By definition, baryonic matter should only include matter composed of baryons. In other words, it should include protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude things such as electrons and neutrinos which are actually leptons. since on astronomical scales, protons and neutrons are always accompanied by electrons (in appropriate numbers for astronomical objects to possess all but zero net charge). Astronomers therefore use the term ‘baryonic’ to refer to all objects made of normal atomic matter, essentially ignoring the presence of electrons which, after all, represent only ~0.0005 of the mass. Neutrinos, on the other hand, are (correctly) considered non-baryonic by astronomers.

<h3>What are the various parts of the brain?</h3>

The brain is the most important organ found in the body. The brain controls all the other processes occurring in the body.

The brain consists of cells called neurons which are interconnected to each other and which receive information from other parts of the body, processes it and sends out response signals.

The various parts of the brain are as follows:

subdural space
third ventricle
fourth ventricle
lateral ventricle
foramen of magendie
pia matter
corpus callosum
straight sinus
arachnoid villa
foramen of monroe
dura matter
skull - the protective covering of the brain
subarachnoid space
cerebral aqueduct
choroid plexus
arachnoid
cerebellum
cerebrum

In conclusion, the various parts of the brain function to make the brain work efficiently.

During protein synthesis, what does mRNA do?

zubka84 [21]

Answer:

No direct answer but this might help out a little bit: <3

Explanation:

The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its base sequence, and uses the genetic code to translate each three-base triplet, or codon, into its corresponding amino acid.
