well viruses are caused by bacteria and bacteria are cells. so yes
A lack of evidence would weaken any theory. But the well known asteroids have well defined orbits.
The simplest answer is that prokaryotic cells do not have a membrane-bound nucleus, and eukaryotic cells do. The nucleus is a compartment where the cell stores its genetic information (DNA). Prokaryotes' DNA is simply within the cytoplasm. Another simple difference is that eukaryotes have membrane-bound organelles, whereas prokaryotes lack this feature.
Well, a Eukariotic cell is a cell with a nucleus. Humans have Eukariotic cells. You can remember this by thinking about the pronunciation. "Eu," and, "you," are pronounced the same. A Prokariotic cell is a cell without a nucleus. These are mostly in plants. I hope that this has helped you.

prokaryotes
Eukaryotic cells has a definite nucleus. It possesses a true nucleus with a definite nuclear membrane. Prokaryotic cells lack a true nucleus. It is scattered with in the cell.
Both prokaryotic and eukaryotic cells can have a cell wall. Cell walls are found in plant cells, bacteria, fungi, algae, and some archaea. However, animal cells and protozoa do not have cell walls.
well viruses are caused by bacteria and bacteria are cells. so yes

Yes; jellyfishes have no head.
prof lj says bacteria contains a mini virus , nucleaus and blood cells as well as micro organisms
Cells with internal membranes (and therefore a defined nuclear membrane/nucleus) are called eukaryotes.Cells with well defined nuclei are called eukaryotic. Eukaryotes include yeast, plants, and animals. Bacteria on the other hand do not have nuclei and are called prokaryotes. Interestingly, there is one very notable exception. Mammals are of course eukaroyotes, however one very specific type of cell, the red blood cell, does not have a nucleus.

Eukarya is the domain that has a true nucleus. Eukaryotes are characterized by having cells with a well-defined nucleus, which houses the genetic material. This distinguishes them from prokaryotes, which lack a nucleus.
