Answer:
A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length,that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA does this by carrying an amino acid to the protein synthetic machinery of a cell (ribosome) as directed by the complementary recognition of a 3-nucleotide sequence (codon) in a messenger RNA (mRNA) by a 3-nucleotide sequence (anticodon) of the tRNA. As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins in accordance with the genetic code.
Each mRNA molecule is simultaneously translated by many ribosomes, all reading the mRNA from 5′ to 3′ and synthesizing the polypeptide from the N terminus to the C terminus. The complete mRNA/poly-ribosome structure is called a polysome.
tRNAs in eukaryotes
The tRNA molecules are transcribed by RNA polymerase III. Depending on the species, 40 to 60 types of tRNAs exist in the cytoplasm. Specific tRNAs bind to codons on the mRNA template and add the corresponding amino acid to the polypeptide chain. (More accurately, the growing polypeptide chain is added to each new amino acid bound in by a tRNA.)

Therefore, tRNAs are the molecules that actually “translate” the language of RNA into the language of proteins.
A decrease in the autonomic tone of the smooth muscle in a blood vessel would result in an increase in blood flow through the vessel.
<h3>Meaning of smooth muscle</h3>
smooth muscle can be defined as a muscle in the body that is non striated and involuntary in nature.
Smooth muscles are mostly found in hollow organs, passageways and tracts of some systems.
In conclusion, A decrease in the autonomic tone of the smooth muscle in a blood vessel would result in an increase in blood flow through the vessel.

I think it’s all of the above because they can all be found in the air and in water sources
Answer:
A. A light burned out and "opened" the circuit
Explanation:
In a parallel circuit if a light bulb goes out the rest are fine because they each have independent routes to the battery. But in a series circuit when a light bulb goes out the rest goes out because the current is going in one pathway. To tell the difference of if it closed or opened the circuit, you have to know what they mean. Closing a circuit means a complete electrical connection, the light bulbs will light and electricity will flow. Opening a circuit means the opposite. If the all the light bulbs have stopped working then the circuit is not complete, therefore it's open.
