The diagram shows a section of a cell membrane that includes a channel protein. The function
of this protein is to -

Which of these is the best model of a prokaryotic cell? - Answer
Loriciferans are microscopic multicellular animals that live in various marine sediments.
Scientists have discovered general of Loriciferans in a deep-sea habitat that lacks oxygen. Before
this discover, some prokaryotes are some unicellular eukaryotes were known to inhabit
anaerobic environments. Among the newly discovered Loriciferans is Splinoloricus sp. nov.,
which is pictured below. Scientists determined that organisms of the genus Spinoloicus were
eukaryotes are not prokaryotes because Spinoloicus cell have
A. flagella
B. hereditary material
C. cell walls
D. nuclear membranes - Answer D. nuclear membranes
The simplicity of prokaryotic cells prevents them from
A. growing and reproducing.
