What is the channel in the nuclear membrane through which the RNA passes?
The nuclear PORE membrane
What controls what passes in and out of cells?
Through something called "Selective permeability"
What is a osmosis?
osmosis is a movement of a fluid that passes through a semipermable membrane
What is the nuclear membrane and what does it do?
The nuclear membrane is a double membrane surrounding the chromosomes of a eukaryotic cell.Together with associated structures, it is called the nuclear envelope. Perforations in the double membrane are termed pores; each is surrounded by a group of proteins collectively called the nuclear pore complex.The nuclear membrane defines the limit of the organelle called the nucleus. The membrane is broken into fragments during the first phase (prophase) of nuclear division. The fragments travel through the endoplasmic reticulum to the poles of the dividing cell, and are used to form the nuclear membranes of the daughter-cells.The pores permit large molecules to enter and leave the nucleus. For example, after transcription messenger RNA passes through a pore on its way to the cytoplasm for translation. And proteins synthesized in the cytoplasm enter the nucleus via pores before being incorporated in ribosome subunits being assembled in the nucleolus. These subunits subsequently leave the nucleus through the pores.
Water passes through a cell membrane by?
What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
What is the channel in the nuclear membrane through which the RNA passes?
The nuclear PORE membrane
Water passes quickly through cell membranes because?
The cell membrane has two phospholipids, with hydrophilic (water-loving) heads facing the outside while the hydrophobic tails point in. Water cannot pass through because of this characteristic. The hydrophilic "heads" attract water since they are polar, but the hydrophobic "tails" are non polar and reject water. H20 passes by means of a channel protein.
What is the substances that passes through a cell?
cell membrane
Can Hydrogen peroxide pass through a cell membrane?
yes, H2O2 passes through cell membrane through passive transport.
Where does oxygen go after it passes through the the cell membrane?
The Mitochondria
What controls what passes in and out of cells?
Through something called "Selective permeability"
The process by which simple sugar passes through a membrane is called?
diffusion
What is a osmosis?
osmosis is a movement of a fluid that passes through a semipermable membrane
What is a type of diffusion in which water passes through a cell membrane?
Osmosis

What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
Is a membrane made of proteins?
Cell membranes consist of a bilayer phospholipid (hydrophobic tails and hydrophyllic heads), cholesterol, glycolipids (grow off phospholipids) and glycoproteins (grow off proteins), intrinsic Proteins (passes through both layers), extrinsic proteins (passes through only one layer). Finally, a channel protein/ transport protein/carrier protein, allow big molecules (glucose) to pass through the cell membrane.
