Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Hot dilute soup is also called primitive broth.
Reason (R): It contains complex micromolecules like enzymes and DNA.
In light of the above statements, choose the correct answer from the options given below.
Assertion (A): Hot dilute soup is also called primitive broth.
Reason (R): It contains complex micromolecules like enzymes and DNA.
In light of the above statements, choose the correct answer from the options given below.
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true but (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
C. (A) is true but (R) is false.
Step-by-step solution
Assertion (A) is true because J.B.S. Haldane described the primitive ocean as a "hot dilute soup" or "primitive broth" where organic compounds accumulated and chemical evolution took place.
Reason (R) is false because the primitive broth contained simple organic molecules and early polymers, but not highly complex macromolecules like enzymes and DNA, which evolved much later. Furthermore, enzymes and DNA are macromolecules, not micromolecules.
Answer: (A) is true but (R) is false.
Reason (R) is false because the primitive broth contained simple organic molecules and early polymers, but not highly complex macromolecules like enzymes and DNA, which evolved much later. Furthermore, enzymes and DNA are macromolecules, not micromolecules.
Answer: (A) is true but (R) is false.
