. Groups of specialized cells cooperate to form a tissue, such as a muscle.
.This requires that they take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs. Specialized cells perform specialized functions in multicellular organisms.
Hope you have a great day :)

The question is incomplete. The correct question is as following:
__________ studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.
Answer:
Marshall Nirenberg and Heinrich Matthaei
Explanation:
Marshall Nirenberg and Heinrich Matthaei are two biochemist and geneticist who studied the functional importance of RNA in the process of translation (protein synthesis) experimentally in E.Coli.
Nirenberg and Matthaei discovered the first codon out of 64 codons present in RNA and they successfully performed translation (protein synthesis) in E.coli in a test tube. They decoded the first codon UUU (phenylalanine) by using synthetic RNA having only uracil nucleotides in a E.Coli and later they decoded further codons.
So, the correct answer is Marshall Nirenberg and Heinrich Matthaei.
A chemical substance that an organism requires to live. a nutrient that is scarce or cycles slowly through an ecosystem. ensures that nutrients will be circulated throughout the biosphere.
