Ice & dust.
the thalamic nuclei is made of unmyelinated axons which are gray matter
Atomic nuclei (and alpha particales, but these are exactly the same as Helium nuclei)
No. An artery is a closed "pipeline" for the blood; the cells it is made of have nuclei, the cells it transports have nuclei, but the artery itself does not.
- hydrogen nuclei waiting to be fused into helium and - helium which has been fused from hydrogen nuclei

both archaea and bacteria are domains that are made up of prokaryots. prokaryots do not have a nucleus. the only domain that is known to have nuclei is eukarya.
the answer is cytosine
no, the sun is plasma. a mixture of fully ionized hydrogen and helium nuclei (with traces of other nuclei) and free electrons.
Yes, nuclei are typically visible in tissue samples when viewed under a microscope. Nuclei contain DNA and are stained with dyes to make them more visible for analysis. They appear as dark, round structures within the cell.
The nucleus is primarily composed of nucleic acids (DNA and RNA) and proteins. It also contains nucleoli, which are responsible for producing ribosomal RNA, as well as other structural components like nuclear pores and the nuclear envelope.
curium
No, they are also made up of neutral partials called neutrons.
