Diffusion

Diffusion takes place within

• liquids and solids

• gases and liquids

• solids and gases

• solids, liquids and gases

This image displays:

• Higher concentration of red molecules in A compared to B

• Diffusion of red molecules will take place from B to A

• Higher concentration of red molecules in B compared to A

• Diffusion of yellow molecules will take place from A to B

What process has occurred between the broken down food (amino acids, monosaccharides) with the bloodstream of the villi:

• osmosis

• transfer of matter

• concentration

• diffusion

Proteins are broken down into:

• lipids

• amino acids

• monosaccrides

• fatty acids

Diffusion is the movement of particles in a substance from an area of:

• high to low concentration

• hot to cold temperature

• low to high concentration

• between concentrations equally

What is that arrow displaying that is occurring?

• movement of particles from low concertation to no concentration

• fusion of particles so equilibrium is reached

• movement of particles from low concentration to high concentration

• movement of particles from high concentration to low concentration

Fats are broken down into:

• fatty acid and lipase

• lipase and polypeptides

• fatty acid and glycerol

• fatty acids and polypeptides

How does the diffusion gradient constantly fluctuate between the bloodstream and alveoli within the lungs?

• The flow of the bloodstream carries away the platelets

• The flow of the bloodstream carries away the oxygen

• The concentration is stable within the bloodstream and alveoli

• The gradient is automatically kept constant via the brain
