Which of the following evidence supports that the "rna world" hypothesis is valid? a. creation of suitable environments for long-term study of single-celled organisms b. simulation of early earth conditions and long-term study of the resulting molecules c. development of a system for studying the microsphere's ability to absorb additional molecules d. categorization of the different conditions that result in the development of microspheres

The correct answer is option B, that is, simulation of early Earth conditions and long-term study of the resulting molecules

Explanation:

It is considered that the initial molecules on the planet Earth were made spontaneously via the reactions taking place from the energy arising from Earth's heat and lightning. It is considered that these molecules with time produced polymers via catalysis with the assistance of metals present in the oceans.  

These polymers exhibited the tendencies to self-replicate and also function as enzymes as they also possess the tendency to fold up. In order to prove the hypothesis, the conditions of that time of the Earth needed to be replicated, the collection of data had to be done, and evaluation has to be made.  

the correct answer is sex-linked recessive.
