In my opinion it is tears.
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
Spectral analysis proposes that there is no hydrogen fusion roughly
speaking. They are hot since they are very thick. So if you are a convinced
high density and temperature and still not doing synthesis, you must be small.
Also, stellar evolution models are founded on the observation of planetary
nebulae, where stars have shed most of their mass after being red giants. The
physics designates a small, hot, central remainder.
One thing I looked up and saw was urine and carbon dioxide.
