When a snake flicks its tongue, it is gathering odor particles for transfer to two fluid-filled sacs at the roof of the mouth -- Jacobson's organs -- that lead to a second, smaller olfactory chamber. The tongue is used only to assist in this process; snakes do not have a sense of taste.
A eukaryote is a type of cell (or unicellular organism) that possesses a nucleus and membrane-bound organelles, in contrast to prokaryotes (bacteria and archaea) which don't. Eukaryote means good/true nut/kernel in Greek, referring to the nucleus, while prokaryote means before nut/kernel.
Eukaryotic cells are living things that contain a nucleus that make up of three domains or basic division of life. Most eukaryotic cells are larger than the cell of archaea and bacteria.Eukaryotic cells appear most recently like some things that are alive such as plant,animals,humans,and water.Of the three domains of life probably between 1-5 billion or 2 billion years ago.ost eukaryotic cells are larger than the cell of archaea and bacteria.
