The CNS are lined by ependymal cells. Ependymal cells are epithelial cells that monitor the composition of cerebrospinal fluid (CSF)
The answer would be meteorites containing amino acids. Most of the amino the amino acids revealed in the new investigation were not guaranteed up in proteins or polymers. Furthermore, the most plentiful amino acids originate in biology are those that are set up in proteins, but such "proteinogenic" amino acids signify only a small fraction of the amino acids originate in the meteorites.
Prokaryotes are usually smaller than eukaryotes. They also don’t have a nucleus so DNA is in the cytoplasm. They also have no organelle membranes where as eukaryotes do. Domains of prokaryotes include Bacteria and Archaea, and all eukaryotes are in the domain Eukarya. Both can be free living, but only eukaryotes can be multicellular. Prokaryotes first appeared on earth about 3.5 billions then eukaryotes appeared about a billion years later. Etc....
Vitamin B6 is essential for the synthesis of T cells. These cells form part of the immune system.
<h3>What is Vitamin B6?</h3>
Vitamin B6, also called pyridoxine, is a water-soluble micronutrient found in different types of foods.
Vitamin B6 is required to generate T cells and white blood cells (lymphocytes), which are cells of the immune system.
Vitamin B6 is also fundamental for the generation of interleukin-2, which is a molecule involved in immune responses.
