What molecules diffuses through the lipid portion of the plasma membrane?
Any hydrophobic ones. eg. steroids
The RNA type that diffuses through the nuclear pores to direct the assembly or synthesis of new protein molecules at the ribosomes in the cytoplasm is what?
tRNA, or transfer RNA
Where does CO2 enter the chloroplast?
It diffuses through the membrane.
How does oxygen get in and out of plasma membrane?
Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
What is the route that oxygen takes to get to the red blood cells?
If by that you mean where they get their own oxygen, then from nowhere because red blood cells do not need oxygen, they perform all reactions anaerobically.If you mean where they get it to give off for the rest of your body, then its from the lungs.

Why does glucose diffuse through dialysis tubing into distilled water?
Glucose diffuses through dialysis tubing into the distilled water as, glucose molecules are small, it could fit through the pores of the dialysis tube. It is also because glucose is hydrophillic, (polar compound), which will dissolve in water as it is a polar compound as well.
Oxygen diffuses into the blood from the?
o2 diffuses into blood from alveoli of lungs through the respiratory membran.
How is facilitated diffusion differing from diffusion?
Simple diffusion allows non-polar molecules to pass through and a little amount of H20. On the other hand, Facilitated diffusion allows ions and polar molecules across the membrane because it contains carrier proteins. It is highly specific to substances it diffuses across the membrane.
Where does CO2 enter the chloroplast?
It diffuses through the membrane.
Inhaled oxygen diffuses through the walls of the?
cells
Oxygen diffuses through what structure?
A semipermeable membrane.
What are methanogenic bacteria and how do they produce methane?
NO bacteria are methanogenic, archaea are methanogenic. And they produce it through a process called chemolithoautotrophy, where they break down the inorganic molecules into energy.

Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
In haled oxygen diffuses through the walls of the?
Alveoli in the lungs.
Water molecules diffuse through a selectively permeable membrane?
Water diffuses by facilitated diffusion, passing through water permeable protein channels embedded in the cell membrane. Water molecules can not pass through the lipid bilayer because water is polar. However, polar molecules pass though the cell membrane through the protein channels. The proteins that aid water in passing through the cell membrane are called aquaporins. "Aqua" for water, and "porin" for pore. A "water pore" in essence.
