When the atomic number of one nucleus is the same with the mass number of another nucleus and the mass number the same with the atomic number of the second nucleus, then these two nuclei are called mirror.
Nuclear fusion
bacterial cells do not contain nuclei and are known as prokaryotes. However a special case is red blood cells which do not contain nuclei either and are known as denucleated
chromosome
It means having cells that lack membrane-bound nuclei.
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
There is no specific scientific term known as "mirror nuclie." It is possible you may be referring to "mirror nuclei," which are pairs of atomic nuclei that have the same number of protons and neutrons, but in opposite configurations. These mirror nuclei display symmetry in certain nuclear properties.
Quarks- subatomic particles that make up nucleons
It is known as hail.
When the atomic number of one nucleus is the same with the mass number of another nucleus and the mass number the same with the atomic number of the second nucleus, then these two nuclei are called mirror.
Three helium nuclei, also known as alpha particles, fuse together to form a carbon atom in the process of stellar nucleosynthesis.
The fusion of hydrogen nuclei in the sun produces helium, along with energy in the form of light and heat. This process is known as nuclear fusion and is the source of the sun's energy.
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
