Which is true about diffusion?

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. … One of the main characteristics of diffusion is the movement of molecules along the concentration gradient.

Which of the following statement is correct about simple diffusion?

Diffusion takes place only in gases. Movement of substances takes place from low concentration to high concentration. Movement of substances takes place from high concentration to low concentration.

Which of the following describes diffusion?

Diffusion is the passive movement of molecules or particles from an area of higher concentration to an area of lower concentration.

Which of the following statement is correct about passive diffusion?

Which of the following statements is correct about passive diffusion? It involves movement of molecules down a concentration gradient and may require a transport protein. Which one of the following organisms has a cell wall? pili are used for transfer of DNA and motility.

Which statement is wrong about diffusion?

Larger the difference in concentration, slower is the flow of molecules.

Which statements are correct for both diffusion and osmosis?

Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.

Which of the following statements about diffusion and active transport are correct?

Which of the following statements concerning diffusion and active transport is correct? both diffusion and active transport require cell energy. neither diffusion nor active transport requires cell energy. diffusion requires cell energy while active transport does not.

Is diffusion active or passive?

There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Which of the following is true of osmosis?

Which of the following is true of osmosis? … In osmosis, water moves across a membrane from areas of lower solute concentration to areas of higher solute concentration. In osmosis, water moves across a membrane from areas of lower solute concentration to areas of higher solute concentration.

Which of the following statements is true regarding the movement of substances across cell membranes?

Which of the following statements is true regarding the movement of substances across cell membranes? Ions are unable to move through the phospholipid bilayer because the nonpolar tail regions of the phospholipids are hydrophobic.

Which of the following is a true statement about passive transport?

Which of the following is a true statement about passive transport? Substances naturally move from areas of high concentration to areas of low concentration.

Which of the following statements is correct about passive transport?

which of the following statements about passive transport is correct? passive transport permits the solute to move in either direction, but the net movement of the population of solute occurs down the concentration gradient of the molecule. a selectively permeable membrane separates two solutions.
