Eukaryotes most likely evolved from prokaryotes.

they are eukaryotes.
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
No.
Evolution of Eukaryotes took approximately 1.5 billion years .

Yes, they all are!

Eukaryotes evolved from a process call endosymbiosis. Endosymbiosis states that eukaryotes started as two separate bacterium. The bigger bacteria engulfed the smaller. This is how the mitochondria is enclosed in the cell. There is evidence of this because the mitochondria has its on cell membrane and contains its own DNA.
For the most part, eukaryotes are multicellular, but there are exceptions.
Other eukaryotes may eat eukaryotes and some prokaryotes may eat eukaryotes.
Prokaryotes do not have a nucleus included in their cells. Eukaryotes do have a nucleus included in their cells. And prokaryotes are more simple, it is the simplest, but eukaryotes are very complicated. And prokaryotes are single cells, but most of the eukaryotes make a big organism like plants and animals.Eukaryotes have membranes around their organalles
They are prokaryotes so did not evolve in the same way as eukaryotes. Bacteria are "simpler" organisms but have a highly complicated structure of their own
