the direction depends on the concentration of materials, materials moved by diffusion move from a region of high concentration to a region of low concentration

The passage of water and dissolved materials through a membrabe under pressure?
The movement of water and dissolved materials through a cell membrane is called Osmosis.
What two processes transport materials through the semi permeable membrane?
There's more than two. There's diffusion, facilitated diffusion, and active transport. And water moves by osmosis
What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
Do preying mantis have lungs?
Insects do not have lungs, they breath passively by diffusion through tiny holes in the abdomen.
What allows materials to flow through a cell?
diffusion
What are the process in which materials move through a cell membrane?
diffusion and osmosis
What is the diffusion problem how is it solved in eukaryotic cells?
The diffusion problem is based on relative concentrations in and outside of the cell and a lipid bilayer´s permeability to most of the ions essential to cell processes. It is solved by active transport and facilitated diffusion through protein channels and pumps both passively and through the use of ATP. .... I think ...
Are nutrients absorbed passively or actively in the digestive tract?
Both, depending on the size of the nutrient. Much of absorption works through either endocytosis or transport of small molecules by simple diffusion. Simple diffusion and facilitated diffusion are both types of passive transport and endocytosis requires energy.
Is osmosis a type of passive transport with elements such as calcium?
Osmosis is the passive transport of water, nothing else. Any other substances, such as calcium, are passively transported through the process of diffusion.
