming C02 gas and H20 gas.</span>
