Answer:
An aminoacyl-tRNA synthetase (aaRS or ARS), also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA. It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA.

There are two types of blood that flows through our bodies: oxygenated and deoxygenated. Oxygenated blood is the one that is pumped in the left side of the atrium in the heart. As its name tells us, is the one that is highly with oxygen and low in carbon dioxide. Normally a sample of an oxygenated blood will be very bright in red due to the amount of blood cells in it. Deoxygenated blood is the one that is pumped in the right side of the atrium in the heart. This blood is the one that is low in oxygen and high in carbon dioxide. It is also known as the venous blood. Normally a sample of a deoxygenated blood will be darker almost going on blue.
If an animal cell is surrounded by fresh water, the water will move within the cell causing the cell to become turgid and eventually will burst.
Therefore the most suitable answer is option D.
Answer:
Eubacteria are prokaryotic organisms, as characterized by the lack of a membrane-enclosed nucleus, predominantly unicellular, with DNA in a single circular chromosome, and have peptidoglycan on cell wall when present. They include most of the familiar bacteria of medical and economic importance such as E.
