Answer:
The answer is b. Both of them are characterized by selective permeability.
Explanation:
- Option a. states that both, the nuclear and the cell membrane have two layers. This is only true for the nuclear membrane that consists of two lipid bilayers whereas the plasma membrane only contains one layer.
- c. Only the nuclear membrane has nuclear pores that connect the two bilayers. The pores act as protein channels or passages that allow transport of materials. The cell membrane does contain channel proteins or transmembrane proteins but not protein channels.
- d. The nuclear membrane separates nuclear contents from the cytoplasm whereas the cell membrane separates cellular contents from the extracellular environment.
Protozoa are Eukaryotic organisms, they show animal/plant like behaviors. Bacteria are prokaryotic, very tiny simple single celled organisms with no nucleus or mitochondria.
Ferns don’t have to be in a tropical setting, but they can.
It’s a bad question.
